Diagnostic Aids
• The RPA system is equipped with an on-board diagnostic display feature capable of displaying diagnostic trouble codes from the RPA display. Before using this diagnostics, it is necessary to get familiar and understand how the on-board diagnostic feature operates. Refer to Diagnostic Trouble Code (DTC) Displaying and to Diagnostic Trouble Code (DTC) Clearing on how the diagnostic trouble codes are displayed and cleared from the RPA display system.
• Make sure the rear park assist (RPA) object sensors located on the vehicle rear bumper are clean and clear. Remove any objects that is blocking the sensors.
• Inspect for after market devices which could affect the operation of the RPA system.

Diagnostic Trouble Code (DTC) Displaying

This vehicle is equipped with an on-board diagnostic display feature capable of displaying diagnostic trouble codes using the 3 indicators on the rear parking assist display. After the bulb check has been completed, the red outside indicator flashes to indicate a malfunction with the system. The module disables operation of the URPA system under this condition.
In order to enter the diagnostic mode, complete the following actions:
With the ignition turned OFF, short the rear parking assist diagnostic connector to ground while the vehicle is in PARK. For the location of the rear parking assist (RPA) diagnostic connector, refer to Object Detection Component Views .
Turn ON the ignition.
Place foot on the brake.
Shift the vehicle into REVERSE within 5 seconds.
If the vehicle is not shifted into reverse within 5 seconds after turning the ignition ON, the diagnostic mode will still be initiated. However, a reverse input wiring fault will be registered as sequence #7 as shown in the Diagnostic Indicator table below. Refer to Diagnostic Trouble Code (DTC) Clearing for the specific steps on how to clear diagnostic trouble codes. After the reverse input wiring code is cleared, repeat the diagnostic trouble code displaying steps in order to enter the diagnostic mode.
When the diagnostic mode is first entered, the rear parking assist display displays the amber outside indicator and the red outside indicator. Then, the indicators on the rear parking assist display will display one or more of the sequences in the table below to indicate where the fault exists within the rear parking assist system. Refer to Diagnostic Trouble Code (DTC) Clearing for the specific steps on how to clear diagnostic trouble codes.

The Rear Parking Assist (RPA) Diagnostic Connector (UD7) is under the front of the center console behind the BCM - body control module.

1987-97 VEHICLES EXCEPT 1997 MODELS WITH 16-PIN DLC

See Figures 1 and 2
Listings of the trouble for the various engine control system covered in this manual are located in this section. Remember that a code only points to the faulty circuit, NOT necessarily to a faulty component. Loose, damaged or corroded connections may contribute to a fault code on a circuit when the sensor or component is operating properly. Be sure that the components are faulty before replacing them, especially the expensive ones.

Fig. Fig. 1: ALDL/DLC terminal identification for 1987-97 vehicles, except 1997 models with a 16-pin DLC
The Assembly Line Diagnostic Link (ALDL) or Data Link Connector (DLC) may be located under the dashboard, and is sometimes covered with a plastic cover labeled DIAGNOSTIC CONNECTOR.

1. The diagnostic trouble codes can be read by grounding test terminal B . The terminal is most easily grounded by connecting it to terminal A (internal ECM ground). This is the terminal to the right of terminal B on the top row of the ALDL connector.
2. Once the terminals have been connected, the ignition switch must be moved to the ON position with the engine not running.
3. The Service Engine Soon or Check Engine light should be flashing. If it isn't, turn the ignition switch OFF and remove the jumper wire. Turn the ignition ON and confirm that the light is now on. If it is not, replace the bulb and try again. If the bulb still will not light, or if it does not flash with the test terminal grounded, the system should be diagnosed by an experienced driveability technician. If the light is OK, proceed as follows.
4. The code(s) stored in memory may be read through counting the flashes of the dashboard warning lamp. The dash warning lamp should begin to flash Code 12. The code will display as one flash, a pause and two flashes. Code 12 is not a fault code. It is used as a system acknowledgment or handshake code; its presence indicates that the ECM can communicate as requested. Code 12 is used to begin every diagnostic sequence. Some vehicles also use Code 12 after all diagnostic codes have been sent.
5. After Code 12 has been transmitted 3 times, the fault codes, if any, will each be transmitted 3 times. The codes are stored and transmitted in numeric order from lowest to highest.

The order of codes in the memory does not indicate the order of occurrence.

1. If there are no codes stored, but a driveability or emissions problem is evident, the system should be diagnosed by an experienced driveability technician.
2. If one or more codes are stored, record them. Refer to the applicable Diagnostic Code chart in this section.
3. Switch the ignition OFF when finished with code retrieval or scan tool readings.

After making repairs, clear the trouble codes and operate the vehicle to see if it will reset, indicating further problems.

your 98 buick is equipped with an obd2 diagnostic system, a faulty cam sensor will throw a trouble code causing a check engine or service engine soon light. however cylinder misfire or poor signal to coil pack/packs would be a symptom if for some reason the obd2 or ecm was faulty and not throwing a code

There is a Service Bulletin #01205 for the 2004 Lincoln Navigator- ENGINE AND ENGINE COOLING:ENGINE:GASOLINE
Some vehicles may exhibit vacuum or air leaks in the intake manifold and / or engine system causing diagnostic trouble codes P0171 and or P0174

If the only code 52 is flashing then system is ok and just needs to be cleared.Look behind the glove box and find the gray 2 wire connector.It will be on the left side behind the glove box and follow the proceedure below. Once a fault has been serviced, the associated diagnostic trouble code may be cleared from NVM. Only diagnostic trouble codes that the air bag diagnostic monitor sees as repaired or intermittent may be cleared (diagnostic trouble codes 52 and above). In no circumstances can hard fault conditions (diagnostic trouble codes 45 and below) be cleared.

1. Follow the diagnostic procedures as outlined to service the fault condition flashing on the air bag indicator.

1. Cycle the ignition switch to OFF and then to RUN.

1. Observe air bag indicator prove-out (six ±two seconds) followed by diagnostic trouble code (52-85) flashing completely one time.

1. Locate the Diagnostic Service Connector located underneath the glove compartment containing Circuits 631 (T/R) and 57 (BK).

1. Use a jumper wire to short Circuit 631 (T/R) to Circuit 57 (BK) or to another good ground.

1. Hold short until air bag diagnostic monitor tone sounds (approximately five seconds).

1. Release short on Circuit 631 (T/R) to Circuit 57 (BK). Diagnostic trouble code is now cleared from NVM. Next highest priority diagnostic trouble code stored in NVM (if one exists) will begin flashing
   

Try clearing the codes & see if it returns. I do not see a code fault 10. Starts at 12.

Section 01-20B: Restraints, Passive — Supplemental Air Bag System 1995 Town Car, Crown Victoria, Grand Marquis Workshop Manual DIAGNOSIS AND TESTING Diagnostic Trouble Code Clearing Procedure to Clear Diagnostic Trouble Codes from Diagnostic Monitor Non-Volatile Random Access Memory.
Normal Operation
The air bag diagnostic monitor (14B056) continually checks the air bag system for readiness. When a fault condition is detected, the DTC associated with that fault is stored in the air bag diagnostic monitor's Non-Volatile Random Access Memory (NVRAM). After writing the DTC to NVRAM, the air bag diagnostic monitor signals the fault by flashing the appropriate diagnostic trouble code on the air bag indicator. The diagnostic trouble code written to NVRAM is permanently stored in the air bag diagnostic monitor until cleared by the diagnostic trouble code clearing procedure.

• Upon each cycle of the ignition switch (11572) , the air bag diagnostic monitor checks for diagnostic trouble codes written in NVRAM. If any diagnostic trouble codes exist in NVRAM, the air bag diagnostic monitor will then check to see if these fault conditions are still present.
• If the conditions of the diagnostic trouble code in NVRAM are still present, then the air bag diagnostic monitor will use the air bag indicator to flash out the diagnostic trouble code number that was written in memory.
• If the conditions of the diagnostic trouble code are not still present (indicating an intermittent or serviced fault), the air bag diagnostic monitor will use the air bag indicator to flash out a DTC which is the sum of the diagnostic trouble code in NVRAM plus 40.

Example: Due to corrosion, high resistance develops on the driver side air bag circuit. The air bag diagnostic monitor stores a diagnostic trouble code 32 in NVRAM. Upon each cycle of the ignition switch , the air bag diagnostic monitor checks the resistance of the driver air bag circuit.

• If the resistance is still high, the air bag diagnostic monitor causes the air bag indicator to flash out a DTC 32.
• If the resistance falls within the normal range due to service or an intermittent condition, the air bag diagnostic monitor causes DTC 72 to be flashed on the air bag indicator.

Once a fault has been serviced, the associated diagnostic trouble code may be cleared from NVRAM. Only diagnostic trouble codes that the air bag diagnostic monitor sees as repaired or intermittent may be cleared (diagnostic trouble codes 52 and above). In no circumstances can hard fault conditions (diagnostic trouble codes 45 and below) be cleared.

1. Follow the diagnostic procedures as outlined to service the fault condition flashing on the air bag indicator.

1. Cycle the ignition switch to OFF and then to RUN.

1. Observe air bag indicator prove-out (six ± two seconds) followed by diagnostic trouble code (52-85) flashing completely one time.

1. Locate the Diagnostic "Trouble Code Clear" Connector located underneath the glove compartment (06010) containing Circuits 631 (T/R) and 57 (BK).

1. Use a jumper wire to short Circuit 631 (T/R) to Circuit 57 (BK) or to another good ground. This short must be made after the diagnostic trouble code flashes completely one time, but before the warning light stays on continuously.

1. Hold short until air bag diagnostic monitor tone sounds (approximately five seconds).

1. Release short on Circuit 631 (TAN/RED STRIPE) to Circuit 57 (BLACK). This short must be released within 25 seconds after the diagnostic monitor tone sounds. Diagnostic trouble code is now cleared from NVRAM. Next highest priority diagnostic trouble code stored in NVRAM (if one exists) will begin flashing.
