INTERMITTENT AIR BAG LIGHT - 2006 Chrysler PT Cruiser

Check with dealer might be a recall for defective srs.

it has an intermittent connection.
finding them , will be hard.
there reason they cant find it, is it s good when you take it in.
so avoid dealers. they are too busy making cash (stacks)
find and independent ASE shop, that will drive the car until it fails.

as they say, you can't fix it, if it is not broke. rules. earth.
also inspect all connnectors, (using the fSM rules for air bag defeat first)

TROUBLE CODE CLEARING

1. Follow the diagnostic procedures to service the fault condition flashing on the air bag indicator prior to code clearing.

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

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

4. Locate the Diagnostic "Trouble Code Clear" Connector (grey connector). located underneath the glove compartment, left side (06010) containing Circuits 631 (T/R) and 57 (BK).

5. 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.

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

7. Release short on Circuit 631 (T/R) to Circuit 57 (BK). This short must be released within 25 seconds after the diagnostic monitor tone sounds.

Diagnostic trouble code is now cleared from memory. Next highest priority diagnostic trouble code stored (if one exists) will begin flashing.

The codes and clearing proceedure above are to be used as a guide, NO claims are implied as to the correctness or accuracy of either.

The airbag light on the dashboard comes for few reasons, either there is a bad connection or connection came loose but than the light would stay on at all times, if it comes periodically than I would look up to the owner's manual and also find the airbag check label inside the car as it might be faulty or in need of replacement. The danger is that if it is faulty it can blow up by itself or in case of accident (hope none happens) it will malfunction.

A flashing airbag light can mean one of two things. The first possibility is that your battery is in death row. Have it tested at your local parts store. The second possibility is that there is an actual problem with the airbag system. Below is a list of airbag codes, which will flash on the warning light. For example, the light will flash once, pause and then flash twice == 12.

12=Low Battery Voltage
13= Air Bag Circuit Shorted to Ground
14=Primary Crash Sensor Circuit Shorted to Ground
21=Safing Sensor Not Mounted to Properly
22=Safing Sensor Output Shorted to Battery Voltage
23=Safing Sensor Circuit Input Feed/Return Circuit Open
24=Safing Sensor Output Feed/Return Circuit Open
32=Driver Side Air Bag Circuit High Resistance or Open
33=Passenger Side Air Bag Circuit High Resistance or Open
34=Driver Side Air Bag Circuit Low Resistance or Shorted
35=Passenger Side Air Bag Circuit Low Resistance or Shorted
41=RH Primary Crash Sensor Feed/Return Circuit Open
42=LH Primary Crash Sensor Feed/Return Circuit Open
44=RH Primary Crash Sensor Not Mounted to Vehicle Properly
45=LH Primary Crash Sensor Not Mounted to Vehicle Properly
51=Air Bag Diagnostic Monitor Internal Thermal FuseFuse Blown Due to Intermittent Short to Ground
52=Backup SupplyVoltage Boost Fault
53=Primary Crash Sensor Circuits Resistance to Ground or Air Bag Diagnostic Fault

Hope this helps...

Something shaking is almost always a cylinder misfiring.
Which is usually a bad plug or wire. But it could also be an intake manifold vacuum leak.

could be a steering wheel sir coil,,,behin d the steering wheel there is a sir coil which electrically connects the air bag to the car thru this coil that allows the steering wheel to turn with out getting twisted wires,but sometimes that coil and have intermitent contact and give a air bag light at times,could be other things , but most likely that,no way to check it,,,get the trouble code and that will lead you more in a direction on it,,prob just gotta replace it, i would take to dealer if you misinstall the new one you can wreck it,,

Sounds like an air bag problem. You will not be able to reset the light without fixing the problem. The steering wheel airbag electrical contact is suspect. Airbag will have to be removed and problem repaired. . I do not recommend you repair the problem unless qualified.

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.
   

CLEARING CODES (works for code 52)
1. Only intermittent codes and codes that diagnostic monitor recognizes as being repaired may be cleared from memory. To clear codes, cycle ignition OFF to ON. Observe AIR BAG warning light. AIR BAG warning light will illuminate for 4-8 seconds, and flash fault code.

(Comment) Loosely translated - If you dont have the problem fixed, this wont work. Code 52 should clear with this!

2. Locate air bag diagnostic 2-pin connector.

(Comment) This was a fun one. According to the air bag wiring diagram that I also got from Mitchell, the Airbag Diagnostic Connector is located "Right side of Instrument Panel". The only thing I found immediately to the right of the I/P (between the stereo and Instrument panel) was a black computer with 4 connectors which is NOT what I was looking for. I finally found a blog that mentioned the computer for the air bag computer was behind the right side kick panel. Sure enough....there it was. Attached to the side of the diagnostic computer was a two prong diagnostic connector.

3. Connect a jumper wire between diagnostic connector terminals. Leave jumper wire connected until diagnostic monitor tone sounds (about 5 seconds). Disconnect jumper wire. Fault code is cleared.
