take it back for a warranty check
could be a spun bearing problem or a simple oil pressure sensor/sender unit

ICM - ignition module problem , driver (transistor ) shorted to ground .

1997 Cadillac... | Answered on Mar 04, 2018

what could be the problem ???? The problem is you tried to fix something you have no clue how it works .... Your best bet , take it to a qualified repair shop. You have no idea of the complexity of these cadillac systems . I know you don't have a $ 5000 dollar factory scan tool or equivalent to diagnose . The sending unit in the fuel tank is a input to the BCM . The BCM sends this info to the instrument cluster over the class 2 serial data network - communication network for the control modules on the vehicle. Fuel Level
The body control module (PZM) monitors the fuel level sender input in order to determine the current fuel level. The PZM filters the input and sends a message via the Class 2 serial data line. The IPC receives this message and displays the current fuel level. The fuel level is sent from the PZM to the IPC at changes of 0.5 L (0.02 gal) or on the request of the IPC, with a resolution of 0.04 L (0.01 gal).
• For the digital IPC, when the fuel level is above 18.5 gal, the IPC displays an F. For readings between 18.5-2.5 gal, whole gallon/liter numbers are displayed. When the fuel level reaches 3.0 gal the message FUEL LEVEL LOW is displayed on the driver message center. When the fuel level reaches 2.5 gal, the IPC displays an E. When the fuel level is 1.2 gal or below the IPC displays a flashing E.
• For the analog IPC, when the fuel level is above 18.5 gal, the fuel gauge pointer is on F. When the fuel level is below 2.5 gal the fuel gauge pointer moves to E. When the fuel level is below 3.0 gal the IPC displays a FUEL LEVEL LOW message.
If the updates are not received or a communication error is detected, the IPC performs the following actions:
• For the digital IPC, the fuel gauge is dashed.
• For the analog IPC, the fuel gauge pointer moves to E.

Fuel Gage Inaccurate or Inoperative
Circuit Description
The IPC monitors the fuel level sent by the PZM through the class 2 serial data line. The IPC software controls one of the following two gauge types:
• A digital gauge consisting if a two-digit numeric seven-segment display
• An analog gauge consisting of a needle pointer.
The IPC interpolates and scales the fuel level information that the IPC receives from the PZM.
When you operate the vehicle in diagnostic mode, either in the vehicle diagnostic system or with a scan tool connected, the fuel signal supplied to the IPC is not filtered by the PZM. The unfiltered fuel signal causes the IPC to show real time readings and may be mistaken as an erratic fuel level display.
Diagnostic Aids
Connect a scan tool to the DLC.
Test for any set DTCs if no DTCs are set current. Refer to System Check in Body Control Module (PZM) Diagnosis.

Your best bet , take your vehicle to a qualified repair shop.

the instrument clusters are a known problem in these vehicles. Look for a rebuilder online. A rebuilt one runs little less than $200

it went into a drag. What ????? What Ignition light ??? You mean the starter was dragging from trying to start it to long . Drained the battery ? From the ignition light , i'm think your talking about the anti-theft system . Really can't make heads or tails out of what your trying to say here , Your best bet ,take it to a qualified repair shop . Without test we'd only be guessing .

I, myself own a 1993 Cadillac Sedan Deville. It has over 150K miles on the odometer and has over time had a myriad of parts replaced, mostly by me. One day, for reasons unknown, the window in the driver's side door decided not to work. Like you, all other windows remained fully operable in both directions. While the switches can fail they are, as a rule, quite reliable for long periods of time. When trying, for some time, to get the window to operate, without success, I thought, let me think about this. Upon reflection, I decided that although switch failure is possible the odds of both sets of contacts, raise and lower, failing simultaneously are small.
The next possibility is that the window regulator which is what the manufacturer calls the mechanism, has developed a motor problem. These are DC motors and I don't know whether they have a wound field ar a permanent magnet field. Assuming a wound field it is possible that the last time the window moved under power the motor stopped with a brush either stuck or in contact with a "dead spot" on the commutator. Assuming the latter and with the window fully up I opened the door, pressed the switch to lower the window and while holding the switch in the down position I simultaneously slammed the door. Voila!!! The window went down and became fully operable once more. It has been operating as designed ever since; about 8 months now. Give it a try. Window regulator assemblies are dear and the motor is NOT available as a separate part. Good Luck!!

The check engine light doesn't have to come on with a bad crank sensor ,your vehicle has two , one for lower rpm an one for higher speeds . A&B
The two crankshaft sensors are located on the front bank (BANK 2) of the engine block between cylinders 4 and 6. Crankshaft position A sensor is located in the upper crankcase and crankshaft position B sensor is located in the lower crankcase. Both sensors extend into the crankcase and are sealed to the engine block with O-rings. The crankshaft position sensors are not adjustable.

If the stereo was removed, the speakers may have been removed as well. Did you check if they are there?
Also, you need to make sure the car didn't have a Bose system installed - that system adds an amp between the radio and the speakers, and if the amp is in place, your aftermarket radio can't use it (if it is there or has been removed, you will have to bypass the connectors at the amp location so the wiring at the radio can reach the speakers directly).
In any case, you need to find and look up the entertainment system option installed when the car was built, and the get a wiring diagram for that system (try Alldatadiy.com).

The only one to be concerned about right off isP0603 "Control Module long term reset". Once this is figured out the other codes will probably clear.

Possible causes Loose or poor battery terminal connection Low battery charge Engine Control Module (ECM) / Powertrain Control Module (PCM) power supply circuit is open or shorted ECM/PCM Programing Faulty ECM/PCM

There are a number of think's that could cause this . wont start right away when ? First start of the day ,anytime ? Testing would have to be done to know for sure . IF it seams to run fine after it does start ,it would be a fuel pump or filter problem . More then like a fuel management system sensor problem . mass air flow sensor comes to mind . But having a qualified repair Tech . looking at scan data on a professional type scan tool Should be the thing to do.
048 Engine Hard to Start or No Start Scan Data for Starting Problems
Plus checking fuel system for bleed off .
Car cranks too long Fast fuel pressure bleed off Faulty regulator Part 2
