WHEN SERVICE ELEC SYSTEM IS FLASHING. PLEASE CHECK FOLLOWING:-

1. Check for a voltage drop to the Power Train Control Module (PCM) and Electronic Brake Control Module (EBCM) when the problem is happening.

2. If the voltage is less than Battery Voltage (B+) when the problem happens check for a voltage drop through the ignition switch. Tech Tips: SERVICE ELECTRICAL SYS - 106
The IPC illuminates the SERVICE ELECTRICAL SYS -- 106 message in the DIC when one of the following conditions exist:

• The Dash Integration Module (DIM) detects a malfunction that is related to the ignition switch.

The IPC receives a class 2 message requesting illumination from the DIM.

• There is a Powertrain related code present.

The IPC receives a class 2 message requesting illumination from the PCM.

Conditions for Setting the DTC P1574
A 2.5 mph or greater decrease in non-drive wheel speed in 0.4 second and extended travel brake switch or TCC brake switch indicating brakes applied and no transition noticed in the stop lamp contacts of the stop lamp switch.
ALSO CHECK FOR FAULT CODES IN THE OBD.

The service engine soon light indicates you have a problem with the engine management system.The only way to get it to stay off is to lacate and repair whatever is not working correctly. Requires very specialized equipment. Take it to your mechanic.

First thing you have to do is list all the codes, because some some might be stored for a long time. Pushing the OFF and WARM buttons together and holding will ghive you all the stored codes. Then press OFF and HI together to clear all codes. Hold and wait for bars or 0's. Now start your car and let it get up to proper operating temps. Take car for aride that aincludes all phases of driving including highway speeds. Observe SERVICE ENGINE LIGHT for coming on . Assuming it does , repeat steps previously provided, read codes stored and repair accordingly. If need be contact me with new codes and I will try to assist you.

SOURCE: have 96 seville service emission system is displaying,

Turn your key to the On position ( don't start it ) now, on your heat/air panel, press and hold the OFF and the WARMER (red) buttons at the same time for about 8sec. You will see your dash light up with every segment lit, you can let go when it starts. Then you computer will run its diagnostic check for error codes. Have a pen and paper ready to copy them down. As a guess, I bet it's going to throw a O2 sensor code. Let me know the codes. After that just turn your key off and your done with that portion.

SOURCE: cadillac seville won't start

I've got an even cheaper and easier solution, instead of buying a new cylinder, find that plug and snip the orange wires going to the old cylinder.Then remove the resistor chip from the key and solder each of the the wires to each side. this will fool the car into thinking the correct resistor chip is in place, allowing you to use the original key or any copies with or without resistor chips. i just did this to my caddy and it roared to life! :)

Can a pcm kill all power to the car

No, the Powertrain Control Module only does powertrain, but can prevent starting.

Lights and locks are the domain of the Body Control Module. Having said that, your Cadillac has dozens of large and small modules.

Check the fuses,

WHY DOESNT MY 2003 CADILLAC SEVILLE HAVE ANY POWER AND DOESNT WANT TO SHIFT EASILY

1. Verify the exhaust system is not plugged. Check for less than 1.5 PSI backpressure at 2,000 RPM in park, or open the exhaust before the converter.

2. Check the Manifold Absolute Pressure Sensor (MAP) for 4.8-5.0 volts Key On Engine Off (KOEO) and about 1 volts at idle.

3. Check actual engine vacuum at idle at 2000 RPM.

4. Unplug the Mass Air Flow (MAF) sensor, reset fuel trim to 0%, and road test. ALSO CHECK FOR FAULT CODES IN THE OBD SYSTEM.

My car wont stay on. the starter works and it makes a noise like its turning on but doesnt stay. could it be an electric problem? the car is a cadillac seville 1990. i had a mechanic take a look and try to...

Does it have a security system? If it does see if the security light is flashing. If it is you can reset most cars by turning the ignition to on and waiting for the security light to go off. Then it will start. This will happen again.

Just a wild guess.
