Using the Cadillac on-board diagnostic display you'll also see "IP" for the IPC instrument panel, "AC" for the air conditioning module, "TC" for traction control, "RS" for the road suspension system, "SD" for the air bags, "PZ" for the body control module, "CC" for the cell phone and "RF" for the integrated radio.

WHAT DOES CODE IP1910 & - b447af8.jpg

B1910 - Generator L-Terminal Open Circuit

B2750 - PASSKey Data Communication Failure

B1312 - High Side Temp Sensor Open Circuit

B0077 - Left Front/Driver Side Impact Sensor (SIS) Malfunction

Its all that I find for the momento; go to the automotive reference section. They should have the factory service manuals. I don't think you can check them out but you can use them to look up the error codes.

If I find other details, send you; hope helps.

    RS0011 = Will Set When
    1. If the RSS control module senses the drive line low and the return line low for three consecutive samples during an "ON" command, a code will set.
    2. Or, if the RSS control module senses the drive line low and the return line low for three consecutive samples during a PWM high state command, a code will set.
    3. Or, if the RSS control module senses the drive line high and the return line low during the 5 to 20 mS portion of the "ON" command and also does not sense the drive line high and the return line high during the "OFF" command, a code will set.

    For a drive line short to ground, the RSS control module will stop driving all four damper solenoids. For a return line short to ground, the RSS control module will stop driving only the affected damper solenoid. The module will then wait 5 seconds, attempt driving the solenoid again, and sense the drive and return lines. If the fault is not present, the RSS control module resumes normal operation. Otherwise, it will repeat the stop-wait-retry-sense sequence. A software counter is incremented for each fault observed or decremented for each fault not observed. If the counter reaches three counts at any time, the solenoid is de-energized for the remainder of the ignition cycle, a code is set, and the "SERVICE RIDE CONTROL" message is displayed.

    1. The RSS control module senses the drive line low and the return line high during the "OFF" and the PWM low state commands.
    2. The RSS control module senses the drive line high and the return line low during PWM high state command.

    Diagnostic Aids.
    History codes are used to help diagnose intermittent fault conditions and do not necessarily indicate a faulty RSS control module. The RSS control module itself is a reliable component and is not likely the cause of the malfunction. Most system complaints are linked to faulty wiring and connectors and, occasionally, components. Performing a thorough inspection of all related wiring and connectors pertaining to the history code stored will reduce diagnostic time and prevent unnecessary part replacement. If the problem is intermittent, try performing the tests shown while "wiggling" wiring and connectors. This can often cause the malfunction to appear. Check for poor connections at both the RSS control module and the related components. These could cause an open, short, or an intermittent malfunction.

    RS0038 = Electronic Level Control Exhaust Valve Short to Ground/Open.
    This is a problem with the solenoid that
    lets air out of the system. Usually it's caused by water that somehow
    got into the system and rusted or otherwise corroded something away. I
    just fixed this same problem on my 96 Seville.

    You can buy the ELC parts separate from a dealership or from There is a pump mechanism
    that includes the ELC exhaust valve and an air dryer. I think I
    remember pricing both parts at about $450-500 online, and the dealership
    wanted over $600. I wound up buying a used one that came from an Olds
    Aurora for $100. The mounting bracket was different, but easy to change
    over, and it saved quite a few bux as you can see.

    On the 96 Seville, the pump and dryer are mounted above the rear axle.
    It's a little tricky to find all the bolts that hold it up there, but
    none of them are hard to remove. You will probably have to remove the
    clip and air dryer cylinder from the pump assembly before you can remove
    the whole thing from above the axle. Just be sure you keep the
    mounting brackets in case you get a used one from a different car. When
    you remove the brackets, be very careful not to get dust or other
    contaminants into the crankcase of the new pump. Also be careful not
    to cut the plastic air lines by pinching them or rubbing them against
    something sharp or abrasive. If there are already cracks or holes in
    the air lines, replace them before replacing the pump.

    Once you've replaced the pump, also check the ELC fuse and replace if
    necessary. Clear out the RS0038 code or disconnect the battery for 30
    seconds and you should be in business. You will probably notice the
    pump kick on when you turn the ignition on, and the exhaust valve
    letting a bit of air out when you turn it off and get out of the car.

Does the purge valve keep the engine from starting?

You got the code

You can google the code to learn about it

Type: OBD PO443

The internet will explain the valves function & location,etc

The fact you have a code don't mean the part is bad

It may well be,but the evap system has to be tested & the
valve component tested & fail to need replacement

Nothing to do with starting

It opens to pull fuel tank fumes into the engine & burn them
based on computer strategy

If it is stuck open then you get unmetered air into the motor &
it can effect your fuel trim & cylinder firing

What does code p0203 mean for bmw 318i

Nr 3 injector faulty or open circuit to nr 3 injector. You could swap injector to another cylinder, clear the code & see if the code changes to another cylinder (PO201 nr 1, PO202 nr2 etc) then you know the injector is faulty or you could just replace & clear & see how you go. Most likly cause is the injector.
