Re: how to retrieve trouble codes on 91 loyale wagon
Mil is the malfunstion indicator lamp (check engine light) there is a connector either under the dash or under the hood near firewall that is normally not plugged in to anything. Use a paperclip to jumper this and the engine light will flash codes. i think the connector is green but check a repair manual to be sure. there are other connectors that you don't want to mess with by accident

Hi Pegrim, I believe on that vehicle year, the system is probably OBD1 You would do better to have a diagnostic check carried out on the computer. If you need the pin outs let us know the make model and year of manufacture of the vehicle and if it is petrol or diesel? In fact as much info as you can manage. Regards John
Diagnostic Test Code (DTC) P0700 is an informational code that is stored in the Engine Control Module (ECM) That informs the diagnostic technician that there are codes present in the Transmission Control Module (TCM) and that the TCM has requested the Malfunction Indicator Lamp (MIL) (AKA - Check Engine Light) to be turned on. This is because the MIL is controlled by the ECM and cannot be turned on directly by the TCM. So, the TCM requests the ECM to turn the light on. To find out the nature of the failure that caused the P0700, one must scan the TCM to retrieve the fault codes stored there. Please note that MOST generic OBD code readers cannot access the TCM - this is the reason for the P0700 code to set in the ECM (to alert somebody with a generic code reader that further diagnosis is needed for the TCM).
if your engine is running different then before the check light came on. have your computer system checked for error codes. start there. or your owners manual. or a service manual at your local auto store.
Older cars used the OBD 1 system for retrieving codes, check your owners man, for the location of the diagnostic connector under the hood, use a compatible scanner, most newer scanner's have the cable needed for making the connection. Good luck!
There is NO SUCH CODE as P1520... However, there is a Code as P1529 - TCM MIL request to
ECM This is a transmission trouble code.
Whenever the 'CHECK ENGINE' light comes on, the ECU (Engine Control Unit) sets a Diagnostic Trouble Code (DTC). These codes identify the particular engine management system which caused the light to come on. You'll need to use/find an OBDII (On-Board Diagnostic) Scanner to retrieve any code which have been stored in the ECU computer. Afterward, we might be able to help you DIAGNOSE and perhaps eventually fix the problem.
the regulator is in the alternator. it sounds like it isn't charging the battery anymore. battery voltage should be around 14 volts with engine running. also check connections at alternator to battery. have seen corrosion here keep the battery from charging
