Guest AlvinL Posted April 20, 2006 Report Share Posted April 20, 2006 1993 to 1995 850's have the diagnostic connector beside the windshield washer fill. Click and read the Bay 13 link on how to read the 1993 to 1995 Diagnostic Connectors Check Engine codes and how to clear them. THE USE OF THE FOLLOWING INFORMATION IS ENTIRELY AT THE USERS RISK To retrieve the flash codes the following procedure can be adopted: Connect an LED, with the correct polarity, in series with a 1k8 ohm resistor, between pin 16 (+) and pin X, where X is the pin corresponding with the module to be read. Connect a push to make switch between pin X and pins 4 or 5 (-). The circuit can then be used in the same way as the pre '96 diagnostic sockets, situated in the engine compartment. For: Motronic 4.3 or Fenix 5.2, X = 3. ECC , X = 6, Timer Type 4, X = 9. Cruise Control, X = 13; 900 & S/V 90 ABS, X = 12 . What the codes mean: A1: Transmission 111 No faults found 112 Solenoid S1 short circuit to battery voltage 113 Transmission control module (TCM) fault 114 Program selector open circuit or short circuit to supply 121 Solenoid S1 short circuit to ground or control module fault 122 Solenoid S1 open circuit 123 Solenoid STH short circuit to battery voltage 124 Mode selector faulty or short circuit to ground 131 Solenoid STH open/short circuit or control module fault 132 Transmission control module(TCM) fault 134 Faulty load signal from ignition control module 141 Oil temperature sensor short circuit to ground 142 Oil temperature sensor open circuit 143 Kickdown switch faulty or short to ground 211 Transmission control module (TCM) fault 212 S2 solenoid short circuit to battery 213 Throttle position (TPS) signal too high 221 S2 solenoid short circuit to ground or control module fault 222 S2 solenoid open circuit 223 Throttle position (TPS) sensor signal too low 231 Throttle position (TPS) sensor sporadic 232 Speedometer signal missing 233 Incorrect speedometer signal 235 High Oil temperature 245 Open or short in Torque limiting circuit 311 RPM signal from transmission missing 312 RPM signal from transmission faulty 313 Faulty signal from gear position sensor (PNP) 321 Shift time too long 322 Incorrect gear ratio 323 Lock up slips or is not engaged 331 Short circuit to battery in SL circuit 332 SL solenoid open or control module fault 333 SL solenoid short or control module fault A2: Fuel System 111 No faults detected 112 Fault in ECM 113 Short term fuel mixture too weak 115 Injector 1 121 MAF sensor signal 123 ECT signal 125 Injector 2 131 RPM sensor signal missing 132 Battery voltage 135 Injector 3 143 Front knock sensor signal 145 Injector 4 153; 153 Rear HO2S signal 154 EGR system leakage 155 Injector 5 212 Front HO2S signal 214 RPM sensor signal sporadic 223 IAC valve opening signal 225 A/C pressure sensor signal 231 Long term fuel trim, part load 232 Long term fuel trim, idling 233 Long term idle air trim 241 EGR system flow malfunction 245 IAC valve closing signal 311 VSS signal 314 CMP sensor signal 315 EVAP system 325 Memory failure 335 Request for MIL lighting from TCM 411 TP sensor signal 413 EGR temp sensor signal 414 Boost pressure regulation 416 Boost pressure reduction from TCM 425 Rear HO2S sensor control faulty 432 Temperature warning level 1 433 Rear knock sensor signal 435; 435 Front HO2S slow response 436, 436 Rear HO2S compensation 443 Three way cat.
