NOTE: Ford DOES NOT provide procedures to retrieve or clear trouble codes without the Super Star II tester. The anti-lock brake/traction assist system has on-board diagnostic capabilities. However, the module as received from manufacturing is equipped with a stored error code (61). This will affect the service procedure. The error codes can be retrieved from the ABS module in the following manner. 1. 2. 3. 4. Connect Super STAR II tester to connector located in engine compartment on the power distribution box. Turn on Super STAR II tester and latch button down in TEST position. Turn ignition switch to RUN position. Read first code output. After approximately 15 seconds, the next code will be output. Leave button latched until all codes are output. NOTE: Make sure that all codes are written down. 5. The diagnostic procedure should be as follows provided that the CHECK ANTI-LOCK BRAKE indicator stays on all the time or flashes intermittently. NOTE: If the BRAKE warning indicator is on or intermittently comes on, refer to the Warning Indicator Symptom Chart. NOTE: If there are more codes stored in the anti-lock brake control module memory, no codes will erase until all codes have been output by the Super STAR II tester, all malfunctions have been serviced and the vehicle is driven about 40 km/h (25 mph). This means that if a 20s code originally existed and was serviced, it can be ignored when running the on-board diagnostic the second time. If the first code received is 18, 19 or in the 20s and no other code is received, service the indicated component. No other codes can be output if a 20s code exists. After servicing the indicated 18, 19, or 20s code, repeat the procedure for retrieving error codes. 6. If a code 61 is received with any other code, ignore the code 61 and service the other indicated components. If, after correcting all other indicated malfunctions, the CHECK ANTI-LOCK BRAKE indicator is still on, service the Fluid Level Switch (FLS) circuit. 7. If a code 61 is received and no other codes are received, service the FLS circuit. 8. If no code, or only a code 10 is received, use the Anti-Lock Quick Check Sheet since some possibilities are not recognized and retained in the anti-lock brake control module memory. See: Trouble Code Descriptions/Quick Check Sheet 9. When dealing with intermittent ABS warning light ON concern, make certain to visually inspect all wiring related to the component associated with the code received.

Some control modules don’t have a serial link. To read the fault code, you will have a to use a different method. Bridge pin A and B in the diagnostic connector Turn the ignition on Count flashes in the check engine lamp Translate them using the list below To erase the fault code disconnect the battery for 30 seconds Blink code interpretation The code read out always starts with “Code 12” repeated three times, the fault codes are flashed. All codes are repeated three times, the first digit is flashed with a space of 0.4 seconds, then there is a 1.2 second delay until the second digit is flashed. The delay between codes is 3.2 seconds. The sequence is ended by once again flashing of “Code 12” three times.

Service Engine Soon (SES) Light On, Diagnostic Trouble Code (DTC) P0741, Torque Converter Clutch (TCC) Excessive Slip, Transaxle Chuggle, Slip/Surge (Inspect and/or Replace Various Internal Transaxle Components) 1998-2002 Cadillac Eldorado 1998-2004 Cadillac Seville 1999-2004 Cadillac DeVille 2000-2003 Oldsmobile Aurora with 4T80-E Auto Transaxle (RPO MH1) Some customer may comment on the SES light on and a chuggle or surge. Diagnostics may show excessive TCC slip speed and DTC P0741 will be current code Seal damage may allow the TCC apply fluid to leak into the channel plate, causing excessive TCC slippage under certain conditions, eventually causing no TCC apply.

CAUTION: To prevent possible Electrostatic Discharge damage to the Powertrain Control Module (PCM), Do Not touch the connector pins or soldered components on the circuit. Service of the PCM should normally consist of either replacement of the PCM or a Programmable Read Only Memory (PROM) change. If the diagnostic procedures call for the PCM to be replaced, the engine calibrator (PROM) and PCM should be checked first to see if they are the correct parts. If they are remove the PROM from the faulty PCM and install it in the new service PCM. THE SERVICE PCM WILL NOT CONTAIN A PROM. Diagnostic Trouble Code (DTC) 51 indicates the PROM is installed improperly or has malfunctioned. When DTC 51 is obtained, check the PROM installation for bent pins or pins not fully seated in the socket. If the PROM is installed correctly and DTC 51 still shows, replace the PROM. Important: When replacing the production PCM with a service PCM (controller), it is important to transfer the Broadcast code and production PCM number to the service PCM label. Please do not record on PCM cover. This will allow positive identification of PCM parts throughout the service life of the vehicle. CAUTION: To prevent internal PCM damage, the ignition must be “OFF” when disconnecting or reconnecting power to PCM (for example, battery cable, PCM pigtail, PCM fuse, jumper cables, etc.). REMOVE OR DISCONNECT 1. Negative battery cable. 2. Right side sound insulator. 3. Vacuum center. 4. Connectors to PCM. 5. PCM. 6. PROM access cover. 7. PROM from PCM. INSTALL OR CONNECT 1. PROM to PCM. 2. PROM access cover. 3. PCM. 4. Connectors to PCM. 5. Vacuum center. 6. Right side sound insulator. 7. Negative battery cable.
