On-Board Diagnostics
On-Board Diagnostics Tools Required:- Rotunda SUPER STAR II Tester 007-0041 B
NOTE: Ford DOES NOT provide procedures other than those described to retrieve or clear trouble codes.
The anti-lock brake/traction assist system (ABS) module is capable of performing a an on-board diagnostic using Rotunda SUPER STAR II Tester 007-0041B or equivalent.
If the SUPER STAR II Tester is not available, the Anti-Lock Quick Check Sheet should be used.
Pinout Values and Diagnostic Parameters
The anti-lock brake/traction assist control module monitors system operation and can store all defined diagnostic trouble codes in its memory. It is important to understand that the ABS module CANNOT recognize some failures, therefore if a symptom exists and no diagnostic trouble codes are stored by the ABS module, other diagnostic steps must be followed.
The module cannot store a diagnostic trouble if there is no power to the module. This condition can be found by using the Quick Check Sheet.Pinout Values and Diagnostic Parameters
Codes 18, 19 and 20 will override any other stored code and will not allow other codes to be output if the failure exists while the on-board diagnostic is being run. If the failure is intermittent or if the code was left in the ABS module due to improper erasing procedures, the code will be output during on-board diagnostic but the next code will also be output.
STAR Tester Connection and Battery Check
1. Turn ignition switch to OFF position.
2. Locate SUPER STAR II Tester connector in engine compartment on RH shock tower.
3. Connect SUPER STAR II Tester connector to vehicle connector.
NOTE: Only one multi-pin connector is used.
4. Turn on power switch on RH side of SUPER STAR II Tester. A steady 00 or blank screen will appear to signify that SUPER STAR II Tester is ready to start on-board diagnostic and receive Diagnostic Trouble Codes (DTCs).
NOTE: If the message LO BAT appears in upper LH corner of read-out display and stays on, replace SUPER STAR II Tester's 9-volt battery before continuing with on-board diagnostic. The message LO BAT will appear momentarily when power switch is turned off.
5. With ignition still OFF, push SELF-TEST button in center of SUPER STAR II Tester.
6. Push SELF-TEST button again. This deactivates sequence.
7. If SUPER STAR II tester passes above test (00 or blank screen with button in TEST position), proceed with On-Board diagnostic procedure. If any DTCs appear during on-board diagnostic refer to the On-Board diagnostic Trouble Code Index.Diagnostic Trouble Code (DTC) Index
On-Board Diagnostic Procedure
The anti-lock brake/traction assist system has self-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. Connect SUPER STAR tester to connector located in engine compartment.
2. Turn on SUPER STAR II tester and latch button down in TEST position.
3. GTurn ignition switch to RUN position.
4. 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.
The diagnostic procedure should be as follows providing 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.Symptom Related Diagnostic Procedures
1. 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 18,19 or 20's DTC exists. After servicing the indicated 18,19 or 20s code, repeat the procedure for retrieving error codes.
NOTE: If there are more codes stored in the ABS 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 18,19 or 20s code originally existed and was serviced, it can be ignored when running the on-board diagnostic the second time.
2. If a Code 61 is received with any other code, ignore the Code 61 and service the other indicated malfunctions. If after correcting all other indicated malfunctions, the CHECK ANTI-LOCK BRAKE indicator is still on, service the FLS circuit.
3. If a Code 61 is received and no other DTCs are received, service the FLS circuit.
4. If no code, or only a Code 10 is received, use the Anti-Lock Quick Check Sheet in the diagnostic manual since some possibilities are not recognized and retained in the ABS module memory.
