Diagnostic Procedures Overview

NOTE: Ford DOES NOT provide procedures to retrieve trouble codes without the Super Star II tester.

The anti-lock brake electronic control module is capable of performing a self-test using Rotunda Super Star II tester 007-00041 or equivalent. If the Super Star tester is not available, the anti-lock Quick Check sheet can be used as described.
The anti-lock control module monitors system operation and stores up all defined service codes in its memory. It is important to understand that the control module cannot recognize some failures therefore is a problem exists and no service codes are stored by the control module, other diagnostic steps must be followed. The module cannot store a service code if there is no power to the module. This fault code can be found by using Quick-Check Test.
A 20 series code will override any other stored code and will not allow other codes to be output if failure exists while the Self-Test is being run. If failure is intermitent or if code was left in the computer due to improper erasing procedures, the code will be output during Self-Test but the next code will also be output.
The anti-lock brake system has self-diagnostic capabilities, however the module as received from manufacturing is equipped with a stored error code 61. This will affect service procedure.
The error codes can be retrieved from the computer as follows:
1. Connect Super Star II tester to connector located in engine compartment.
2. Turn on Super Star II tester and latch button down in Test position.
3. Turn 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. Ensure all codes are written down.
If check Anti-Lock Brake warning lamp is on or intermittently comes on, refer to "Warning Lamp Diagnosis". The diagnostic procedure should be as follows:
1. If first code received is in the 20's and no other code is received, service the indicated fault. No other codes can output if a code 20's fault exists. After servicing the indicated 20's code, repeat procedure for retrieving error codes.
2. If there are more codes stored in the computer's memory, no codes will erase until all codes have been output by the Super Star Tester II, all faults have been serviced and the vehicle is driven about 25 mph. This means if a 20's code originally existed and was serviced, it can be ignored when running the Self-Test the second time.
3. If Code 61 is received with an other code, ignore code 61 and service other indicated faults. If after correcting all other indicated, the Check Anti-Lock Brake lamp is still on, service indicated Code 61 fault.
4. If no code, or only a Code 10 is received, use the Anti-Lock Quick Tests Checks since some faults are not recognized and retained in the computer memory.
