Accessing Abs Codes
- Ensure ignition is off. Access 4-pin diagnostic connector located in rear wheel arch, next to ABS ECU. Connect jumper wire between Black wire terminal and Brown/Pink wire terminal in diagnostic connector. Turn ignition switch to ON position. Observe pulses of ANTI-LOCK warning light.
- Codes will be given in 2-digit numbers. After ignition is on for 6 seconds, first digit of code will be displayed followed by a short pause, and then second digit of code will be displayed. There will be a 6.5-second pause between codes. ECU is capable of displaying only one fault at a time. For example, Code 21 may be displayed but Code 22 will not display. ECU will show next fault; for example, Code 31 or greater. ANTI-LOCK light will illuminate without flashing when display of codes is complete.
- After completing necessary repairs, erase ABS codes. See ERASING ABS CODES. After erasing ABS codes, go to step 1) and access ABS codes to record any new or persistent faults.
- ABS codes beginning with 1, 2, 3, 4, 5 or 6 are considered high priority codes. High priority codes may affect vehicle braking performance and should be repaired immediately. ABS codes beginning with 7 are considered low priority codes. Low priority codes may or may not affect vehicle braking performance. See HIGH PRIORITY ABS CODES or LOW PRIORITY ABS CODES.
NOTE:
If repairs fail to remedy problem, replace ABS ECU. If ANTI-LOCK light stays on continuously without ABS codes being displayed, failure is probably in ABS ECU. Check power supply to ABS ECU before replacing ABS ECU.
