Retrieving Codes (Using Anti-Lock Warning Light)
NOTE:
ABS Diagnostic Trouble Codes (DTC's) may also be retrieved using a scan tester. To retrieve ABS DTC's using scan tester, follow scan tester manufacturer's instruction manual.
- When ANTI-LOCK warning light remains on, EBCM will store DTC's and disable ABS system. If DTC's are not displayed, wiring harness from EBCM to ANTI-LOCK warning light (White wire) may be disconnected. Check and repair wire as necessary.
- Ensure ignition switch is in OFF position and brake pedal is released. Using jumper wire, connect terminals No. 1 and 3 of Data Link Connector (DLC). DLC is Orange and is located behind driver's side kick panel. See Fig 1 . Turn ignition switch to ON position. DTC will be displayed by flashing ANTI-LOCK warning light.
- A pause of 3.2 seconds exists between DTC's. A pause of 1.2 seconds exists between DTC numbers. DTC numbers will flash every .4 second. Count number of short flashes to determine existing DTC. DTC 12 will be displayed 3 times, then any other DTC's are also displayed 3 times.
- If no other DTC's have been stored, ABS warning light will repeat DTC 12. Up to 3 different DTC's can be stored, starting with most recent DTC. ANTI-LOCK warning light will discontinue displaying codes after 5 minutes. To identify DTC possible component or circuit malfunction, see ABS SELF-DIAGNOSTIC TROUBLE CODE IDENTIFICATION table.
