Is the DTC active at this time?
Yes
- Go to Test Step 2
No
- Perform the ABS Intermittent Condition Test. Refer to Brake System .
Test Step 2 - CHECK IF TOTALLY INTEGRATED POWER MODULE (TIPM) CAN BUS DTCS ARE PRESENT
- With the scan tool, read the TIPM DTCs.
Are there any TIPM CAN BUS DTCs present?
Yes
- Perform the appropriate diagnostic procedures.
- Perform the ABS Verification Test. Refer to Brake System .
No
- Using the schematics as a guide, check the Anti-Lock Brake System (ABS) Module pins, terminals, and connectors for corrosion, damage, or terminal push out. Pay particular attention to all power and ground circuits. If no problems are found, replace the Anti-Lock Brake Module. Refer to Removal and Installation .
