Test 5B: No Response From Anti-Lock Brake Controller Module
NOTE:
For connector terminal identification and wiring diagrams, see
BODY CONTROL COMPUTER - INTRODUCTION article. Perform VERIFICATION TEST VER-1
after each repair.
CAUTION:
Always turn ignition off prior to disconnecting any module connector.
- Inspect fuse "K" in Power Distribution Center (PDC). PDC is located in engine compartment. If fuse is okay, repair open Red/Dark Green wire between PDC and anti-lock brake controller module 25-pin connector. If fuse is blown, go to next step.
- Using external ohmmeter, measure resistance between battery ground and PDC fuse "K" (Red/Dark Green wire). If resistance is less than 20 ohms, repair Red/Dark Green wire for short to ground. If resistance is 20 ohms or more, replace fuse.
