Signal Circuit Inspection

WARNING: This page is about a different variant/trim than selected.

■ Check for short to ground in signal circuit

IG "OFF".
Disconnect PCM and ABS Control Module connectors
Measure resistance between Vehicle speed input terminal of PCM harness connector and chassis ground.
Specification: Infinite
Is resistance within specification?
YES
- Go to next step below.
NO
- Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.

■ Check for short to battery in signal circuit

IG "ON".
Measure voltage between Vehicle speed input terminal of PCM harness connector and chassis ground
Specification: Approx. 0 V
Is voltage within the specification?
YES
- Go to next step below.
NO
- Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.

■ Check for open in signal circuit

IG "OFF".
Measure resistance between Vehicle speed input terminal of PCM harness connector and Vehicle speed output terminal of ABS/ESP Control Module harness connector.
Specification: Approx. 0 Ω
Is resistance within the specification?
YES
- Check for poor connection between PCM and component: backed out terminal, improper mating, broken locks or poor terminal to wire connection. Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NO
- Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
