Signal Circuit Inspection
WARNING: This page is about a different variant/trim than selected.
■ Check for short to ground in signal circuit
- Ignition "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 the specification?
YES
- Go to next step as below.
NO
- Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
■ Check for short to battery in signal circuit
- Ignition "ON" & Engine "OFF"
- Measure voltage between Vehicle speed input terminal of PCM harness connector and chassis ground
Specification: Approx. 0V
- Is voltage within the specification?
YES
- Go to next step as below.
NO
- Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
■ Check for open in signal circuit
- Ignition "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. 0Ω
- Is voltage 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.
