Component Inspection
Component Inspection
1. With ignition "OFF", reconnect the switch and ECM connectors
2. Ignition "ON" & Engine "ON".
3. Measure voltage between terminal 1 (back probe) of the switch harness connector and chassis ground.
A. Specification: Approx. B+
- Signal "OFF" (Steering wheel = Straight ahead) : Approx. B+
- Signal "ON" (Steering wheel = Turned) : Approx. 0V
4. Is voltage within the specification ?
YES
1) Check for poor connection between ECM 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
1) Substitute with a known-good sensor and check for proper operation. If the problem is corrected, replace sensor and then go to "Verification of Vehicle Repair" procedure.
