STEP 4. Measure the voltage at the steering wheel sensor connector.
(1) Disconnect the steering wheel sensor connector.
(2) Ignition switch: "ON"
(3) Measure the voltage between the IG terminal and body ground.OK: The voltage should measure approximately 12 volts (battery positive voltage)
Is the check result normal?
Go to Step 5. The power supply circuit may be open. Repair the wiring harness wires or connectors between the steering wheel sensor connector IG terminal and the junction block.
