Circuit/System Testing
- Ignition OFF, disconnect the yaw rate sensor/lateral accelerometer and the steering wheel position sensor connectors.
- Ignition ON, measure for 4.8-5.2 volts at each 5-volt reference circuits and ground.
- If over 5.2 volts, test each 5-volt reference circuit for a short to voltage. If the circuits tests normal, replace the EBCM.
- If under 4.8 volts, test each 5-volt reference circuit for short to ground. If the circuits tests normal, replace the EBCM.
