Circuit/System Testing

C0196 00

1. Ignition OFF, disconnect the yaw rate sensor/lateral accelerometer connector.
2. Ignition OFF, test for less than 1.0 ohm of resistance between the low reference circuit and ground.
   • If greater than 1.0 ohm, test the low reference circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the EBCM.
3. Ignition ON, connect a 3-amp fused jumper wire between the 5-volt reference circuit and the yaw rate sensor signal circuit of the connector. Ignition ON, with the scan tool, verify yaw rate sensor signal parameter is 4.8-5.2 volts.
   • If over 5.2 volts, test yaw rate sensor signal circuit for short to voltage. If the circuits tests normal, replace the EBCM.
   • If under 4.8 volts, test yaw rate sensor signal circuit for open/high resistance or short to ground. If the circuits tests normal, replace the EBCM.
4. If all circuits test normal replace the yaw rate sensor/lateral accelerometer.

C0196 28

1. Ignition OFF, disconnect the yaw rate sensor/lateral accelerometer connector and EBCM connector.
2. Test for infinite resistance between the yaw rate frequency circuit and ground.
   • If less than infinite resistance, test the yaw rate frequency circuit for a short to ground.
3. Test for less than 1.0 ohm of resistance on the yaw rate frequency circuit between the yaw rate sensor/lateral accelerometer connector and EBCM connector.
   • If greater than 1.0 ohm, test the yaw rate frequency circuit for an open/high resistance.
4. Replace yaw rate sensor/lateral accelerometer. If C0196 28 is still current replace EBCM.
