Circuit/System Testing

Ignition ON, observe the ABS DTCS function in EBCM VSES scan tool data display.

1. Ignition OFF, disconnect the yaw rate and lateral acceleration sensor connector.
2. Ignition OFF, test for less than 1 ohm of resistance between the low reference circuit terminal 6 and ground.
   • If greater than 1 ohm, test the low reference circuit terminal 6 and the EBCM ground circuit terminal 25 (JL4) terminal 45 (without JL4) for an open/high resistance. If the circuits test normal, replace the EBCM.
3. Test the lateral accelerometer 12-volt reference circuit terminal 1, for an open/high resistance or a short to voltage or ground.
   • If all circuits test normal, replace the yaw rate sensor/lateral acceleration sensor, and clear the yaw rate sensor offset value in the EBCM.
   • If the DTC sets again after replacing the yaw rate sensor/lateral acceleration sensor, replace the EBCM.
