Circuit/System Testing
1. Verify that DTC C0710 is not set.
瀚慖f the DTC is set, refer to DTC C0710 (See: C Code Charts/C0710/Antilock Brake System - Non-Hybrid Less than 3900 kg (8600 lb)
GVW).
2. Ignition OFF, disconnect the harness connector at the yaw/lateral accelerometer sensor.
3. Ignition OFF and all vehicle systems OFF. It may take up to 2 minutes for all vehicle systems to power down. Test for less than 10 ohm
between the ground circuit terminal 1 and ground.
瀚慖f greater than the specified range, test the ground circuit for an open/high resistance.
4. Disconnect the harness connector at the EBCM.
5. Test for infinite resistance between the 12 V reference circuit terminal 32 of the EBCM connector and ground.
瀚慖f not the specified value, test the 12 V reference circuit for a short to ground.
6. Test for less than 2 ohm between the 12 V reference circuit terminal 32 of the EBCM connector and terminal 4 of the yaw/lateral
accelerometer sensor connector.
瀚慖f greater than the specified range, test the 12 V reference circuit for open/high resistance.
7. If all circuits test normal, replace the yaw/lateral accelerometer sensor. If the DTC resets, replace the EBCM.
