Circuit/System Verification 1. Ignition ON, observe the scan tool Lateral Accelerometer Signal parameter. The reading should be 2.3-2.7 volts. 2. Ignition ON, observe the scan tool Yaw Rate Sensor parameter. The reading should be 2.3- 2.7 volts. Circuit/System Testing 1. Ignition OFF, disconnect the harness connector at the yaw rate/lateral accelerometer. 2. Test for less than 2 ohms of resistance between the ground circuit terminal 1 and ground. If greater than the specified range, test the ground circuit for an open/high resistance. 3. Ignition ON, test for 11.8 - 12.2 volts between the 12-volt reference circuit terminal 4 and ground. If less than the specified range, test the 12-volt reference circuit for a short to ground 4. Test for 5.5-7.0 volts between the CAN circuit terminal 3 and ground. If greater than the specified range, test the CAN circuit for a short to voltage. If the If less than the specified range, test the CAN circuit for a short to ground or an 5. Test for 5.5-7.0 volts between the CAN circuit terminal 2 and ground. If greater than the specified range, test the CAN circuit for a short to voltage. If the If less than the specified range, test the CAN circuit for a short to ground or an 6. Test for infinite ohm of resistance between the CAN circuit High, and Low terminals 2 and 3. If less than the specified range, test the CAN circuits for a shorted to each other. If the 7. If all circuits test normal, test or replace the yaw rate/lateral accelerometer sensor. Repair Procedures Perform the Diagnostic Repair Verification after completing the diagnostic procedure. Control Module References for EBCM replacement, setup and programming
