Code 76 - Lateral Accelerometer Signal (1 Of 2): Notes

Lateral accelerometer circuit provides signal reflecting severity of vehicle turn to EBCM. Information is used by EBCM to modify control of rear wheel brakes to help prevent loss of control in a turn because of light brake pedal pressure at speeds greater than 30 MPH.

Code 76 will be set when accelerometer signal is out of acceptable range for 7.5 minutes or longer.

1. Checks if another ABS/ASR system problem is causing Code 76.
2. Checks for correct accelerometer signal voltage in a no-turn condition.
3. Checks for correct accelerometer signal voltage at full left-hand turn. Full left-hand turn is simulated by exposing right side of accelerometer to gravity force of one G (standing accelerometer on end).
4. Checks for correct accelerometer signal voltage at a full right-hand turn. Full right-hand turn is simulated by exposing left side of accelerometer to gravity force of one G (standing accelerometer on end).
5. Checks connectors and wiring for intermittents and/or shorts.
6. Checks if Code 76 resets after replacing lateral accelerometer. If Code 76 resets after replacing lateral accelerometer, EBCM is interpreting a problem when it should not be. Continue diagnosis to determine faulty component or circuit.
