Code 76 - Lateral Accelerometer Signal (2 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. 7)  Checks for correct signal voltage for a full, hard right turn. Full right-hand turn is simulated by exposing left side of accelerometer to gravity force of one G (standing accelerometer on end).
2. 8)  Checks for reset of code after inspecting most of system.
3. 9)  Checks if Code 76 reset in step 8) is caused by lateral accelerometer. When road testing vehicle, DO NOT make any severe turns that may cause Tech 1 "Scan" tester to trigger code because of spiking signal from lateral accelerometer.
4. 10)  If lateral accelerometer was replaced in step 6), EBCM is most likely at fault. If accelerometer was not replaced in step 6), it should be replaced before continuing diagnosis.
5. 11)  Checks for code reset during road test. If code continues to reset, EBCM is detecting a fault when one does not exist.
