Code S073, Right Rear Accelerometer Fault: Description

The RSS module monitors the accelerometer data for a sensor out-of-range condition. If the signal is under voltage (0.5 volt) or over voltage (4.5 volts) for more than 1/2 second at vehicle speeds greater than the full firm speed setting, the error is set.

1. To diagnose this condition, clear codes. Enter output cycling. Manipulate affected wiring. Tap the sensor. Recheck for codes. See NOTES ON INTERMITTENTS  under TESTING & DIAGNOSIS.
2. The code may set because Code S077 is set. If Code S077 is set, first diagnose and repair fault causing Code S077.
