Complaint:
Customer may complain of unusual handling characteristics caused by random sprung mass vibrations.
Cause:
Acceleration sensors may have been installed which could cause fault codes to be stored or unusual handling characteristics to occur. See the label on the sensor in the attachment.
Remedy:
1. Read out the fault code. If a fault code is displayed, replace only the affected acceleration sensor.
2. If complaint persists, change both acceleration sensors at the front axle and check the handling characteristics. If
complaints persists, replace the acceleration sensor at the rear axle.
