Hello, I own a 2001 Chev Suburban LT HD 8.1 L engine 4x4 with Auto Ride. The RPO code is Z55. The message center is indicating " Service Ride Control". I have taken the vehicle into a GM dealer and they ran a diagnostic on the system and the result was a C0625, left rear position sensor malfunction. The wiring is okay at time of servicing. The Auto Ride system has a sensor at each wheel. GM does not make or sell this beforementioned sensor any more. I like the Auto Ride system because of the excellent real time damping which uses a Suspension Control Module and measures the body roll and suspension movement . I am asking if anyone knows of an After Market parts supplier who might have this sensor in inventory? I have already investigated the removing of all sensors, install a bypass module and regular shocks.
