When you’re driving along and the traction control light comes on you might think that’s where the problem lies. But some vehicles use one warning light for multiple systems. Follow this Real Fix to see how a problem with the AWD system on a BMW X3 was diagnosed and repaired.
2008 BMW X3 30i 3.0L
5462, 5F3A, Replaced Transfer Case Shift Motor
The customer states the traction control system light is on.
Connected a scan tool and found codes: 5462 – Error Actuator Or Increased Power Requirements For Clutch and 5F3A – Clutch Gearbox-ECU: Clutch Is Open Rear Wheel Drive. With the engine at idle, monitored live scan tool data while shifting the transfer case from two wheel drive to four wheel drive and found the transfer case position was fixed. Inspected the transfer case shift motor wiring harness and connector and detcted no obvious faults. With the ignition on and the engine off, used a multi-meter to check for the presence of voltage and ground at the transfer case shift motor connector and found both were present. Removed the transfer case shift motor and a visual inspection revealed the motor was damaged.
Replaced the transfer case shift motor, cleared codes, performed a road test and verified the vehicle operated properly.
