GM TPMS Fault Diagnosis
TPMS replacement is called for when the TPMS fails due to mechanical or electrical failure, broken accelerometer, low TPMS battery power or blocked pressure port. One of the most common causes of failure is inappropriate handling during wheel or tire removal or servicing. The TPMS is an electronic component fitted as part of a heavyweight mechanical process.
Before attempting to replace a GM TPMS we advise the use of one our Bartec Wheelrite tools to establish the need for replacement and the nature of the fault. This may support a warranty claim but will also ensure that the dealer or tire shop is covered for liability claims. The legal position is that as soon as the dealer breaks down the wheel then he becomes liable and cannot allow the car to be driven away from his shop with the TPMS warning light still on. Many dealers have found that customers will not accept the costs for repair and may attribute any breakage to the dealer if there is no audit trail.
The Bartec tools offer the capability to carry out a TPMS audit of the car and then show the customer the audit results from the screen or download them to a PC and print the audit results to show to the customer so that a cost can be agreed and the go ahead given before work commences. It is important to have a tool which can distinguish the correct TPMS in order to avoid picking up the transmission of other TPMS sensors, key fobs etc. It is important to limit your liability for any problems which occur.
The TPMS tool should be able to decode the transmission from the sensor and display the data. This will enable the technician to establish if the sensor has failed or is not fitted, whether the pressure port on the sensor is blocked, where the part is running at too high a temperature and other diagnostic information which might be included in the specific sensor (e.g. if there is a low battery condition on the TPMS). The direct TPMS will be attached to the back of the tire valve.
