Service Procedure
Section 1.0: Read Sensor Test
Before servicing the tires/wheels, using your
TPMS TOOL
,
trigger each of the vehicle's sensors to make sure they are
working properly.
This will eliminate the liability associated with replacing
previously damaged or defective sensors. This procedure will
not change the vehicle settings because the vehicle has yet to
be put into learn/retraining mode.
This procedure allows you to quickly identify damaged or defective sensors, because some
vehicles do not report a damaged or defective sensor condition on the instrument cluster for up to
20 minutes.
Note: If the sensors do not trigger, please refer to the Troubleshooting section of this Guide.
Perform tire/wheel service.
For vehicles that require retraining, please see Section 2.0
Section 2.0: Learning the TPM System
Based on the Make-Model-Year of the vehicle, the tool informs
which relearn procedure is required: Auto, Manual or OBDII
relearn procedure.
For Manual and OBD relearn procedures, follow the instructions
on the tool screen. See paragraph 2 "Service TPMS" menu for
more information.
For vehicles with Auto relearn procedure, where the ECU is automatically
reset when driving the car, it is recommended to trigger each wheel
sensor, one final time, to make sure they are in correct working order prior
to releasing the vehicle to the customer.
