General Information - Diagnostic Trouble Code (DTC) Index DTC: Tire
Pressure Monitoring System Module (TPM)
Description and Operation

Tire Pressure Monitoring System (TPM)


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault and may also cause additional faults in the vehicle being checked and/or the donor vehicle.
NOTES:


If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
Warranty Policy and Procedures manual, or determine if any prior approval programme is in operation, prior to the installation
of a new module/component.


Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to
the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the
manufacturer approved diagnostic system).


When performing voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal places,
and with an up-to-date calibration certificate. When testing resistance, always take the resistance of the DMM leads into
account.


Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.


If DTCs are recorded and, after performing the pinpoint tests a fault is not present, an intermittent concern may be the
cause. Always check for loose connections and corroded terminals.


Where an 'on demand self-test' is referred to, this can be accessed via the 'DTC Monitor' tab on the manufacturers
approved diagnostic system.


Check DDW for open campaigns. Refer to the corresponding bulletins and SSMs which may be valid for the specific
customer complaint and carry out the recommendations as required.

The table below lists all Diagnostic Trouble Codes (DTCs) that could be logged in the Tire Pressure Monitoring System, for
additional Diagnosis and Testing information refer to the relevant Diagnosis and Testing Section.
