CAUTION: The Flex Probe Kit must be used for all test connections. Use of standard multimeter probes may damage wiring terminals.

Normal Operation
The TPMS module requires an operating voltage in a range between 10 and 17 volts.
Voltage is supplied by circuit 1050 (LG/VT) (ignition feed) and circuit 1003 (GY/YE) (B+ voltage at all times). Ground is provided through circuit 1205 (BK).

Possible Causes
- Power supply circuit 1050 (LG/VT) (ignition feed)
- Power circuit 1003 (GY/YE) (B+ voltage at all times)
- Ground circuit 1205 (BK)
- TPMS module
- Diagnostic tool
- Data link connector (DLC) and wiring
