Pinpoint Test A: No Communication With The TPMS Module/Unable To Enter Self-Test

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

Test A1 - A2:

Normal Operation
The TPMS module requires an operating voltage in a range between 10 and 17 volts.

Voltage is supplied by circuit 1002 (BK/PK) (ignition feed) and circuit 3049 (BK/LG) (B+ voltage at all times). Ground is provided through circuit 57 (BK).

Possible Causes
- Power supply circuit 1002 (BK/PK) (ignition feed)
- Power circuit 3049 (BK/LG) (B+ voltage at all times)
- Ground circuit 57 (BK)
- TPMS module Scan tool
- Data Link Connector (DLC) and wiring
