Communication with the TPMS Control Unit
(TPMS Message) (’08-09 models)
NOTE: If you are troubleshooting multiple DTCs, be
sure to follow the instructions in B-CAN System
Diagnosis Test Mode A (see page 22-93).
1. Clear the DTCs with the HDS.
2. Turn the ignition switch to LOCK (0) and then back to ON (II).
3. Check for the DTCs with the HDS.
Go to step 4.
Intermittent failure, the F-CAN
communication line is OK at this time. Check for
loose or poor connections. If the connections are
good, check the battery condition (see page 22-67),
and the charging system.
4. Check for DTCs in the TPMS.
Troubleshoot the TPMS DTCs with the
HDS.
Go to step 5.
5. Turn the ignition switch to LOCK (0).
6. Disconnect the gauge control module (tach) 36P connector.
7. Disconnect the TPMS control unit 20P connector. 8. Check for continuity between gauge control
module (tach) 36P connector terminals No. 1 and
No. 19 and TPMS control unit 20P connector
terminals No. 2 and No. 11 respectively.
Go to step 9.
Repair an open in the wire between the gauge
control module and the TPMS control unit.
9. Check for poor connections, power, and ground to the TPMS control unit. If OK, substitute a known-
good TPMS control unit.
10. Check for DTCs with the HDS.
Replace the gauge control module (tach)
(see page 22-277).
Replace the original TPMS control unit.
