WIRING DIAGRAM
INSPECTION PROCEDURE
Note
When replacing the tire pressure warning ECU and receiver, read the transmitter IDs stored in the old ECU using the GTS and write them down before removal.
It is necessary to perform initialization Click here after registration Click here of the transmitter IDs into the tire pressure warning ECU and receiver if the ECU has been replaced.
PROCEDURE
CHECK HARNESS AND CONNECTOR (TIRE PRESSURE WARNING ECU AND RECEIVER - TIRE PRESSURE WARNING ANTENNA)
| *a | Front view of wire harness connector (to Tire Pressure Warning ECU and Receiver) |
| *b | Front view of wire harness connector (to Tire Pressure Warning Antenna) |
| *c | Shielded wire |
Disconnect the F118 tire pressure warning ECU and receiver connector.
Disconnect the P73 tire pressure warning antenna connector.
Measure the resistance according to the value(s) in the table below.
Tech Tips
Because the coaxial cable that is used for the tire pressure warning antenna consists of a center conductor and an outer shielding layer (-), this measurement should be performed to ensure that there is no malfunction in the coaxial cable.

Tech Tips
*1: It may take a few minutes until the values are displayed.
*2: w/ Spare Tire
Rapidly reduce the tire pressure for each wheel at least 40 kPa (0.4 kgf/cm2, 5.8 psi) within 30 seconds.
Check that each "ID Tire Inflation Pressure" value displayed on the GTS has changed.
