Tire Pressure Warning System
REGISTRATION1. REGISTER TRANSMITTER ID
NOTE: It is necessary to register the transmitter ID in the tire pressure monitor ECU when replacing the tire pressure monitor valve sub-assy and/or tire pressure monitor ECU.
a. Set the tire pressure of all wheels to the specified value.
b. Connect the hand-held tester to DLC3.
c. Turn the ignition switch to the ON position.
d. Read and write down the ID by using the DATA LIST.
e. Select the registration mode "MAIN".
f. Input the ID using the hand-held tester and transmit it to the tire pressure monitor ECU.
g. Set the ID transmission condition to "COMPLETE".
HINT: If the operation of step (d) to (f) does not complete within 5 min., the mode will return to the normal operation mode.
2. CONFIRMATION OF TRANSMITTER ID REGISTRATION
a. Set the tire pressure of all wheels to the specified value.
b. Connect the hand-held tester to DLC3.
c. Turn the ignition switch to the ON position.
d. Select the "SIGNAL CHECK" mode on the hand-held tester.
e. Forcibly transmit the transmitter IDs for all wheels.
HINT:
- The transmitter ID can be transmitted by rapidly reducing the tire air pressure.
- When rapidly reducing the pressure, loosen the valve core.
f. Check that test mode DTCs C2181/81, C2182/82, C2183/83, C2184/84 and C2185/85 are all erased.
HINT: If they haven't been erased, reset the tire pressure to the specified value and rotate the tire 90 to 270 degrees. Then forcibly transmit the transmitter IDs of all wheels. If they are still output, register the transmitter IDs.
g. Set the tire pressure of all wheels to the specified value.
