TPMS Diagnostic Chart
CAUTION:
^ Do NOT remove the Long Term Storage Fuse unless the ignition key is inserted in the ignition switch.
^ If the storage fuse is removed without the ignition key in the switch, the engine will not start.
^ To correct this condition if it occurs, first insert the fuse, then insert the key in the ignition switch.
^ See the Service Manual for more information.
IMPORTANT INFORMATION:
I.D. Registration:
310
^ This process informs or tell the control unit of each wheel transmitter's location (i.e. LF, RF, RR, and LR).
^ Reason: The control unit must know the location of each transmitter in order to correctly relay (send) pressure information about each tire/wheel.
Transmitter "Wake Up" Activation:
^ Turns on ("Wakes Up" each wheel transmitter allowing it to send pressure information to the control unit.
The chart shows some conditions which may require I.D. Registration and/or Transmitter "Wake Up" Activation.
NOTES:
1) In the case of a low tire pressure condition the TPMS warning light will come on. To turn the light OFF do the following:
^ Pump up the tire pressure to the correct setting.
^ Drive the vehicle over 20 MPH for several minutes.
2) Tire pressure signals from the wheel transmitters are updated by the control unit as follows:
Vehicle parked with ignition switch ON
^ Pressure information updated every hour*
Vehicle driven over 20 MPH
^ Pressure information updated every minute*
* When the ignition is first turned "ON", CONSULT-II will indicate "0" pressure and will not give an update for 1 hour. To save time
drive the vehicle over 20 MPH for a few minutes. The pressure information will then be updated.
SERVICE PROCEDURE
Wheel Transmitter Activation ("Wake Up") Procedure
This procedure must be performed using the TPMS Initialization Tool # J-45295.
