Service Procedure
NOTE:wiTECH must be used to perform this recall. This procedure must be performed with software release level 12.02 or higher. If the programming for the TPM System is aborted or interrupted, repeat the procedure.
Program the TPM System:
1. Open the hood. Install a battery charger and verify that the charging rate provides 13.0 to 13.5 volts. Do not allow the charger to time out during the programming process. Set the battery charger timer (if so equipped) to continuous charge.
NOTE:
Use an accurate stand alone voltmeter. The battery charger voltmeter may not be sufficiently accurate. Voltages outside of the specified range will cause the programming to be unsuccessful. If voltage reading is too high, apply an electrical load by activating the park or headlamps and/or HVAC blower motor to lower the voltage.
