Pinpoint Test G: The Tire Pressure Monitoring System (TPMS) Does Not Enter Sensor Training Mode When Using the TPMS (Tire Pressure Monitoring System) Sensor Training Procedure
Normal Operation
For the Tire Pressure Monitoring System (TPMS) to enter TPMS (Tire Pressure Monitoring System) sensor training mode, the TPM (Tire Pressure Monitor) /VSM (Vehicle Security Module) must receive valid inputs from the stoplamp switch (OFF-ON-OFF) and it must receive valid Vehicle Speed Sensor (VSS) input (0 km/h [0 mph]). The TPM (Tire Pressure Monitor) /VSM (Vehicle Security Module) receives the brake pedal information from the Instrument Cluster (IC) and the VSS (Vehicle Speed Sensor) information from the IC (Instrument Cluster). TPM (Tire Pressure Monitor) /VSM (Vehicle Security Module) monitors the ignition switch status (both OFF and RUN). Refer to Tire Pressure Monitoring System (TPMS) Sensor Training .
This pinpoint test is intended to diagnose the following:
- Stoplamp switch concern
- Vehicle speed input concern
- TPM (Tire Pressure Monitor) /VSM (Vehicle Security Module)
PINPOINT TEST G : THE TPMS (Tire Pressure Monitoring System) DOES NOT ENTER SENSOR TRAINING MODE WHEN USING THE TPMS (Tire Pressure Monitoring System) SENSOR TRAINING PROCEDURE
G1 RETRIEVE THE RECORDED DTCs FROM THE SELF-TEST
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: VSM (Vehicle Security Module) Self-Test.
Are there any TPM (Tire Pressure Monitor) /VSM (Vehicle Security Module) DTCs present?
Yes
If DTCs B1359 or B1363 are present, diagnose them first. GO to Pinpoint Test F. Pinpoint Test F: DTCs B1359 and B1363
For all other TPM (Tire Pressure Monitor) /VSM (Vehicle Security Module) DTCs, GO to the TPM (Tire Pressure Monitor) /VSM (Vehicle Security Module) DTC Chart. Tire Monitoring System
No
GO to G2.
G2 CHECK THE TPMS (Tire Pressure Monitoring System) BRAKE ON/OFF (BOO_INPUT) PID
- Enter the following diagnostic mode on the scan tool: VSM (Vehicle Security Module) DataLogger.
- Monitor the BOO_INPUT PID.
- Press and release the brake pedal while monitoring the PID.
Do the brake pedal PID values match the brake pedal positions?
Yes
GO to G3.
No
REFER to Lighting and Horns to continue diagnosis of the stoplamps.
G3 CHECK THE TPMS (Tire Pressure Monitoring System) VEHICLE SPEED SENSOR (VSS) PID
- Monitor the VSS PID.
Is the vehicle speed less than 5 km/h (3 mph)?
Yes
GO to G4.
No
REFER to Instrument Panel, Gauges and Warning Indicators to continue diagnosis of the vehicle speed. If DTC U0155 is present, diagnose it first, REFER to the TPM (Tire Pressure Monitor) /VSM (Vehicle Security Module) DTC Chart. Tire Monitoring System
G4 CHECK FOR CORRECT TPMS (Tire Pressure Monitoring System) OPERATION
- Disconnect all the TPM (Tire Pressure Monitor) /VSM (Vehicle Security Module) electrical connectors.
- Check the connectors for:
- corrosion.
- pushed-out pins.
- spread terminals.
- Connect all the TPM (Tire Pressure Monitor) /VSM (Vehicle Security Module) connectors and make sure they seat correctly.
- Attempt to train the TPMS (Tire Pressure Monitoring System) sensors again. Refer to Tire Pressure Monitoring System (TPMS) Sensor Training .
Is the concern still present?
Yes
The TPMS (Tire Pressure Monitoring System) sensors may not be present. DISMOUNT the tire. REFER to Wheel and Tire . VERIFY the sensors are present and mounted to the wheels. If missing, INSTALL new TPMS (Tire Pressure Monitoring System) sensors.
If the TPMS (Tire Pressure Monitoring System) sensors are present, INSTALL a new TPM (Tire Pressure Monitor) /VSM (Vehicle Security Module). REFER to Tire Pressure Monitor (TPM) Module . TEST the system for normal operation.
No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test.
