Pinpoint Test G: One Or More TPMS Sensors Do Not Train And No DTCs Are Present

NOTE: If the vehicle has been stationary for more than 30 minutes, the sensors go into a sleep mode to conserve battery power. It becomes necessary to wake them up so they transmit the latest tire pressure information to the Body Control Module (BCM). For additional information, refer to Tire Pressure Monitoring System (TPMS) Sensor Activation Tire Pressure Monitoring System (TPMS) Sensor Activation.

Normal Operation

The BCM monitors the tire pressure of all 4 road tires. The wheel-mounted tire pressure sensors transmit signals via radio frequency to the Tire Pressure Monitor (TPM) module. The TPM module is a radio receiver that collects the tire pressure data from the tire pressure sensors. The TPMS sensor radio transmissions are sent approximately once every 60 seconds when the vehicle speed exceeds 32 km/h (20 mph). The BCM learns the position on the vehicle of each TPMS sensor through the training process. Refer to Tire Pressure Monitoring System (TPMS) Sensor Training Tire Pressure Monitoring System (TPMS) Sensor Training for the complete sensor training procedure.

This pinpoint test is intended to diagnose the following:

- TPMS sensors
- Radio Frequency Interference (RFI)

PINPOINT TEST G: ONE OR MORE TPMS SENSORS DO NOT TRAIN AND NO DTCs ARE PRESENT

-------------------------------------------------
G1 ATTEMPT TO TRAIN THE TPMS SENSORS

NOTE: Banded TPMS sensors are not compatible with the valve mounted TPMS sensor system.

NOTE: The BCM has a 2-minute time limit between sensor responses. If the BCM does not recognize any 1 of the 4 tire pressure sensors during this time limit, the horn sounds twice, the message center displays TIRE NOT TRAINED REPEAT, and the entire procedure must be repeated.

- Train all 4 TPMS sensors. Refer to Tire Pressure Monitoring System (TPMS) Sensor Training Tire Pressure Monitoring System (TPMS) Sensor Training.
- Do all of the TPMS sensors train?

Yes
The system is operating correctly at this time. The concern may have been caused by RFI.

No
If one or more TPMS sensors trained, GO to G2. If none of the TPMS sensors trained, GO to Pinpoint Test E. Pinpoint Test E: The Body Control Module (BCM) Cannot Enter Sensor Training Mode When Using the Tire Pressure Monitoring System

-------------------------------------------------
G2 CHECK FOR RADIO FREQUENCY INTERFERENCE

- Ignition ON.
- Move the vehicle to rotate the wheels at least one-fourth turn.
- Train all 4 TPMS sensors. Refer to Tire Pressure Monitoring System (TPMS) Sensor Training Tire Pressure Monitoring System (TPMS) Sensor Training.
- Did the TPMS sensor(s) train?

Yes
The system is operating correctly at this time. The concern may have been caused by RFI.

No
ATTEMPT to train the TPMS sensor(s) with the doors open. If the TPMS sensor(s) still do not train INSTALL a new TPMS sensor(s) for the sensor(s) in question. REFER to Tire Pressure Monitoring System (TPMS) Sensor Service and Repair. TEST the system for normal operation.
