Diagnostic Routine I

Diagnostic Routine I

Diagnostic Overview

One or More Tire Pressure Monitoring System Sensors Do Not Train and No DTCs are Present

Normal Operation and Fault Conditions

REFER to Tire Pressure Monitoring System (TPMS) Function .

If the vehicle has been stationary for more than 30 minutes, the TPMS (Tire Pressure Monitoring System) 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 TPM (Tire Pressure Monitor) module. REFER to Tire Pressure Monitoring System (TPMS) Sensor Activation Tire Pressure Monitoring System (TPMS) Sensor Activation.

Visual Inspection and Diagnostic Pre-checks

- Inspect for customer electronic devices, such as a cell phone charger or GPS (Global Positioning System) unit.

- Inspect for non- OEM (Original Equipment Manufacturer) wheel or run-flat tires.

Special Tool(s)






Pinpoint Test

1. ATTEMPT TO TRAIN THE TPMS (Tire Pressure Monitoring System) SENSORS

NOTE: The BCM (Body Control Module) has a 2-minute time limit between sensor responses. If the BCM (Body Control Module) does not recognize any of the 4 TPMS (Tire Pressure Monitoring System) sensors during this time limit, the horn sounds twice, the message center displays TIRE NOT TRAINED REPEAT, and the entire procedure must be repeated.

1. TRAIN all 4 TPMS (Tire Pressure Monitoring System) sensors. REFER to Tire Pressure Monitoring System (TPMS) Sensor Training - Intelligent Access (IA) Tire Pressure Monitoring System (TPMS) Sensor Training - Intelligent Access (IA) or REFER to Tire Pressure Monitoring System (TPMS) Sensor Training - Integrated Keyhead Transmitter (IKT) Tire Pressure Monitoring System (TPMS) Sensor Training - Integrated Keyhead Transmitter (IKT).

Do all of the TPMS (Tire Pressure Monitoring System) sensors train?








2. CHECK FOR RADIO FREQUENCY INTERFERENCE

1. Ignition ON.

2. Move the vehicle to rotate the wheels at least one-fourth turn.

3. TRAIN all 4 TPMS (Tire Pressure Monitoring System) sensors. REFER to Tire Pressure Monitoring System (TPMS) Sensor Training - Intelligent Access (IA) Tire Pressure Monitoring System (TPMS) Sensor Training - Intelligent Access (IA) or REFER to Tire Pressure Monitoring System (TPMS) Sensor Training - Integrated Keyhead Transmitter (IKT) Tire Pressure Monitoring System (TPMS) Sensor Training - Integrated Keyhead Transmitter (IKT).

Did the TPMS (Tire Pressure Monitoring System) sensor(s) train?
