Diagnostic Routine B

Diagnostic Overview

B124D:02

Normal Operation and Fault Conditions

REFER to Tire Pressure Monitoring System (TPMS) Function .

Visual Inspection and Diagnostic Pre-checks

- Inspect for customer electronic devices, such as cell phone chargers or GPS (Global Positioning System) units.

- Inspect for Non-OEM wheels or run-flat tires.

- Verify that the horn operates.

DTC Fault Trigger Conditions







Special Tool(s)






Pinpoint Test

1. CHECK THE SENSOR IDENTIFIERS AND SYSTEM STATUS PIDs (Parameter Identifications)

1. Ignition ON.

2. Using a scan tool, view and record the following BCM (Body Control Module) PIDs (Parameter Identifications):

- Left Front Tire Transmitter Identifier (TPM_S_ID_LF)
- Right Front Tire Transmitter Identifier (TPM_S_ID_RF)
- Left Rear Tire Transmitter Identifier (TPM_S_ID_LRO)
- Right Rear Tire Transmitter Identifier (TPM_S_ID_RRO)

3. Monitor the TPMS (Tire Pressure Monitoring System) PID (Parameter Identification) TPMS_STATUS.

Does the TPMS_STATUS PID (Parameter Identification) display SENSOR FAULT?








2. CARRY OUT THE SENSOR TRAINING PROCEDURE

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).

Did all of the tire pressure sensors transmit correctly and did the horn sound when each TPMS (Tire Pressure Monitoring System) sensor is trained?
