Tire Pressure Monitoring System: 8004
8004 - TIRE PRESSURE SENSOR/TRANSMITTER FAILURE
When Monitored and Set Condition
- When Monitored: With the ignition ON, the Tire Pressure Monitor (TPM) module monitors the signal transmitted from each of the Tire Pressure Sensors.
- Set Condition: If the Tire Pressure Monitor (TPM) module detects a loss of a Tire Pressure Sensor signal from one or more of the Tire Pressure Sensors, this DTC will be set.
Diagnostic Test
1. READING TPM DIAGNOSTIC TROUBLE CODES
NOTE: DTC 8004 will always be set in conjunction with one or more of the Tire Pressure Sensor/Transmitter Failure DTCs. Either 8017 (LF Tire), 8018 (RF Tire), 8019 (RR Tire), or 8020 (RF Tire) will be set along with the 8004 code.
NOTE: The Tire Pressure Sensor/Transmitters can set this DTC if the vehicle is sitting still for a prolonged period of time and the key is ON. The Tire Pressure Sensor/Transmitter must be tested properly prior to replacement.
Turn the ignition on.
With the DRB III(R), read and record the TPM DTCs.
Refer to the appropriate Tire Pressure Sensor/Transmitter Failure DTC for proper diagnostic and repair procedures.
