Code B1173 Description
The B1173 diagnostic trouble code indicates that the Gauge Control Module has lost communication with the Tire Pressure Monitoring System (TPMS) Control Unit in the vehicle. The TPMS is a crucial system that monitors the air pressure in the tires and alerts the driver if there is a significant loss of pressure. When the Gauge Control Module is unable to communicate with the TPMS Control Unit, it can lead to inaccurate tire pressure readings being displayed on the dashboard or a complete loss of TPMS functionality.
Common Causes of B1173
- Faulty Gauge Control Module
- Faulty TPMS Control Unit
- Wiring or connection issues between the Gauge Control Module and TPMS Control Unit
- Low battery voltage affecting communication between modules
- Software or programming issues within the vehicle's electronic control units
Symptoms of B1173
- TPMS warning light illuminated on the dashboard
- Inaccurate tire pressure readings displayed on the instrument cluster
- Loss of communication with the TPMS sensors
- Erratic behavior of the TPMS system
How to Fix B1173
- Begin by performing a thorough inspection of the TPMS system, including checking for any loose or damaged wiring connections.
- Use a diagnostic scan tool to retrieve the specific fault codes and identify the exact cause of the communication error.
- If necessary, replace the faulty Gauge Control Module or TPMS Control Unit with a new unit to restore proper communication.
- Clear the fault codes from the vehicle's memory and perform a system reset to ensure that the TPMS is functioning correctly.
- Conduct a road test to verify that the TPMS warning light is no longer illuminated and that accurate tire pressure readings are being displayed.
Cost to Fix B1173
The cost of repairing a communication error between the Gauge Control Module and TPMS Control Unit can vary depending on the specific cause of the issue and the cost of replacement parts.
