If your Honda vehicle is displaying the B1173 code, it is important to take the time to diagnose and repair the issue. The B1173 code indicates poor communication between the Gauge Control Module and the TPMS Control Unit, which can cause your Honda to suffer various problems. There are a variety of causes for the B1173 code, from loose connections to faulty modules, and each cause requires a different solution. Taking the time to diagnose and repair the issue properly can help ensure that your Honda runs safely and efficiently.
Check for TPMS DTCs
The first step in diagnosing the B1173 code is to check for any TPMS Diagnostic Trouble Codes (DTCs). It is important to check for any DTCs before proceeding with any repairs, as this can help to narrow down the possible causes of the B1173 code. To check for any DTCs, a diagnostic scan tool should be used to run a series of tests.

Check Connections
If no DTCs are found, the next step is to check for any loose or poor connections between the Gauge Control Module and the TPMS Control Unit. It is important to check these connections as they can easily become loose or disconnected, causing the B1173 code to appear. If any connections are found to be flexible or confusing, they should be repaired or replaced.
Check for Open or Short
If the connections are good, the next step is to check for an open or short between the Gauge Control Module and the TPMS Control Unit. To do this, a voltmeter should measure the voltage between the two modules. If the voltmeter readings are not within the expected range, then there is an open or short, and the modules should be replaced.
Replace Faulty Modules
If the connections and voltmeter readings are good, then the cause of the B1173 code is likely due to a faulty Gauge Control Module or TPMS Control Unit. In this case, the defective module should be replaced to resolve the issue.
