Internal failure of the TPMS module itself (most common); Low or unstable battery voltage to the module, causing self-test failure; Corroded or loose ground connection at the module mounting point; Water intrusion or physical damage to the module housing; Software corruption in the module requiring reflash or replacement; Faulty CAN bus communication wiring between the module and other systems

C0960Tire Pressure Monitoring Module Internal Fault

Q: What does code C0960 mean?

Tire Pressure Monitoring Module Internal Fault. C0960 indicates that the tire pressure monitoring system (TPMS) module has detected an internal fault within its own circuitry or software, not a problem with a tire sensor or wiring. The module's self-test has failed, so it can no longer reliably monitor tire pressures or trigger warnings.

Symptoms you may notice

TPMS warning light flashes for about a minute then stays on continuously
Often no symptoms besides the warning light, with no drivability issues
Tire pressure display shows dashes or blank readings on vehicles with a screen
Other driver-assist features that share the module may be disabled
Intermittent warning light that comes and goes with temperature or vibration
No response from the TPMS module during a scan tool communication test

Common causes, most likely first

Internal failure of the TPMS module itself (most common)
Low or unstable battery voltage to the module, causing self-test failure
Corroded or loose ground connection at the module mounting point
Water intrusion or physical damage to the module housing
Software corruption in the module requiring reflash or replacement
Faulty CAN bus communication wiring between the module and other systems

How to diagnose and fix it

Verify battery voltage and charging system output; a weak battery can set this code
Inspect the TPMS module connector and ground for corrosion, tightness, and water damage
Clear the code and perform a module self-test with a scan tool to see if it returns immediately
Check for technical service bulletins (TSBs) for module software updates before replacing parts
If the code persists, replace the TPMS module and perform initialization or programming as required
After replacement, verify communication with the module and confirm the warning light operates correctly

What most technicians overlook with C0960

A weak or failing battery is a frequent cause of this code because the TPMS module's self-test is sensitive to voltage drops during cranking.
This code does not mean a tire sensor is bad; replacing wheel sensors will not fix an internal module fault.
Some vehicles require the new module to be configured or flashed with the correct tire size and placard information before it will work.
Intermittent C0960 can be caused by a poor ground that only acts up when the vehicle is hot or vibrating, so wiggle-test the harness.
A scan tool that can communicate with the TPMS module is essential; generic code readers often cannot retrieve or clear this code.

Can I keep driving with C0960?

You can usually drive with this code because it does not affect braking or steering, but the TPMS will not warn you of low tire pressure. Check tire pressures manually with a gauge regularly and avoid long trips until the fault is repaired.
