What it means
A control module has detected that the software in the tire pressure monitor module is incompatible with its own software or configuration. Tire-pressure monitoring may be affected; the specific effects depend on the vehicle.
How it works
The tire pressure monitor module receives or processes tire-pressure sensor information and reports it to the vehicle. This code sets when another module finds the monitor module’s software or configuration incompatible with its own, so pressure warnings or monitoring may be unavailable or unreliable.
Common causes
Most likely first.
- Incorrect or incompatible tire pressure monitor module software
- Module replacement without required programming or configuration
- Incorrect module part number
Symptoms
- Multiple warning lights may illuminate
- Affected modules may go into limp mode or shut down
- Specific functions inoperative depending on module
- Diagnostic tools may show communication faults
How to diagnose it
- Check the tires with a pressure gauge and compare them with the vehicle’s placard, since the warning system may not be reliable while this fault is present.
- Scan the tire-pressure monitor and other modules, saving freeze-frame data and related communication or configuration codes.
- Check whether the fault began after tire-pressure module replacement, sensor service, or programming work.
- Read the monitor module’s part number and software identity, then compare them with vehicle-specific service information.
- Inspect accessible module connectors and wiring, then verify module configuration and compatibility using the manufacturer’s procedure.
Common fixes
- Correct any tire pressures found low during manual checks.
- Repair a loose or corroded tire-pressure monitor module connection.
- Complete the required module configuration or sensor registration.
- Program compatible software or replace an incorrect-part-number module with a compatible programmed unit.
Can I keep driving?
You can generally drive if the tires are sound and their pressures are checked manually, but do not rely on the tire-pressure warning system to alert you. Check pressures regularly and stop if a tire appears damaged, loses pressure, or affects handling.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
