AV-SCANNER / Service function guides / Steering and suspension
This guide delivers a complete, professional procedure for diagnosing Tire Pressure Monitoring System (TPMS) faults by separating flat sensor batteries from receiver or communication failures. It is written for working mechanics and experienced DIYers who already understand basic electrical testing and want a structured, repeatable diagnostic path. You will learn how to confirm sensor signal output, isolate receiver and antenna faults, and verify repairs with scan-tool data and road tests. By the end, you will be able to diagnose most TPMS complaints without replacing parts on guesswork and document the result for the customer.
Guidance is general and covers many makes. Exact procedures and values vary by model, so confirm them in the factory service information for your vehicle.
