What to do if CMS DTCs become active during service on WABCO Automobile Accessories?
If CMS DTCs become active when you are servicing other electrical components, complete the repairs on those other vehicle systems first. Then, cycle the ignition OFF for at least two minutes before turning it back ON.
Why is service alignment important for WABCO Automobile Accessories?
Service alignment is important because adjustments, repairs, replacements, or maintenance affecting tires, chassis, or front body components require a service alignment to be performed afterward. Failing to do so may result in driveability concerns.
What to do if WABCO Security Sensors system is not operating correctly?
If the WABCO Security Sensors system isn't working right and shows a fault code, first, use the UP and DOWN keys on the OnGuard display to check each fault code and write them down for later. Remember, the OnGuard system, including ACC, CWS, CMS, and cruise control, will be disabled when active codes appear. If you find a fault code that's not in the Fault Code Tables, call WABCO North America Customer Care at 855-228-3203 for help. Also, keep in mind that OnGuard fault codes can pop up during service on other electrical parts. After you're done fixing those parts, turn the ignition OFF for a minute, then back ON, and let the engine idle for a minute. This often clears the OnGuard fault code.
How to clear OnGuard fault codes on WABCO Security Sensors?
