Fault-Tracing Information

Check the cable between Central electronic module (CEM) terminal #H:17 and movement sensor (MMS) or (IMS) terminal #3.

• Connect the breakout box adapter to the central electronic module (CEM).
• Take readings between Central electronic module (CEM) terminal #H:17 (#31) and terminal #A:14 (#14). Also measure between Central electronic module (CEM) terminal #H:17 and movement sensor (MMS) or (IMS) terminal #3. Locate any short-circuits to voltage or ground. There should be no contact with power supply or ground.

If no fault is found on the cable, replace mass movement sensor (MMS) or (IMS).

Remedy as necessary.
