Checking cable and component

Check connector D for the rear electronic module (REM) and the connector for the inclination sensor module (ISM). Check for contact resistance and oxidation.

Check the power cable between rear electronic module (REM) connector terminal #31 (#D31) and inclination sensor module (ISM) connector terminal #1. Check for an open-circuit.

Check the communication cable between rear electronic module (REM) connector terminal #26 (#D26) and inclination sensor module (ISM) connector terminal #2. Check for an open-circuit.

Check the cable between inclination sensor module (ISM) connector terminal #5 and the ground terminal. Check for open-circuit.

Try a new inclination sensor module (ISM) if no fault is found.

Remedy as necessary.
