TROUBLESHOOTING HINTS

Try the following checks before doing the System Check.

1. Check the In-Line Fuse.

2. Check the PWR ACC Circuit Breaker.

3. If the Lumbar Pump/Motor runs, but both driver's and passenger's Lumbar and Bolster Supports do not operate, check the continuity to ground of BLK/WHT (769) wire (see schematic).

4. Check the hose between the Valve Assemblies and the Pump/Motor for leaks or cracks.

5. Check that G31O is clean and tight.
