TEST OR INSPECTION
Remove rings, wristwatches, neck chains, and any other jewelry before working
around vehicle. Jewelry can catch on equipment and cause serious injury. Jewelry
and tools may short across electrical circuits and cause damage to equipment, or
severe burns or electrical shock to personnel.
Turn battery disconnect switch to OFF position (WP 0007). With a test lead set, check
for continuity across wire 2200 (black) from valve control wire harness foam flush
shutoff control valve connector, terminal 2 to a known good ground.
If there is continuity, replace shutoff control valve manifold (WP 0427).
