CORRECTIVE ACTION
Error Code 325 - Right-Front Wheel Valve
Solenoid, Broken Circuit Failure
1. Check right-front steering
solenoid and wire, located at
steering control valve, for
damage.
Replace solenoid with wire lead
if damaged (WP 0169 00).
2. Check for continuity between
the following connectors and

a. If continuity between pins,
repair or replace connectors
(WP 0111 00).
b. If
continuity
(short)
to
chassis, repair or replace
connectors (WP 0111 00).
c. If continuity is present,
