CORRECTIVE ACTION
Error Code 418 - 2WD Steering Selection Switch,
Circuit Failure
1. Check
voltage
at

steering
selection
switch
connector 136 pin 5. Voltage
should be 22-26V.
If voltage is not as specified,
check wire 1529B for damage.
Repair or replace connectors
(WP 0111 00).
2. Check
voltage
at
2WD
steering
selection
switch

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, notify
SRA.
4. Check continuity between
connector X153 pin 13 and
connector X160 pin 13.
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).
