ELECTRICAL TROUBLESHOOTING MANUAL
CIRCUIT OPERATION
Selector Interlock
When the gear selector is in the park position, the
solenoid inside the Transmission Range Selector
Switch (Z110) is de±energized and prevents the
selector from being moved into another gear. To
free the selector, the Ignition Switch (X134) must
be in position II and the brake pedal must be
depressed. When this occurs, voltage from Fuse
F1 is applied to the Transmission Range Selector
through the closed Stop Lamp Switch (X168). The
solenoid inside the Transmission Range Selector
Switch is grounded at E200 through the selector
switch, the KS wire and the B wire. The solenoid
then energizes, freeing the selector.
Ignition Key Interlock
On vehicles equipped with the interlock safety
feature the vehicle must be in park and the transfer
case in high or low gear before the key can be
removed from the ignition. If the gear selector or
transfer gear are out of gear, the key must be
cycled before removal.
If the vehicle is not in park, voltage from Fuse F12
is applied to the Key Barrel Switch (X230) through
the closed contacts of the Transmission Range
Selector Switch (Z110). When the Ignition Switch is
placed in the 0 position, the Key Barrel Switch
(X230) closes to energize the solenoid and prevent
key removal.
If the key is in the ignition and the transfer box is in
the neutral position, Interlock Relay 1 (K153) is
de±energized since the relay coil is not grounded
by the Transfer Box Position Switch (X175). When
the relay is de±energized, voltage is applied to the
Key Barrel Switch (X230) through the relays switch
contacts and the Key±In Switch (X229) causing the
solenoid to energize and prevent key removal.
If the transfer box is in the ªHº or ªLº position, the
Interlock Relay 1 (K153) is energized, since the
relay coil is grounded by the Transfer Box Position
Switch (X175). When the relay is energized,
voltage to the Key Barrel Switch (X230) is
interrupted. The Ignition Key Lock Solenoid (K191)
is then disabled, allowing removal of the key.
If the Transfer Box is switched to ªNº position, the
Transfer Box Warning Relay (K186) is
de±energized, providing ground to the MultifunctionUnit (Z148). An internal sounder provides a
warning chime to the driver.
Transfer Box Interlock
The Transfer Box Interlock Safety feature is
designed to prevent the transfer case shifter from
being shifted out of ªHº or ªLº unless the vehicles
gear selector is in the neutral position.
When the gear selector is placed in the neutral
position, voltage is applied to the Interlock Relay
2s coil through the Transmission Range Selector
Switch (Z110). The relays coil is grounded through
the Park/Neutral Position Switch (X167).
Interlock Relay 2 now energizes and applies
voltage from Fuse F13 to the Transfer Box
Solenoid (K154). When the Transfer Box Solenoid
(K154) is energized the transfer box shifter can be
operated.
