Interlock Control Unit Input Test
SRS components are located in this area. Review the SRS component locations, precautions, and procedures in the SRS
section (24) before performing repairs or service.
'1. Remove the instrument panel lower cover (see section 20).
2. Disconnect the 8P connector from the interlock control unit.
3. Inspect the connector and connector terminals to be sure they are all making good contact.
. lf the terminals are bent, loose, or corroded, repair them as necessary, and recheck the system
. lf the terminals look OK, make the following input tests at the connector.
- lf a test indicates a problem, find and correct the cause, then recheck the system
- lf all the input tests prove OK, substitute a known-good control unit, and recheck the system. lf the check is OK,
the control unit must be faulty; replace it.
NOTE: lf the shift lock solenoid clicks when the ign ition switch is tu rned ON (ll) while pressing the brake pedal withthe
shift lever in E position, the shift lock system is OK. lf the shift lever cannot be shifted from E position. test the A/T
gear position switch.

2. Shift to N position, then remove the lock pin from
the cable adjuster.
3. Separate the shift cable from the cable adjuster, Do
not bend the shift cable excessively.

with the hole in the adjusting rod. There are two
holes in the cable adjuster. They are positioned 90"

lf not perfectly aligned, loosen the locknut on the
shitt cable. and adjust as required.
Tighten the locknut.
Install the lock pin on the adjuster. lf you feel the
lock pin binding as you reinstall it, the cable is still
out of adjustment and must be readjusted.
Make sure the lock pin is seated securely in the
adjuster. Replace the lock pin if it does not snap
over the cable adjuster securely.
Move the shift lever to each gear, and verify that the
A/T gear position indicator follows the A"/T gear
position switch.
Start the engine, and check the shift lever in all
gears. lf any gear does not work properly, refer to
troubleshooting on page 14-'153 thru 14-156.
Insert the ignition key into the key cylinder on the
upper column cover, and verify that the shift lock

Description
Hydraulic Flow
Forward Start and Acceleration l4WD)During a forward start and forward acceleration, the dual pump system can engage four wheel drive.lf the front wheels spin faster than the rear wheels, the front oil pump spins faster than the rear oil pump. The front pump
draws fluid through check valve B and discharges it. Some of the discharged fluid is drawn in the by the rear oil pump.The remaining fluid will pass through check valve E into the clutch piston. There, hydraulic pressure is regulated by twoorifices.
The regulated hydraulic pressure at the clutch piston pushes the plates and discs of the clutch together to form a connec-tion. The engaged clutch then passes driving force from the transfer assembly to the rear wheels, producing 4WD.
oRrFtcEsFRONT OIL PUMPREAR OIL PUMP
Forward Driving at Constant Speed lzWD)When driving forward at a constant speed (cruising), the dual pump system functions in two wheel drive mode.The rotation speed of the front and rear wheels is the same, so the speed of the front and rear pumps is also the same.Fluid discharged by the front oil pump is drawn in by the rear oil pump and is circulated through the system. Becausethere is no pressure built up at the clutch piston, the clutch does not engage, and the vehicle remains in 2WD (front wheeldrive).
FRONT OIL PUMP

Forward Deceleration l2WDl
During forward deceleration, the dual pump system functions in two wheel drive mode.
Because of braking characteristics, the speed of the rear wheels may exceed the speed ol the front wheels during deceler-
ation. lf so, the rear oil pump spins faster than the front oil pump.
Fluid discharged by the rear oil pump is simply drawn in again by the rear pump and recirculated. Because there is no
pressure built up at the clutch piston. the clutch piston does not engage, and the vehicle remains in 2WD (front wheel
drive).
Reverse Start and Acceleration (4WD)
During reverse start and reverse acceleration, the dual pump system can engage four wheel drive.
lf the front wheels spin faster than the rear wheels, the front oil pump spins faster than the rear oil pump. The front oil
pump draws in fluid through check valve A and discharges it. {Note that in reverse, the direction of the pumps is the oppo-
site of that during forward driving.)
Some of the fluid that is discharged by the front oil pump is drawn in by the rear oil pump. The remaining fluid passes
through check valve F into the cylinder of the clutch piston, where it is regulated by two orifices.
The regulated hydraulic pressure at the clutch piston may force the plates and discs of the clutch together to form a con-
nectlon. The engaged clutch passes driving force from the transfer assembly to the rear wheels, producing 4WD.
