7D1-46 TRANSFER CONTROL SYSTEM
Diagnosis
Before determining a trouble (Non-trouble mode)
1. When shifting from 2H to 4H:
1-1-1 When the flashing frequency of the 4WD indicator is changed from 2Hz to 4Hz (Shift on the fly) If the load is too large to shift the gears synchronously, the operation is repeated up to 3 times. If the shifting
is not effected after being repeated 3 times, the indicator frequency is changed from 2Hz to 4Hz. At the same
time, the actuator condition is changed to 2H, indicator flashes at 4Hz for 10 seconds, and then goes out.
Cause of excessive synchronous shifting load
• Extremely low temperature (the oil viscosity of the front differential increases requiring a large load for
synchronization).
• High speed (since the difference of relative revolutions of gears to be shifted synchronously is too large,
required work load per unit time becomes larger).
Step 1-1-1:
Stop the vehicle or decrease the speed and operate as required again.
1-1-2 When the flashing frequency of the 4WD indicator is changed from 2Hz to 4Hz (Rigid and free wheel
Hub) / Block out of meshing spline in transfer case.
Step 1-1-2:
Run the vehicle forward and backward several meters and operate as required again.
1-2 When the flashing of 4WD indicator at 2Hz continues more than 11.5 seconds (repetition of 3 times of
above No.1 is counted) (Shift on the fly)
If there is difference of revolutions and phases between the front wheel and the axle, connecting the front
wheel and axle is difficult.
Until shifting in the transfer and connection of the front wheel and axle are completed
∗, the indicator flashes at
a frequency of 2Hz. In the above case, the indicator continues flashing at a frequency of 2Hz until the
connection of the front axle is completed. (If the shifting in the transfer is not completed, the flashing
frequency is changed to 4Hz (above No.1).)
By correcting the difference of relative revolutions and deviation of phases, the shifting can be completed.
Step 1-2:
While the vehicle is running, check it is safe around the vehicle and then accelerate or decelerate the
vehicle while going straight.
When the vehicle is at a stop, run the vehicle forward and backward several meters.

2. When shifting from 4H to 2H
2-1 When 4WD indicator continues flashing at 2Hz
W hen shifting from 4H to 2H, the 4W D indicator continues flashing at 2Hz until separation in the transfer and
the separation of the front wheel axle are completed∗. W hen torsional torque is accumulated in the drive
system, separation in the transfer and separation of the front axle∗ is difficult. In such a case, they can be
separated by removing the torsional torque of the drive system.
Step 2-1:
While the vehicle is running, check it is safe around the vehicle and then accelerate or decelerate the
vehicle while going straight.
When the vehicle is in stop, run the vehicle several meters forward and backward.

∗: Shift on the fly only.

SUPPLEMENTAL RESTRAINT SYSTEM 9A-17
“Continuous Monitoring”
Tests are performed by the SRS control unit on the
SRS every 100 milliseconds while “Ignition 1” voltage
is in the normal operating voltage range at the SRS
control unit.

Formerly “DLC”, a connector which allows
communication with an external computer, such as a
scan tool.
Datum Line
A base line parallel to the plane of the underbody or
frame from which all vertical measurements originate.

SUPPLEMENTAL RESTRAINT SYSTEM 9A-33
Inspections Required After An Accident
CAUTION: Certain SRS components must be
replaced after a frontal crash involving air bag
deployment.
In all types of accidents regardless of “Air Bag”
deployment, visually inspect all of the following
components and replace as required:
– Driver air bag assembly
– Passenger air bag assembly
– Steering wheel
– SRS coil assembly
– Steering column
– Knee bolster and instrument panel mounting attachments
– Driver seat and belt
– Passenger seat and belt
– SRS control unit
The SRS control unit should always be checked
according to “SRS Control Unit Replacement
Guidelines.”
CAUTION: Refer to “SRS control unit Replacement
Guidelines” below for important information on
SRS control unit replacement in both deployment
and non–deployment crashes.
Inspect the SRS coil assembly wiring and the steering
wheel for any sign of scorching, melting, or damage
due to excessive heat. If the coil assembly wire o
r
steering wheel is damaged, replace them. The
steering column and wheel must be dimensionall
y
checked to determine if they are damaged. Refer to
“steering wheel” in this manual.
Never use SRS parts from another vehicle. This does
not include remanufactured parts purchased from an
authorized ISUZU/GM Retailer; they may be used fo
r
SRS repairs.
Do not attempt to repair the SRS control unit, the SRS
harness, the SRS coil assembly, the air bag assembly,
the steering wheel, or the steering column. Service o
f
these items is replacement only. Verify replacement
part numbers.
CAUTION: Proper operation of the SRS control
unit and the supplemental restraint system (SRS)
requires that any repairs to the vehicle structure
return it to its original production configuration.

SRS Connectors
CAUTION: The special yellow color connectors are
used for the supplemental restraint system-air bag
circuit. When removing the cable harness, do not
pull the cables otherwise cable disconnection may
occur. When connecting the SRS connector, insert
the connector completely. Imperfect locking may
cause malfunction of the SRS circuit.
Removal
To remove the connector, hold the cover insulator (1)
and pull it. The cover insulator slides and the lock will
be released. Do not hold the socket insulator (2).
