Service Precaution
WARNING: THIS VEHICLE HAS A SUPPLEMENTAL
RESTRAINT SYSTEM (SRS). REFER TO THE SRS
COMPONENT AND WIRING LOCATION VIEW IN
ORDER TO DETERMINE WHETHER YOU ARE
PERFORMING SERVICE ON OR NEAR THE SRS
COMPONENTS OR THE SRS WIRING. WHEN YOU
ARE PERFORMING SERVICE ON OR NEAR THE SRS
COMPONENTS OR THE SRS WIRING, REFER TO
THE SRS SERVICE INFORMATION. FAILURE TO
FOLLOW WARNINGS COULD RESULT IN POSSIBLE
AIR BAG DEPLOYMENT, PERSONAL INJURY, OR
OTHERWISE UNNEEDED SRS SYSTEM REPAIRS.
CAUTION: Always use the correct fastener in the
proper location. When you replace a fastener, use
ONLY the exact part number for that application.ISUZU will call out those fasteners that require a
replacement after removal. ISUZU will also call out
the fasteners that require thread lockers or thread
sealant. UNLESS OTHERWISE SPECIFIED, do not
use supplemental coatings (Paints, greases, or other
corrosion inhibitors) on threaded fasteners or
fasteners joint interfaces. Generally, such coatings
adversely affect the fastener torque and the joint
clamping force, and may damage the fasteners.
When you install fasteners, use the correct
tightening sequence and specifications. Following
these instructions can help you avoid damage to
parts and systems.

MID Control Unit
Removal
1. Disconnect the battery ground cable.
2. Remove the MID control unit (3).

Refer to
MID (1) in this section.

Remove the control unit (3) from the bracket (2).
CAUTION: When the battery is disconnected, the
MID control unit directional data is lost (the control
unit returns to its start-up condition). When the
battery is reconnected, the display will be erroneous
until the control unit receives a clear GPS satellite
signal and resets its directional data.
After reconnecting the battery, wait until the satellite
mark indicator turns on. Select an area where there
are no high buildings or other obstacles to electro-
magnetic waves. Drive the vehicle in a straight line at
a speed exceeding 32 km/h (20 mph) for at least 20 se-
conds.
