INSPECTION OF ECM / PCM, IMMOBILIZER
CONTROL MODULE AND ITS CIRCUIT
ECM / PCM, Immobilizer Control Module and its circuit can be
checked at ECM / PCM wiring couplers and Immobilizer Control
Module wiring coupler by measuring voltage and resistance. De-
scribed here is only inspection of Immobilizer Control Module. For
inspection of ECM / PCM, refer to ªSECTION 6E1 or 6E2º.
CAUTION:
Immobilizer Control Module cannot be checked by itself. It
is strictly prohibited to connect voltmeter or ohmmeter to
Immobilizer Control Module with coupler disconnected
from it.
Voltage Check
1) Remove Immobilizer Control Module from body with ignition
switch OFF, referring to p. 8G-24.
2) Connect Immobilizer Control Module coupler to Immobilizer
Control Module.
3) Check voltage at each terminal of coupler connected.
NOTE:
As each terminal voltage is affected by the battery voltage,
confirm that it is 11 V or more when ignition switch is ON.

switch ON before connecting positive probe of voltmeter to A1 or A2 terminal. If it is not turned ON first,
DTC13 (Diagnostic Trouble Code 13) may be indicated.

WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System
Service on and around the air bag system components or wiring must be performed only by an autho-
rized SUZUKI dealer. Refer to ªAir Bag System Components and Wiring Location Viewº under ªGener-
al Descriptionº in air bag system section in order to confirm whether you are performing service on
or near the air bag system components or wiring. Please observe all WARNINGS and ªService Precau-
tionsº under ªOn-Vehicle Serviceº in air bag system section before performing service on or around
the air bag system components or wiring. Failure to follow WARNINGS could result in unintentional
activation of the system or could render the system inoperative. Either of these two conditions may
result in severe injury.
Technical service work must be started at least 90 seconds after the ignition switch is turned to the
ªLOCKº position and the negative cable is disconnected from the battery. Otherwise, the system may
be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
When body servicing, if shock may be applied to air bag system component parts, remove those parts
beforehand. (Refer to Section 10B.)
NOTE:
Fasteners are important attaching parts in that they could affect the performance of vital components and
systems, and / or could result in major repair expense. They must be replaced with one of the same part
number of with an equivalent part if replacement becomes necessary.
Do not use a replacement part of lesser quality or substitute a design. Torque values must be used as spe-
cified during reassembly to assure proper retention of these parts.

CAUTION:
When fasteners are removed, always reinstall them at the same location from which they were re-
moved. If a fastener needs to be replaced, use the correct part number fastener for that application. If
the correct part number fastener is not available, a fastener of equal size and strength (or stronger) may
be used. Fasteners that are not reused, and those requiring thread-locking compound, will be called
out. The correct torque value must be used when installing fasteners that require it. If the above proce-
dures are not followed, parts or system damage could result.
