3B1-26 ELECTRICAL POWER STEERING (P/S) SYSTEM
INSPECTION OF P/S CONTROL MODULE
AND ITS CIRCUITS
P/S control module (1) and its circuits can be checked at P/S con-
trol module wiring couplers (2) by measuring voltage and resis-
tance.
Voltage Check
1) Remove steering column lower cover with ignition switch
OFF position.
2) Check voltage at each terminal with connectors (2) con-
nected P/S control module. CAUTION:
P/S control module cannot be checked by itself. It is
strictly prohibited to connect voltmeter or ohmmeter to
P/S control module with connector disconnected from it.
NOTE:
As each terminal voltage is affected by the battery volt-
age, confirm that it is 11V or more when ignition switch is
ON.

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
authorized SUZUKI dealer. Please observe all WARNINGS and “Service Precautions” under “On-
Vehicle Service” in air bag system section before performing service on or around the air bag sys-
tem 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.
The procedures in this section must be followed in the order listed to temporarily disable the air
bag system and prevent false diagnostic codes from setting. Failure to follow procedures could
result in possible air bag system activation, personal injury or otherwise unneeded air bag system
repairs.
CAUTION:
When fasteners are removed, always reinstall them at the same location from which they were
removed. 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
procedures are not followed, parts or system damage could result.

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
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” 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
“LOCK” 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).
NOTE:
All brake fasteners are important attaching parts in that they could affect the performance of vital
parts and systems, and/or could result in major repair expense. They must be replaced with one of
same part number or with an equivalent part if replacement becomes necessary. Do not use a replace-
ment part of lesser quality or substitute design. Torque values must be used as specified during reas-
sembly to assure proper retention of all parts. There is to be no welding as it may result in extensive
damage and weakening of the metal.

6-36 ENGINE GENERAL INFORMATION AND DIAGNOSIS
INSPECTION OF ECM AND ITS CIRCUITS
ECM and its circuits can be checked at ECM wiring couplers by
measuring voltage and resistance.
VOLTAGE CHECK
1) Remove ECM (1) from vehicle body referring to Section 6E.
2) Check voltage at each terminal of couplers (2) connected.CAUTION:
ECM cannot be checked by itself. It is strictly prohibited
to connect voltmeter or ohmmeter to ECM with coupler
disconnected from it.
NOTE:
As each terminal voltage is affected by the battery volt-
age, confirm that it is 11 V or more when ignition switch
is ON.

TABLE A-1 MALFUNCTION INDICATOR LAMP CIRCUIT CHECK - LAMP DOES
NOT COME “ON” AT IGNITION SWITCH ON (BUT ENGINE AT STOP)
WIRING DIAGRAM
CIRCUIT DESCRIPTION
When the ignition switch is turned ON, ECM causes the main relay to turn ON (close the contact point). Then,
ECM being supplied with the main power, turns ON the malfunction indicator lamp (MIL). When the engine
starts to run and no malfunction is detected in the system, MIL goes OFF but if a malfunction was or is detected,
MIL remains ON even when the engine is running.
