AUTOMATIC TRANSMISSION (4 A/T) 7B-53
INSPECTION OF TCM AND ITS CIRCUITS
TCM and its circuits can be checked at TCM wiring couplers by
measuring voltage and resistance.
INSPECTION
1) Remove TCM from vehicle referring to “TRANSMISSION
CONTROL MODULE” in this section.
2) Connect TCM couplers to TCM.
3) Check voltage at each terminal of couplers connected.CAUTION:
TCM cannot be checked by itself, it is strictly prohibited
to connect voltmeter or ohmmeter to TCM 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.

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. 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).
