7B-70 AUTOMATIC TRANSMISSION (4 A/T)
LEARNING CONTROL INITIALIZATION
When one or more operations such as shown below are per-
formed, all learned contents which are stored in TCM memory
should be erased after the operations.
Replacing transmission with new or used one.
Repairing transmission partially by replacing any brake com-
ponent parts with new and/or used brake disc(s), plate(s)
and/or flange.
Repairing transmission partially by replacing any clutch com-
ponent parts with new and/or used clutch disc(s), plate(s)
and/or flange.
Replacing TCM with used one.
1) Turn ignition switch ON, leaving engine OFF.
2) Using service wire, connect diagnosis switch terminal (2)
with ground terminal (3) of monitor connector No.2 (1).
3) Shift selector lever from “D” range to “2” range 3 times
repeatedly within 10 seconds with diagnosis switch terminal
(2) kept on connecting with ground.
4) Check DTC referring to “DTC CHECK” in this section and
confirm that only DTC No.12 is displayed.
If not, repeat Step 1) to Step 3) and check again.
BRAKE INTERLOCK SYSTEM (IF EQUIPPED)
SHIFT LOCK SOLENOID CONTROL
This system consists of shift lock solenoid control system and
interlock cable control system.
The shift lock solenoid control system is so designed that the
selector lever can not be shifted from “P” range position unless
ignition switch is turned ON and the brake pedal is depressed.
And interlock cable control system is so designed that select lever
cannot be shifted from “P” range position unless ignition switch is
turned to “ACC” or “ON” position. Also, ignition key cannot be
pulled out of key slot unless selector lever is in “P” range. NOTE:
 “O/D OFF” lamp lights during initializing.
 Diagnostic trouble code(s) (DTC(s)) also are erased by
performing this initializing procedure.
 After initializing is achieved, DTC No.12 is stored in
TCM. If initializing is failed, DTC No.52 is stored in
TCM.

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).
