If the vehicle is equipped with air bag system, be sure to
enable air bag system after TCM and ECM are back in
place. Refer to “ENABLING AIR BAG SYSTEM” in Section
10B. CAUTION:
TCM and ECM consist of highly precise parts, so when
handling it (or them), be careful not to expose to exces-
sive shock.
NOTE:
When replacing TCM with used one, all learned contents
which are stored in TCM memory should be erased refer-
ring to “LEARNING CONTROL INITIALIZATION” in this
section.

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.
