Control Module: Testing and Inspection
TCM Initialization and Learning ControlIn this operation, perform initialization procedure before performing learning control procedure.
CAUTION:
^ When replacing TCM and CVT assembly, be sure to perform "TCM Initialization and Learning Control".
^ When replacing TCM and CVT assembly, replace CVT assembly first and then replace TCM. If CVT assembly is replaced before replacing TCM, be sure to perform initialization procedure [B].
^ Neglecting this initialization may result in excessive shift shock.
Initialization Procedure
1) Select initialization procedure from table below.
2) Perform selected initialization procedure as follows.
Initialization procedure [A]:
a) Push engine switch to change ignition mode to "ON" and shift select lever to "P" range.
b) Check that the shift position indicated in information display comes on in approx. 2 sec. after engine switch is pressed to change ignition mode to "ON". If the shift position does not come on, check the following items:
^ Check for open or shorted to ground in wiring harness between TCM and ROM in CVT assembly.
^ Check for proper terminal connection to TCM connector and solenoid connector.
Initialization procedure [B]:
a) Confirm that ignition mode of keyless push start system is "OFF" and connect SUZUKI scan tool to DLC (1).
Special Tool
(A): SUZUKI scan tool (SUZUKI-SDT)
b) Push engine switch to turn "ON" ignition switch.
c) Select "Learning Value Initialization" function under "Utility" mode on SUZUKI scan tool, and follow the instructions displayed on SUZUKI scan tool.
d) Push engine switch to change ignition mode to "OFF" and leave ignition mode in "OFF" for 10 sec.
e) Shift select lever to "P" range.
f) Check that the shift position indicated in information display comes on in approx. 2 sec. after engine switch is pressed to change ignition mode to "ON". If the shift position does not come on, check the following items:
^ Check for open or shorted to ground in wiring harness between TCM and ROM in CVT assembly.
^ Check for proper terminal connection to TCM connector and solenoid connector.
Learning Control Procedure
CAUTION:
To perform the learning function normally, follow instructions below:
^ When operating the select lever, hold it for more than 2 sec. in each position.
^ Do not shift the select lever from "N" position to other positions until specified idle engine speed is obtained.
Cold condition
1) Select "Data List" mode on SUZUKI scan tool.
2) Cool down CVT fluid to ambient temperature.
3) Start engine.
4) Depress brake pedal fully and repeat shift operation from "N" range to "D" range, and from "N" range to "R" range 3 times for each gear shift. If excessive shift shock is observed, repeat this operation 10 times.
5) Depress brake pedal fully at idle speed and hold in "D" range for 20 sec.
6) Drive vehicle so that CVT fluid temperature reaches 40° C (104° F)
7) Drive vehicle at 40 - 50 km/h (25 - 31 mile/h) constantly for 5 sec. in "D" range.
Hot condition
1) Drive vehicle so that CVT fluid temperature reaches 80° C (176° F)
2) Depress brake pedal fully and repeat shift operation from "N" position to "D" position and from "N" position to "R" position 3 times each. If excessive shift shock is observed, repeat this operation 10 times.
3) Depress brake pedal fully at idle speed and hold in "D" position for 20 sec.
4) Drive vehicle at 40 - 50 km/h (25 - 31 mile/h) constantly for 5 sec. in "D" position.
