Transmission Mode Switch: Testing and Inspection

S-MODE SWITCH

Description

When S-MODE switch is pressed (less than 1 second), S-MODE indicator illuminates, combination meter sends S-MODE switch signal to ECM via the CAN communication, and then Synchrorev Match mode (S-MODE) is activated. When S-MODE is pressed and held (1 second or more), S-MODE indicator turns OFF
and S-MODE is cancelled, and then returns to normal M/T.


Component Function Check


1. CHECK S-MODE SWITCH FUNCTION-I

NOTE:
If DTC UXXXX are displayed, first perform the trouble diagnosis for DTC UXXXX.
1.Turn ignition switch ON.
2.Select "M/T SYNCHRO SW" in "DATA MONITOR" mode with CONSULT.
3.Check "M/T SYNCHRO SW" indication under the following conditions.





Is the inspection result normal?
YES- GO TO 2.
NO- Go to .

2. CHECK S-MODE SWITCH FUNCTION-II

Check the S-MODE indicator under the following condition.





Is the inspection result normal?
YES- INSPECTION END
NO- Go to .


Diagnosis Procedure


1. CHECK DTC WITH "COMBINATION METER"

Meter.
Is the inspection result normal?
YES- GO TO 2.
NO- Perform trouble diagnosis relevant to DTC indicated.

2. CHECK S-MODE SWITCH POWER SUPPLY CIRCUIT

1.Turn ignition switch OFF.
2.Disconnect S-MODE switch harness connector.
3.Turn ignition switch ON.
4.Check the voltage between S-MODE switch harness connector and ground.





Is the inspection result normal?
YES- GO TO 4.
NO- GO TO 3.

3. DETECT MALFUNCTIONING PART

Check the following.
- Harness connectors M98, M252
- Fuse block (J/B) connector M1
- 10 A fuse (No. 3)
- Harness for open or short between S-MODE switch and fuse
- Repair open circuit, short to ground or short to power in harness or connectors.

4. CHECK S-MODE SWITCH INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT

1.Turn ignition switch OFF.
2.Disconnect combination meter harness connector.
3.Check the continuity between S-MODE switch harness connector and combination meter harness connector.





4.Also check harness for short to ground and short to power.
Is the inspection result normal?
YES- GO TO 6.
NO- GO TO 5.

5. DETECT MALFUNCTIONING PART

Check the following.
- Harness connectors M98, M252
- Harness for open or short between S-MODE switch and combination meter
- Repair open circuit, short to ground or short to power in harness or connectors.

6. CHECK S-MODE SWITCH

.
Is the inspection result normal?
YES- GO TO 7.
NO- Replace S-MODE switch.

7. CHECK INTERMITTENT INCIDENT

Intermittent Incident Regular Grade.
- INSPECTION END
