Transmission Mode Switch: Testing and Inspection
Diagnosis Procedure
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 (SMODE) 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.
S-MODE SWITCH
Diagnosis Procedure
1.CHECK DTC WITH "COMBINATION METER"
See: Instrument Panel, Gauges and Warning Indicators/Testing and Inspection/Scan Tool Testing and Procedures/CONSULT-III
Function/CONSULT-III Function (Meter/ M & A)
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
