Overdrive Control Switch
OVERDRIVE CONTROL SWITCHDescription
^ Overdrive control switch is installed to the selector lever.
^ O/D OFF indicator turns ON, and overdrive driving activates when pressing the overdrive control switch while driving in "D" position. O/D OFF indicator turns OFF, and "D" position driving starts when pressing the overdrive control switch while driving in the overdrive-off mode. Shifting the selector lever in any position other than "D" releases the overdrive-off mode.

Diagnosis Procedure
1. CHECK CAN COMMUNICATION LINE
Perform the self-diagnosis check. Refer to CVT-47, "CONSULT-III Function (TRANSMISSION)". Consult-III Function (Transmission)
Is any malfunction of the "U1000 CAN COMM CIRCUIT" indicated in the results?
YES >> Check CAN communication line. Refer to CVT-56. U1000
NO >> GO TO 2.
2. CHECK OVERDRIVE CONTROL SWITCH SIGNAL
WITH CONSULT-III
1. Turn ignition switch ON.
2. Select "ECU INPUT SIGNALS" in "DATA MONITOR" mode for "TRANSMISSION" with CONSULT-III.
3. Read out ON/OFF switching action of the "SPORT MODE SW".
OK or NG
OK >> INSPECTION END
NG >> GO TO 3.
3. CHECK OVERDRIVE CONTROL SWITCH
Check overdrive control switch. Refer to "Component Inspection"
OK or NG
OK >> GO TO 4.
NG >> Repair or replace damaged parts.
4. CHECK SELF-DIAGNOSTIC RESULTS (COMBINATION METER)
Perform self-diagnosis check. Refer to DI-11, "Self-Diagnosis Mode of Combination Meter". Self-Diagnosis Mode Function
Is any malfunction detected by self-diagnostic?
YES >> Check the malfunctioning system.
NO >> - 1 >> With intelligent key: GO TO 5.
NO >> - 2 >> Without intelligent key: GO TO 6.
5. CHECK OVERDRIVE CONTROL SWITCH CIRCUIT
