DETECT MALFUNCTIONING ITEM
Check the following.
• Harness for short or open between ignition switch and TCM connector terminal 10, 19
Refer to CVT-296, " Wiring Diagram - CVT - POWER " .
• 10 A fuse (No.49, located in the IPDM E/R). Refer to CVT-296, " Wiring Diagram - CVT - POWER " .
• Ignition switch. Refer to PG-3 .
OK or NG OK >> GO TO 4.
NG >> Repair or replace damaged parts. 4.
CHECK TCM GROUND CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect TCM connector.
3. Check continuity between TCM connector terminals and ground. Refer to CVT-296, " Wiring Diagram - CVT - POWER " .
OK or NG OK >> GO TO 5.
NG >> Repair open circuit or short to ground or short to power
in harness or connectors. 5.
DETECT MALFUNCTIONING ITEM
Check the following.
• Harness and fuse for short or open between ignition switch and O/D OFF indicator lamp Refer to PG-3 .
OK or NG OK >> GO TO 6.
NG >> Repair or replace damaged parts. 6.

CVT SHIFT LOCK SYSTEM
Description INFOID:0000000004305812
• The mechanical key interlock mechanism also operates as a shift lock: With the ignition switch turned to ON, selector lever cannot be shifted from “P” position to any other position
unless brake pedal is depressed.
With the key removed, selector lever cannot be shifted from “P” position to any other position.
The key cannot be removed unless selector lever is placed in “P” position.
• The shift lock and key interlock mechanisms are controlled by the ON-OFF operation of the shift lock sole-
noid and by the operation of the rotator and sli der located inside key cylinder, respectively.
