OD OFF indicator lamp does not come on for about 2 seconds when turning ignition switch to ON.
DIAGNOSTIC PROCEDURE 1.
CHECK CAN COMMUNICATION LINE
Perform self-diagnosis. Refer to AT-79, " CONSULT-III Function (TRANSMISSION) " .
Is a malfunction in CAN communication indicated in the results? YES >> Check CAN communication line. Refer to
AT-88 .
NO >> GO TO 2. 2.
CHECK TCM POWER SOURCE
1. Turn ignition switch ON. (Do not start engine.)
2. Check voltage between TCM connector terminals and ground.
Refer to AT-169, " Wiring Diagram - AT - MAIN " .
3. Turn ignition switch OFF.
4. Check voltage between TCM connector terminals and ground.
OK or NG OK >> GO TO 4.
NG >> GO TO 3. 3.
DETECT MALFUNCTIONING ITEM
Check the following.
• Harness for short or open between ignition switch and TCM connector terminals 10, 19. Refer to AT-169," Wiring Diagram - AT - MAIN " .
• Harness for short or open between battery and TCM connector terminal 28. Refer to AT-169, " Wiring Dia-
gram - AT - MAIN " .
• 10A fuse (No.13, located in the fuse block) and 10A fuse (No.49, located in the IPDM E/R). Refer to AT-169," Wiring Diagram - AT - MAIN " .
• Ignition switch. Refer to PG-3 .
OK or NG OK >> GO TO 4.
NG >> Repair or replace damaged parts. 4.

REMOVAL AND INSTALLATION
Removal 1. Disconnect the battery negative terminal.
2. Remove engine under cover and fender protector (LH). Refer to EI-24, " Removal and Installation " .
3. Drain the A/T fluid. Refer to AT-17 .
4. Remove oil pan and oil pan gasket.
5. Check for foreign materials in oil pan to help determine cause of malfunction. If the ATF is very dark, smell burned or contains for-
eign particles, friction material (clutches, band) may need
replacement. A tacky film that will not wipe clean indicates var-
nish build up. Varnish can cause valves, servo, and clutches to
stick and can inhibit pump pressure.
• If ATF contains frictional material (clutch, bands, etc.),
replace radiator and flush cooler line using cleaning sol-
vent and compressed air after repair of A/T. Refer to CO-38 .
6. Remove magnets from oil pan. 1. A/T 2. O-ring 3. Return spring
