TCM Self-Diagnosis Does Not ActivateINFOID:0000000001696261
SYMPTOM:
OD OFF indicator lamp does not come on in TCM self-diagnostic procedure even if the lamp circuit is
good.
DESCRIPTION
PNP switch
PNP switch assembly includes a transaxle position switch. The
transaxle position switch detects the selector lever position and
sends a signal to the TCM.
Overdrive control switch
Overdrive control switch detects the switch position (ON or OFF)
and sends a signal to the TCM.

ON-VEHICLE MAINTENANCE
A/T FLUID
Checking A/T FluidINFOID:0000000001728293
1. Warm up engine.
2. Check for A/T fluid leakage.
3. Before driving, A/T fluid level can be checked at A/T fluid tem-
peratures of 30 to 50°C (86 to 122°F) using the “COLD” range
on A/T fluid level gauge.
a. Park vehicle on level surface and set parking brake.
b. Start engine and move selector lever through each gear posi-
tion. Leave selector lever in “P” position.
c. Check A/T fluid level with engine idling.
d. Remove A/T fluid level gauge and wipe clean with lint-free cloth.
CAUTION:
When wiping the A/T fluid level gauge, always use lint-free
cloth.
e. Re-insert A/T fluid level gauge into A/T fluid charging pipe as far
as it will go.
CAUTION:
Firmly secure the A/T fluid level gauge to the A/T fluid
charging pipe using the stopper attached.
f. Remove A/T fluid level gauge and note reading. If reading is at
low side of range, add A/T fluid to the A/T fluid charging pipe.
CAUTION:
Do not overfill.
4. Drive vehicle for approximately 5 minutes.
5. Re-check A/T fluid level at A/T fluid temperatures of 50 to 80°C (122 to 176°F) using “HOT” range on A/T
fluid level gauge.
CAUTION:
When wiping the A/T fluid level gauge, always use lint-free cloth.
Firmly secure the A/T fluid level gauge to the A/T fluid charging pipe using the stopper attached.
6. Check A/T fluid condition and make any necessary repairs. If the A/T fluid smells burnt, contains frictional
material (clutches, bands, etc.), or if the A/T is repaired, overhauled, or replaced, inspect and clean the A/
T fluid cooler mounted in the radiator. Refer to TM-172, "
A/T Fluid Cooler Cleaning".
7. Install the removed A/T fluid level gauge into the A/T fluid charging pipe.
CAUTION:
Firmly secure the A/T fluid level gauge to the A/T fluid charging pipe using the stopper attached.
Changing A/T FluidINFOID:0000000001728294
1. Warm up A/T fluid.
2. Stop engine.
3. Drain A/T fluid by removing the drain plug from the transaxle.
4. Reinstall the drain plug and new gasket and tighten to the specified torque.
CAUTION:
Do not reuse drain plug gasket.
