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.

STALL TEST
8. Move selector lever to “N” position.
9. Cool off ATF.
CAUTION:
Run the engine at idle for at least 1 minute.
10. Repeat steps 6 through 9 with selector lever in “2”, “1” and “R”
positions.
JUDGEMENT OF STALL TEST
The test result and possible damaged components relating to each result are shown in the illustrations on next
page.
In order to pinpoint the possible damaged components, refer to XX-XX, "*****"
.
NOTE:
Stall revolution is too high in “D”, “2”, or “1” position:
Slippage occurs in 1st gear but not in 2nd and 3rd gears. ..... Low one-way clutch slippage
Slippage occurs in the following gears:
1st through 3rd gears in “D” position and engine brake functions with OD OFF. (OD OFF indicator lamp is
on.)
1st and 2nd gears in “2” position and engine brake functions with accelerator pedal released (fully closed
throttle)...... Forward clutch or forward one-way clutch slippage
Stall revolution is too high in “R” position:
Engine brake does not function in “1” position. ..... Low & reverse brake slippage
Engine brake functions in “1” position. ..... Reverse clutch slippage
Stall revolution within specifications:
Vehicle does not achieve speed of more than 80 km/h (50 MPH). ..... One-way clutch seizure in torque con-
verter housing
CAUTION:
Be careful because automatic fluid temperature increases abnormally:
Slippage occurs in 3rd and 4th gears in “D” position. ..... High clutch slippage
Slippage occurs in 2nd and 4th gears in “D” position. ..... Brake band slippage
Engine brake does not function in 2nd and 3rd gears in “D” position, 2nd gear in “2” position, and 1st gear in
“1” position with OD OFF. (OD OFF indicator lamp is on.) ..... Overrun clutch slippage
Stall revolution less than specifications:
Poor acceleration during starts. ..... One-way clutch seizure in torque converter
