TCM Self-Diagnosis Does Not ActivateINFOID:0000000001703354
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 the signal via CAN communication to the TCM.

Adjustment of A/T PositionINFOID:0000000001703359
Move selector lever from “P” position to “1” position. You should be able to feel the detents in each position. If
the detents cannot be felt or if the position indicator is improperly aligned, the control cable needs adjustment.
CAUTION:
Make sure that parking brake is applied before adjustment.
1. Remove the air duct assembly. Refer to EM-16
.
2. Remove the control cable nut (A) and control cable (1) and
place the manual lever (2) in the "P' position.
3. Place selector lever in “P” position.
4. Hold control cable (1) at the end and pull it with a force of 9.8 N
(approximately 1 kg, 2.2 lb). Release the control cable and tem-
porarily tighten control cable nut (A).
5. Tighten control cable nut (A) to the specified torque.
CAUTION:
Secure manual lever when tightening nut.
6. Move selector lever from “P” to “1” position again. Make sure that selector lever moves smoothly.
7. Check A/T position. Refer to AT-207, "
Checking of A/T Position".
8. Install air duct assembly. Refer to EM-16
.
Checking of A/T PositionINFOID:0000000001703360
1. Place selector lever in “P” position, and turn ignition switch ON (Do not start engine).
2. Make sure selector lever can be shifted to other than “P” position when brake pedal is depressed. Also
make sure selector lever can be shifted from “P” position only when brake pedal is depressed.
3. Move selector lever and check for excessive effort, sticking, noise or rattle.
4. Confirm selector lever stops at each position with the feel of engagement when it is moved through all the
positions. Check whether or not the actual position selector lever is in matches the position shown by the
shift position indicator and the transaxle.

TRANSAXLE ASSEMBLY
• When replacing an engine or transmission you must make sure any dowels are installed correctly
during re-assembly.
• Improper alignment caused by missing dowels may cause vibration, oil leaks or breakage of drive
train components.
• Do not reuse O-rings and copper washers. Refer to "COMPONENTS".
• When turning crankshaft, turn it clockwise as viewed from the front of the engine.
• When tightening the bolts for the torque converter while securing the crankshaft pulley bolt, be sure
to confirm the tightening torque of the crankshaft pulley bolt. Refer to EM-37
.
• After converter is installed to drive plate, rotate crankshaft several turns to check that transaxle
rotates freely without binding.
• When installing the torque converter to the transaxle measure dis-
tance A.
• Check the fitting of the dowel pins when installing the transaxle
assembly and the engine assembly.
: Dowel pin (2)
• When installing the transaxle to the engine, align the matching mark on the drive plate with the matching
mark on the torque converter.
• When securing the transaxle to the engine, attach the bolts in
accordance with the following standard.
