Vehicle Does Not Decelerate by Engine BrakeINFOID:0000000005397411
SYMPTOM:
• Vehicle does not decelerate by engine brake when shifting from 22 (12 ) to 11“Cruise Test — Part 3”.
• Vehicle does not decelerate by engi ne brake when OD OFF (OD OFF indicator lamp is on) on “Cruise
Test — Part 3”.

Test — Part 3”.
DIAGNOSTIC PROCEDURE
1.CHECK CAN COMMUNICATION LINE
Perform self-diagnosis. Refer to AT-77, "
CONSULT-III Function (TRANSMISSION)" or AT-82, "Diagnosis Pro-
cedure without CONSULT-III" .
Is a malfunction in CAN communication indicated in the results?
YES >> Check CAN communication line. Refer to AT- 8 7 .
NO >> GO TO 2.
2.CHECK OVERDRIVE CO NTROL SWITCH CIRCUIT
With CONSULT-III
1. Turn ignition switch ON. (Do not start engine)
2. Select “TCM INPUT SIGNALS” in “DATA MONI TOR” mode for “TRANSMISSION” with CONSULT-III.
3. Read out “OVERDRIVE SW”.
Check the signal of the overdrive control switch is indicated properly.

TCM Self-Diagnosis Does Not ActivateINFOID:0000000005397412
SYMPTOM:
OD OFF indicator lamp does not come on in TCM sel f-diagnostic procedure even if the lamp circuit is
good.
DESCRIPTION
• Transmission range switch (1) Transmission range switch assembly includes a transaxle position
switch. The transaxle position swit ch 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.
