TCM Self-Diagnosis Does Not ActivateECS004TE
SYMPTOM:
O/D OFF indicator lamp does not come on in TCM self-diagnostic procedure even if the lamp circuit is
good.
DESCRIPTION

PNP switch
The 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
Detects the overdrive control switch position (ON or OFF) and
sends a signal to the TCM.

Closed throttle position signal and wide open throttle position
signal
ECM judges throttle opening based on a signal from accelerator
pedal position sensor, and sends the signal via CAN communi-
cation to TCM.

properly.
OK or NG
OK >> GO TO 3.
NG >> Check the following items:

PNP switch (Refer to AT- 2 4 0 , "COMPONENT
INSPECTION" .)

Harness for short or open between ignition switch and
PNP switch

Harness for short or open between PNP switch and
TCM

Diode (P, N positions)
2. CHECK PNP SWITCH CIRCUIT (WITHOUT CONSULT-II)
Without CONSULT-II
1. Turn ignition switch to ON. (Do not start engine.)
2. Check voltage between TCM terminals 26, 27, 34, 35, 36 and
ground while moving selector lever through each position.
OK or NG
OK >> GO TO 3.
NG >> Check the following items:

(Overdrive control switch ON displayed on CONSULT-II means
overdrive OFF.)
OK or NG
OK >> GO TO 4.
NG >> Check the following items:

Overdrive control switch (Refer to AT- 2 4 0 , "COMPO-
NENT INSPECTION" .)

Harness for short or open between Combination
meter and overdrive control switch

(WITH CONSULT-II)
With CONSULT-II
1. Turn ignition switch to ON. (Do not start engine.)
2. Select “TCM INPUT SIGNALS” in “DATA MONITOR” mode for “A/T” with CONSULT-II.
3. Read out “CLOSED THL/SW” and “W/O THRL-SW” depressing and releasing accelerator pedal.
Check the signal of throttle position signal is indicated properly.
OK or NG
OK >> GO TO 5.
NG >> Check the following items. If any items are damaged, repair or replace damaged parts.

Accelerator pedal position sensor — Refer to AT- 1 7 3 , "DTC P1705 ACCELERATOR PEDAL

After performing AT- 2 4 2 , "SELF-DIAGNOSTIC PROCEDURE (WITH CONSULT-II)" , place check marks for
results on the AT- 2 5 2 , "
DIAGNOSTIC WORKSHEET" . Reference pages are provided following the items.
NOTICE:
1. The CONSULT-II electrically displays shift timing and lock-up timing (that is, operation timing of each sole-
noid).
Check for time difference between actual shift timing and the CONSULT-II display. If the difference is
noticeable, mechanical parts (except solenoids, sensors, etc.) may be malfunctioning. Check mechanical
parts using applicable diagnostic procedures.
2. Shift schedule (which implies gear position) displayed on CONSULT-II and that indicated in Service Man-
ual may differ slightly. This occurs because of the following reasons:
–Actual shift schedule has more or less tolerance or allowance,
–Shift schedule indicated in Service Manual refers to the point where shifts start, and
–Gear position displayed on CONSULT-II indicates the point where shifts are completed.
3. Shift solenoid valve “A” or “B” is displayed on CONSULT-II at the start of shifting. Gear position is dis-
played upon completion of shifting (which is computed by TCM).
4. Additional CONSULT-II information can be found in the Operation Manual supplied with the CONSULT-II
unit.
FUNCTION
SELF-DIAGNOSTIC PROCEDURE (WITH CONSULT-II)
1. Turn on CONSULT-II and touch “A/T” for TCM self-diagnosis.
If A/T is not displayed, check TCM power supply and ground cir-
cuit. Refer to AT- 2 8 6 , "
TCM Terminals and Reference Value" . If
result is NG, refer to PG-2, "
POWER SUPPLY ROUTING" .
