Diagnostic ProcedureECS004TO
1.CHECK INPUT SIGNAL
With CONSULT-II
1. Start engine.
2. Select “TCM INPUT SIGNALS” in “DATA MONITOR” mode for “A/T” with CONSULT-II.
3. Read out the value of “VHCL/S SE·MTR” while driving.
Check the value changes according to driving speed.
Without CONSULT-II
1. Start engine.
2. Check voltage between TCM terminal 40 and ground while driv-
ing at 2 to 3 km/h (1 to 2 MPH) for 1 m (3 ft) or more.
OK or NG
OK >> GO TO 2
NG >> Check the following items. If any items are damaged, repair or replace damaged parts.
●Combination meter
Refer to DI-4, "
COMBINATION METERS (LHD MODELS)" or DI-24, "COMBINATION
METERS (RHD MODELS)" .
●Harness for short or open between TCM and combination meter
●4WD/ABS control unit
Refer to BRC-24, "
SELF-DIAGNOSIS" .
●Harness for short or open between 4WD/ABS control unit and combination meter
2.CHECK DTC
Perform Self-diagnosis Code confirmation procedure, AT- 3 5 8 , "
SELF-DIAGNOSIS CODE CONFIRMATION
PROCEDURE" .
OK or NG
OK >>INSPECTION END
NG >> 1. Perform TCM input/output signal inspection.
2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector. Voltage: Voltage varies between less than 1V and
more than 4.5V.

DescriptionECS004TP
●Accelerator pedal position (APP) sensor
Electric throttle control actuator consists of throttle control motor,
acceleration pedal position sensor, throttle position sensor, etc.
The actuator sends a signal to the TCM.

SELF-DIAGNOSIS CODE CONFIRMATION PROCEDURE
After the repair, perform the following procedure to confirm the malfunction is eliminated.
With CONSULT-II
1. Start engine.
2. Select “SELF-DIAG RESULTS” mode for A/T with CONSULT-II.
3. Drive vehicle under the following conditions:
Selector lever in “D” position, vehicle speed higher than 10 km/h
(6 MPH), throttle opening greater than 1/2 of the full throttle
position and driving for more than 3 seconds.
Without CONSULT-II
1. Start engine.
2. Drive vehicle under the following conditions:
Selector lever in “D” position, vehicle speed higher than 10 km/h
(6 MPH), throttle opening greater than 1/2 of the full throttle
position and driving for more than 3 seconds.
3. Perform self-diagnosis.

Diagnostic ProcedureECS004TR
1.CHECK DTC WITH ECM
●Check P code with CONSULT-II “ENGINE”.
Turn ignition switch ON and select “SELF DIAGNOSTIC RESULTS” mode for “ENGINE” with CONSULT-II.
Refer to EC-457, "
Malfunction Indicator (MI)" (QR25DE) or EC-1144, "Malfunction Indicator (MI)" (QR20DE).
OK or NG
OK (With CONSULT-II)>>GO TO 2.
OK (Without CONSULT-II)>>GO TO 3.
NG >> Check throttle position sensor circuit for engine control.
2.CHECK INPUT SIGNAL (WITH CONSULT-II)
With CONSULT-II
1. Turn ignition switch to “ON” position.
(Do not start engine.)
2. Select “TCM INPUT SIGNALS” in “DATA MONITOR” mode for
“A/T” with CONSULT-II.
3. Read out the value of “THRTL POS SEN”.
OK or NG
OK >> GO TO 4.
NG >> Check harness for short or open between ECM and
TCM regarding throttle position sensor circuit.
