7. Touch “ERASE”. (The DTC in the ECM will be erased.)
HOW TO ERASE DTC (WITH GST)
1. If the ignition switch stays “ON” after repair work, be sure to turn ignition switch “OFF” once. Wait at least
5 seconds and then turn it “ON” (engine stopped) again.
2. Perform “TCM SELF-DIAGNOSTIC PROCEDURE (NO TOOLS)”. Refer to AT- 5 1
. (The engine warm-up
step can be skipped when performing the diagnosis only to erase the DTC.)
3. Select Mode 4 with Generic Scan Tool (GST). For details, refer to EC-104, "
Generic Scan Tool (GST)
Function" (QR25DE) or EC-836, "Generic Scan Tool (GST) Function" (QR20DE).
HOW TO ERASE DTC (NO TOOLS)

5 seconds and then turn it “ON” (engine stopped) again.
2. Perform “TCM SELF-DIAGNOSTIC PROCEDURE (NO TOOLS)”. Refer to AT- 5 1
. (The engine warm-up

Malfunction Indicator lamp (MIL)ECS004QL
1. The malfunction indicator lamp will light up when the ignition
switch is turned ON without the engine running. This is for
checking the lamp.
●If the malfunction indicator does not light up, refer to DI-43,
"Schematic" .
(Or see MIL & CONSULT-II in EC section. Refer to EC-58,
"Malfunction Indicator (MI)" (QR25DE) or EC-790, "Malfunc-
tion Indicator (MI)" (QR20DE), EC-94, "CONSULT-II Func-
tion" (QR25DE) or EC-826, "CONSULT-II Function"
(QR20DE).
2. When the engine is started, the malfunction indicator should go
off.
If the lamp remains on, the on board diagnostic system has detected an emission-related (EURO-OBD)
malfunction. For detail, refer to EC-44, "
ON BOARD DIAGNOSTIC (OBD) SYSTEM" (QR25DE) or EC-
777, "ON BOARD DIAGNOSTIC (OBD) SYSTEM" (QR20DE).
CONSULT-IIECS004QM
After performing “SELF-DIAGNOSTIC PROCEDURE (WITH CONSULT-II)” AT- 4 1 , place check marks for
results on the “DIAGNOSTIC WORKSHEET”, AT- 5 7
. 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.
SELF-DIAGNOSTIC PROCEDURE (WITH CONSULT-II)
1. Turn on CONSULT-II and touch “ENGINE” for EURO-OBD
detected items or touch “A/T” for TCM self-diagnosis.
If A/T is not displayed, check TCM power supply and ground cir-
cuit. Refer to AT- 1 0 6 , "
TCM Terminals and Reference Value" . If
result is NG, refer to PG-2, "
POWER SUPPLY ROUTING" .
