HOW TO ERASE DTC (WITH CONSULT-II)
NCAT0020S03
I
If a DTC is displayed for both ECM and TCM, it needs to be erased for both ECM and TCM.
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. Turn CONSULT-II “ON” and touch “CVT”.
3. Touch “SELF-DIAG RESULTS”.
4. Touch “ERASE”. (The DTC in the TCM will be erased.) Then touch “BACK” twice.
5. Touch “ENGINE”.
6. Touch “SELF-DIAG RESULTS”.
7. Touch “ERASE”. (The DTC in the ECM will be erased.)

HOW TO ERASE DTC (WITH GST)
NCAT0020S04
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 “OBD SELF-DIAGNOSTIC PROCEDURE (No Tools)”. Refer to AT-25. (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 section “Generic Scan Tool (GST)”.
HOW TO ERASE DTC (NO TOOLS)
NCAT0020S05
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-25. (The engine warm-up step
can be skipped when performing the diagnosis only to erase the DTC.)
3. Change the diagnostic test mode from Mode II to Mode I by turning the mode selector on the ECM.
Refer to EC section “HOW TO SWITCH DIAGNOSTIC TEST MODES”.
Malfunction Indicator (MI)
NCAT0021
1.
The malfunction indicator will light up when the ignition switch
is turned ON without the engine running. This is for checking
the lamp.
I
If the malfunction indicator does not light up, refer to EL sec-
tion
(“Warning
Lamps/System
Description”,
“WARNING
LAMPS AND CHIME”).
(Or see MI & Data Link Connectors in EC section.)
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 (OBD) malfunction. For detail,
refer to EC section (“ON BOARD DIAGNOSTIC SYSTEM
DESCRIPTION”).
CONSULT-II
NCAT0022
After performing “SELF-DIAGNOSTIC PROCEDURE (WITH CON-
SULT-II)” (AT-19), place check marks for results on the “DIAGNOS-
TIC WORKSHEET”, AT-31. Reference pages are provided follow-
ing the items.
NOTICE:
I
Additional CONSULT-II information can be found in the Opera-
tion Instruction supplied with the CONSULT-II unit.

SELF-DIAGNOSTIC PROCEDURE
(WITH CONSULT-II)
NCAT0022S02
1.
Turn on CONSULT-II and touch “ENGINE” for OBD detected
items or touch “CVT” for TCM self-diagnosis.
If CVT is not displayed, check TCM power supply and ground
circuit. Refer to AT-41. If result is NG, refer to EL section
(“POWER SUPPLY ROUTING”).
2.
Touch “SELF DIAGNOSIS”.
Display shows malfunction experienced since the last erasing
operation.
CONSULT-II performs REAL-TIME SELF-DIAGNOSIS.
Also, any malfunction detected while in this mode will be dis-
played at real time.
