Number Item Description
1 Power conditionThis shows the condition when the system receives battery positive voltage (can be
operated).
2 Fusible linkThe double line shows that this is a fusible link.
The open circle shows current flow in, and the shaded circle shows current flow out.
3Fusible link/fuse loca-
tionThis shows the location of the fusible link or fuse in the fusible link or fusebox.For
arrangement, refer to EL-12, “POWER SUPPLY ROUTING”.
4FuseThe single line shows that this is a fuse.
The open circle shows current flow in, and the shaded circle shows current flow out.
5 Current rating This shows the current rating of the fusible link or fuse.
6 ConnectorsThis shows that connector E3 is female and connector M1 is male.
The G/R wire is located in the 1A terminal of both connectors.
Terminal number with an alphabet (1A, 5B, etc.) indicates that the connector is SMJ con-
nector. Refer to GI-20.
7 Optional splice The open circle shows that the splice is optional depending on vehicle application.
8 Splice The shaded circle shows that the splice is always on the vehicle.
9 Page crossingThis arrow shows that the circuit continues to an adjacent page.
The A will match with the A on the preceding or next page.
10 Common connectorThe dotted lines between terminals show that these terminals are part of thesamecon-
nector.
11 Option abbreviation This shows that the circuit is optional depending on vehicle application.
12 RelayThis shows an internal representation of the relay. For details, refer to EL-9, “STAN-
DARDIZED RELAY”.

ON BOARD DIAGNOSTIC (OBD) SYSTEM
When there is an open circuit on MI circuit, the ECM cannot warn the driver by lighting MI up when there is
malfunction on engine control system.
Therefore, when electrical controlled throttle and part of ECM related diagnoses are continuously detected as
NG for 5 trips, ECM warns the driver that engine control system malfunctions and MI circuit is open by means
of operating fail-safe function.
The fail-safe function also operates when above diagnoses except MI circuit and demands the driver to repair
the malfunction.
MI Flashing without DTC
If the ECM is in Diagnostic Test Mode II, MI may flash when engine is running. In this case, check ECM diag-
nostic test mode, EC-51, "
HOW TO SWITCH DIAGNOSTIC TEST MODE" .
How to switch the diagnostic test (function) modes, and details of the above functions are described later, EC-
51, "HOW TO SWITCH DIAGNOSTIC TEST MODE" .
The following emission-related diagnostic information is cleared when the ECM memory is erased.

WARNINGThis is a usual driving condition. When a malfunction is
detected twice in two consecutive driving cycles (two trip
detection logic), the MI will light up to inform the driver that
a malfunction has been detected.
The following malfunctions will light up or blink the MI in
the 1st trip.

Malfunction Indicator (MI)ECS007NR
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 EC-397
or EC-715 .
(Or see MI & CONSULT-II in EC section. Refer to EC-49
, EC-
87 .
2. When the engine is started, the malfunction indicator should
turned OFF.
If the lamp remains ON, the on board diagnostic system has
detected an emission-related (EURO-OBD) malfunction. For
detail, refer to EC-36.
CONSULT-IIECS007NS
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 valve).
Check for time difference between actual shift timing and the CONSULT-II display. If the difference is
noticeable, mechanical parts (except solenoid valves, 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 EL-11, "POWER SUPPLY ROUTING".
2. Touch “SELF DIAGNOSIS”.
Display shows malfunction experienced since the last erasing
operation.
CONSULT-II performs “real time diagnosis”.
Also, any malfunction detected while in this mode will be dis-
played at real time.
