Malfunction Indicator (MI)EBS0036Q
DESCRIPTION
The MI is located on the instrument panel.
1. The MI will light up when the ignition switch is turned ON without
the engine running. This is a bulb check.
lIf the MI does not light up, refer toDI-39, "WARNING LAMPS"
or seeEC-825.
2. When the engine is started, the MI should go off.
If the MI remains on, the on board diagnostic system has
detected an engine system malfunction.
On Board Diagnostic System Function
The on board diagnostic system has the following two functions.
Diagnostic Test Mode I - Bulb Check
In this mode, the MI on the instrument panel should stay ON. If it remains OFF, check the bulb. Refer toDI-39,
"WA RN ING LA MPS"or seeEC-825.

"MI&DATA LINK CONNECTORS".)
Engine running MALFUNCTION
WARN IN GThis is a usual driving condition. When ECM detects a mal-
function, the MI will light up to inform the driver that a mal-
function has been detected.
MI Condition
ON When the malfunction is detected or the ECM's CPU is malfunctioning.
OFF No malfunction.

GLOW CONTROL SYSTEM
7.CHECK GLOW INDICATOR LAMP OUTPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1. Turn ignition switch “OFF”.
2. Disconnect ECM harness connector.
3. Check harness continuity between ECM terminal D2 and combination meter terminal 65 or 55. Refer to
Wiring Diagram.
4. Also check harness for short to ground and short to power.
OK or NG
OK >> GO TO 9.
NG >> GO TO 8.
8.DETECT MALFUNCTIONING PART
Check the following.
lHarness connectors M63, F30
lHarness for open or short between combination meter and ECM
>> Repair open circuit or short to ground or short to power in harness or connectors.
9.CHECK COMBINATION METER
Check combination meter and glow indicator lamp. Refer toDI-4, "
COMBINATION METERS (LHD MODELS)"
orDI-22, "COMBINATION METERS (RHD MODELS)"andDI-39, "WARNING LAMPS".
OK or NG
OK >> GO TO 17.
NG >> Repair or replace combination meter or glow indicator lamp.
10.CHECK GLOW RELAY POWER SUPPLY CIRCUIT
1. Turn ignition switch “OFF”.
2. Disconnect glow relay.
3. Check voltage between glow relay terminals 1, 3 and ground
with CONSULT-II or tester.
OK or NG
OK >> GO TO 12.
NG >> GO TO 11.Continuity should exist.
