ELECTRICAL LOAD SIGNAL
DescriptionINFOID:0000000001693428
The electrical load signal (Headlamp switch signal, rear window defogger switch signal, etc.) is transferred
through the CAN communication line from BCM to ECM via IPDM E/R.

MALFUNCTION INDICATOR
MALFUNCTION INDICATOR
DescriptionINFOID:0000000001693444
The Malfunction Indicator (MI) is located on the combination meter.
The MI will light up when the ignition switch is turned ON without the
engine running. This is a bulb check.
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.
For details, refer to EC-630, "
Diagnosis Procedure".

VALUES ON THE DIAGNOSIS TOOL
Remarks:
 Specification data are reference values.
 Specification data are output/input values which are detected or supplied by the ECM at the connector.
*Specification data may not be directly related to their components signals/values/operations.
I.e. Adjust ignition timing with a timing light before monitoring IGN TIMING, because the monitor may show the
specification data in spite of the ignition timing not being adjusted to the specification data. this IGN TIMING
monitors the data calculated by the ECM according to the signals input from the camshaft position sensor and
other ignition timing related sensors.

Engine speed will not
rise more than 2,500 rpm
due to the fuel cutMalfunction indicator
lamp circuitWhen there is an open circuit on MI circuit, the ECM cannot warn the
driver by lighting up MI 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 are detected and demands the driver to repair the malfunction.EC-630

P2135Throttle position sensor The ECM controls the electric throttle control actuator in regulating the throttle opening in
order for the idle position to be within +10 degrees.
The ECM regulates the opening speed of the throttle valve to be slower than the normal
condition.
So, the acceleration will be poor.
P0605 ECM (When ECM calculation function is malfunctioning:)
ECM stops the electric throttle control actuator control, throttle valve is maintained at a
fixed opening (approx. 5 degrees) by the return spring.
ECM deactivates ASCD operation.
P1121 Electric throttle control ac-
tuator(When electric throttle control actuator does not function properly due to the return spring
malfunction:)
ECM controls the electric throttle actuator by regulating the throttle opening around the
idle position. The engine speed will not rise more than 2,000 rpm.
(When throttle valve opening angle in fail-safe mode is not in specified range:)
ECM controls the electric throttle control actuator by regulating the throttle opening to 20
degrees or less.
(When ECM detects the throttle valve is stuck open:)
While the vehicle is driving, it slows down gradually by fuel cut. After the vehicle stops, the
engine stalls.
The engine can restart in P or N (A/T), Neutral (M/T) position, and engine speed will not
exceed 1,000 rpm or more.
