Component Description
EBS00QZQ
Power supply for the Throttle Control motor is provided to the ECM via throttle control motor relay. The throttle
control motor relay is ON/OFF controlled by the ECM. When the ignition switch is turned ON, the ECM sends
an ON signal to throttle control motor relay and battery voltage is provided to the ECM. When the ignition
switch is turned OFF, the ECM sends an OFF signal to throttle control motor relay and battery voltage is not
provided to the ECM.
CONSULT-II Reference Value in Data Monitor Mode
EBS00QZR
Specification data are reference values.
On Board Diagnosis Logic
EBS00QZS
This self-diagnosis has the one trip detection logic.
FAIL-SAFE MODE
When the malfunction is detected, the ECM enters fail-safe mode and the MI lights up.
DTC Confirmation Procedure
EBS00QZT
NOTE:
If “DTC Confirmation Procedure” has been previously conducted, always turn ignition switch “OFF” and wait at
least 10 seconds before conducting the next test.
PROCEDURE FOR DTC P1124
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10V at idle.
With CONSULT-II
1.
Turn ignition switch “ON” and wait at least 1 second.
2.
Select “DATA MONITOR” mode with CONSULT-II.
3.
If DTC is detected, go to
EC-772, "Diagnostic Procedure"
.
