DTC P1124, P1126 THROTTLE CONTROL MOTOR RELAY
DTC P1124, P1126 THROTTLE CONTROL MOTOR RELAY
PFP:16119
Component Description
EBS00QP9
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
EBS00QPA
Specification data are reference values.
On Board Diagnosis Logic
EBS00QPB
These self-diagnoses have the one trip detection logic.
FAIL-SAFE MODE
When the malfunction is detected, ECM enters fail-safe mode and the MI lights up.
DTC Confirmation Procedure
EBS00QPC
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-401, "Diagnostic Procedure"
.

Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
Diagnostic Procedure
EBS00QPE
1.
CHECK THROTTLE CONTROL MOTOR RELAY POWER SUPPLY CIRCUIT
1.
Turn ignition switch “OFF”.
2.
Disconnect throttle control motor relay.
3.
Check voltage between throttle control motor relay terminals 2, 5
and ground.
OK or NG
OK
>> GO TO 3.
NG
>> GO TO 2.
2.
DETECT MALFUNCTIONING PART
Check the following.
●
15A fuse
●
Harness for open or short between throttle control motor relay and fuse
>> Repair open circuit or short to ground or short to power in harness or connectors.
