DTC P1124, P1126 THROTTLE CONTROL MOTOR RELAY
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
EBS00QZV
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.

Refer to Wiring Diagram.
3.
Also check harness for short to ground and short to power.
OK or NG
OK
>> GO TO 5.
NG
>> GO TO 4.
4.
DETECT MALFUNCTIONING PART
Check the following.
●
Harness connectors E105, M10
●
Harness connectors M71, F45
●
Harness for open or short between ECM and throttle control motor relay
>> Repair open circuit or short to ground or short to power in harness or connectors.
5.
CHECK THROTTLE CONTROL MOTOR RELAY OUTPUT SIGNAL CIRCUIT
1.
Check continuity between ECM terminal 104 and throttle control motor relay terminal 1.
Refer to Wiring Diagram.
2.
Also check harness for short to ground and short to power.
OK or NG
OK
>> GO TO 7.
NG
>> GO TO 6.
6.
DETECT MALFUNCTIONING PART
Check the following.
●
Harness connectors E106, M11 (LHD models)
●
Harness connectors E145, M80 (RHD models)
●
Harness for open or short between ECM and throttle control motor relay
