Diagnostic Procedure with Diagnostic Trouble Code (DTC)
Step
1 CHECK DTC.
2 CHECK HARNESS BETWEEN DRIVER'S
CONTROL CENTER DIFFERENTIAL CON-
TROL MODULE AND ACCELERATOR PED-
AL POSITION SENSOR.
1) Turn the ignition switch to OFF.
2) Disconnect the harness connectors of the
driver's control center differential control mod-
ule, ECM, and accelerator pedal position sen-
sor.
3) Measure resistance of the harness between
driver's control center differential control mod-
ule harness connector and the accelerator
pedal position sensor harness connector.
Connector & terminal
(B380) No. 2 — (B135) No. 2:
3 CHECK HARNESS BETWEEN DRIVER'S
CONTROL CENTER DIFFERENTIAL CON-
TROL MODULE AND ECM.
Measure resistance between the driver's con-
trol center differential control module harness
connector and the ECM harness connector.
Connector & terminal
(B380) No. 2 — (B136) No. 28:
4 CHECK HARNESS BETWEEN DRIVER'S
CONTROL CENTER DIFFERENTIAL CON-
TROL MODULE AND ACCELERATOR PED-
AL POSITION SENSOR.
Measure resistance of the harness between the
driver's control center differential control mod-
ule harness connector and the chassis ground
Connector & terminal
(B380) No. 2 — Chassis ground:
5 CHECK DRIVER'S CONTROL CENTER DIF-
FERENTIAL CONTROL MODULE INPUT
SIGNAL.
1) Connect all the connectors.
2) Connect the Subaru Select Monitor to the
data link connector.
3) Turn the ignition switch and run the Subaru
Select Monitor.
4) Read the data of "sub accelerator sensor
voltage" using the Subaru Select Monitor.
Check whether the data is within the specifica-
tion when the accelerator pedal is not pressed.

mode?
Is the resistance less than 1 Ω? Go to step 3.
Is the resistance less than 1 Ω? Go to step 4.
Is the resistance 1 MΩ or
more?
Does the data read 0.1 — 1.3
