Introduction
The purpose of the bulletin is for information purposes when diagnosing DTC P0607. The following checks and information is in addition to what is
listed in the Subaru Service Manual. This information is to be used in

Repair Procedure/Information
Additional items to check:

Rapid drop of voltage from a dead battery
^
Loose battery terminals
^
Loose ECM ground terminal
^
A short or open to the power or ground circuit
If the malfunction criteria are met, the CEL will illuminate, the vehicle will go into fail safe and the throttle valve opening will be fixed at 6°. Fail safe
will recover to normal mode if the ECM judges the criteria "OK" at the time of the next engine start. The CEL will not turn off until the "OK" driving
cycle is completed 3 times in a row. The judgment is decided by the ECM to keep the CEL On or Off at the time the ignition switch is turned from ON to
OFF. The ECM keeps DTC P0607 in memory even after the indicator light goes out. Therefore, it is important to erase memory after the repair is
completed.
