Engine Control Module (ECM)

On «Main Menu» display, select {Each System Check}.
On «System Selection Menu» display, select {Engine Control System}. Click the [OK] button after the information of engine type has been displayed.
Drive vehicle at 40 km/h (25 MPH) or more and set the cruise control.
CAUTION:
- When performing diagnosis, observe the legal speed limit on the road.
- The cancel code will also appear when the cruise control is cancelled by the driver's operation. Do not confuse them.
- Be sure to get an assistant to support the diagnosis while driving, and have him/her operate the select monitor.
When the set speed is cancelled by itself (without any cancel operations such as applying brake) or when the cruise control could not be set by performing the setting operation, select the {Cancel Code(s) Display} on the engine malfunction diagnosis screen.
NOTE: The cancel code has a {Latest Diagnostic Code(s)} and {Memorized Diagnostic Code(s)}. {Latest Diagnostic Code(s)} displays the latest code that occurred in this check drive, and {Memorized Diagnostic Code(s)} displays the code recorded in the previous driving condition. Cancel codes by the diagnosis of faulty switches relating to the system and cruise control are also displayed in the {Memorized Diagnostic Code(s)}.
Perform Engine DTC Clear Memory operation. Cancel codes for switches relating to the system and cruise control are deleted by clearing memory on the engine side.
NOTE:
- The latest code will be cleared by turning ignition switch to OFF.
- For detailed operation procedures, refer to "PC application help for Subaru Select Monitor".
- For details on cancel codes, refer to List of Cancel Code. < Refer to ECM , LIST, List of Cancel Code. >
