Subaru Select Monitor

A: OPERATION

1. HOW TO USE THE SUBARU SELECT MONITOR

For the operation procedure, refer to the "PC application help for Subaru Select Monitor".

2. READ DIAGNOSTIC TROUBLE CODE (DTC) FOR ENGINE AND BODY INTEGRATED UNIT

Refer to "Read Diagnostic Trouble Code" for information about how to indicate DTC. <Ref. to IM(diag)- 9, Read Diagnostic Trouble Code (DTC).>

3. COMMUNICATION LINE CHECK

The communication line between ECM and body integrated unit can be checked in "System Operation Check Mode". This is referred to as "Communication line check".

For the operation procedure, refer to the "PC application help for Subaru Select Monitor".

NOTE: If a problem is detected, repair the trouble cause.

<Ref. to IM(diag)-20, DTC P1572 IMM CIRCUIT FAILURE (EXCEPT ANTENNA CIRCUIT), Diagnostic Procedure with Diagnostic Trouble Code (DTC).>

Read Diagnostic Trouble Code (DTC)

A: OPERATION

1. ECM

For the operation procedure, refer to the "PC application help for Subaru Select Monitor".

NOTE: For detailed concerning DTC, refer to the List of Diagnostic Trouble Codes (DTC). <Ref. to IM(diag)- 14, LIST, List of Diagnostic Trouble Code (DTC).>

2. BODY INTEGRATED UNIT

For the operation procedure, refer to the "PC application help for Subaru Select Monitor".

NOTE: For detailed concerning DTC, refer to the List of Diagnostic Trouble Codes (DTC). <Ref. to IM(diag)- 14, LIST, List of Diagnostic Trouble Code (DTC).>

Clear Memory Mode

A: OPERATION

1. ECM

For the operation procedure, refer to the "PC application help for Subaru Select Monitor".

NOTE: Initial diagnosis of electronic throttle control is performed after memory clearance. Wait for 10 seconds or more after turning the ignition switch to ON, and then start the engine.

2. BODY INTEGRATED UNIT

List of Diagnostic Trouble Code (DTC)

A: LIST

1. ECM

Subaru Outback. Immobilizer (Diagnostics)

NOTE: Perform diagnosis of engine DTC when a DTC other than an immobilizer DTC is detected. <Ref. to EN(H4SO)(diag)-78, List of Diagnostic Trouble Code (DTC).> <Ref. to EN(H4DOTC)(diag)-75, List of Diagnostic Trouble Code (DTC).> <Ref. to EN(H6DO)(diag)-85, List of Diagnostic Trouble Code (DTC).>

2. BODY INTEGRATED UNIT

Subaru Outback. Immobilizer (Diagnostics)

NOTE: The starter relay control is performed in immobilizer system. When the body integrated unit detects a nonconformity of reference code, it immediately outputs a starter relay cut signal to ECM, and then ECM stops the starter relay operation. In this case, engine does not start, and DTC is not recorded in ECM. Check that the engine does not start on the DTC of body integrated unit.
