Engine Does Not Start

CAUTION:

When the keyless access Control Module is replaced with a new unit, and the battery ground terminal is connected, it will become ignition ON. Also, if the battery is disconnected, it will resume to a condition with the battery cut off.
When the keyless access Control Module is replaced, registration of the immobilizer is required. For the relevant procedures, refer to the "REGISTRATION MANUAL FOR IMMOBILIZER" provided as a separate volume.

Step	Check	Yes	No
1 INITIALIZE STEERING LOCK. Place the shift lever in the Parking range. Operate the driver's door switch ON/OFF with the ignition switch OFF. Wait for 10 seconds. Place the access key on the driver's seat. Press the push button ignition switch while depressing the brake pedal.	Can the engine start?	The circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again. NOTE: In this case, temporary poor contact of connector, temporary open or short circuit of harness may be the cause.	Go to step 2
2 CHECK DTC. Read DTCs of «Keyless Access with Push Button Start» using the Subaru Select Monitor. Ref. to READ DIAGNOSTIC TROUBLE CODE (DTC)	Are any DTCs displayed?	Perform the diagnosis for the displayed DTCs. Ref. to LIST , List of Diagnostic Trouble Code (DTC).	Go to step 3
3 CHECK POWER SUPPLY SWITCHING. Place the access key on the driver's seat. Press the push button ignition switch without depressing the brake pedal.	When the switch is operated, does the <IG-OFF> → <ACC-ON> → <IG-ON> → <IG-OFF> change occur?	Go to step 4	Perform the diagnostics according to the symptom for power supply switching system in General Diagnostic Table. Ref. to POWER SUPPLY SWITCHING SYSTEM , INSPECTION, General Diagnostic Table.
4 CHECK CURRENT DATA. Place the access key on the driver's seat. Press the push button ignition switch while depressing the brake pedal. Using the Subaru Select Monitor, confirm the keyless access Control Module, the current data «STSW signal monitor» when pressing the push button ignition switch. Ref. to READ CURRENT DATA NOTE: If it is difficult to confirm, press the push button ignition switch for approximately five seconds longer.	Does the data change from OFF → ON?	Go to step 10	Except for MT model: Go to step 5 MT model: Go to step 7
5 CHECK CURRENT DATA. Check the keyless access Control Module, current data «Shift P Signal» using the Subaru Select Monitor. Ref. to READ CURRENT DATA	Is «ON» displayed in parking position, and «OFF» displayed in other positions?	Go to step 6	Go to step 11
6 CHECK CURRENT DATA. Confirm the keyless access Control Module, current data «Stop Light Switch» using the Subaru Select Monitor. Ref. to READ CURRENT DATA	Is «ON» displayed when brake pedal depressed, and «OFF» displayed when brake pedal not depressed?	Go to step 7	Go to step 13
7 CHECK CURRENT DATA. Confirm the keyless access Control Module, current data «Neutral SW/Clutch SW» using the Subaru Select Monitor. Ref. to READ CURRENT DATA	Is «ON» displayed in parking and neutral positions, and «OFF» displayed in other positions?	Go to step 8	Go to step 15
8 CHECK STEERING LOCK. Operate the push button ignition switch to perform the power supply switching and check steering lock condition during ACC-ON condition.	Is the steering lock in unlocked condition?	Go to step 9	Perform the diagnostics according to the symptom for steering lock system in General Diagnostic Table. Ref. to STEERING LOCK SYSTEM , INSPECTION, General Diagnostic Table.
9 CHECK KEYLESS ACCESS CONTROL MODULE. Turn the ignition switch to OFF. Disconnect the ECM connector. Using a tester, measure the voltage between the keyless access Control Module connector and chassis ground in the following procedures. Press the push button ignition switch with the brake pedal depressed. (Measure within 10 seconds.) Release the push button ignition switch from the condition of step 1 above. Connector & terminal (i241) No. 37 (+) - Chassis ground (-):	Does the value change from 1 V or less to +B-2 V or more in the step 1, and return to 1 V or less in the step 2?	Perform the diagnosis for engine system. Ref. to PROCEDURE , Diagnostics for Engine Starting Failure. Ref. to PROCEDURE , Diagnostics or Engine Starting Failure. Replace the keyless access Control Module.	Ref. to KEYLESS ACCESS CONTROL MODULE
10 CHECK CURRENT DATA. Connect the disconnected connectors. Confirm the keyless access Control Module, current data «Engine start permission request reception status» using the Subaru Select Monitor. Ref. to READ CURRENT DATA	Is "Reception" displayed with ignition switch ON, and "Not yet received" displayed in other positions?	Perform the diagnosis for engine system. Ref. to PROCEDURE , Diagnostics for Engine Starting Failure. Ref. to PROCEDURE , Diagnostics for Engine Starting Failure.	Replace the keyless access Control Module. Ref. to KEYLESS ACCESS CONTROL MODULE
11 CHECK "P" RANGE SWITCH. Turn the ignition switch to OFF. Disconnect the AT shift lever connector. Using a tester, check the continuity of "P" range switch. Terminals No. 1 - 2:	Does it change from Continuity ←→ No continuity according to shift lever operation?	Go to step 12	Replace the "P" range switch. Ref. to REMOVAL , AT Shift Lock Solenoid and "P" Range Switch.
12 CHECK HARNESS (OPEN CIRCUIT). Turn the ignition switch to OFF. Disconnect the keyless access Control Module connector. Using a tester, check continuity between the keyless access Control Module connector and the AT select lever connector, and between the AT select lever connector and chassis ground. Connector & terminal (i44) No. 1 - (i75) No. 8: (i44) No. 2 - Chassis ground:	Is there continuity?	Replace the keyless access Control Module. Ref. to KEYLESS ACCESS CONTROL MODULE	Repair or replace the harness.
13 CHECK STOP LIGHT SWITCH. Turn the ignition switch to OFF. Disconnect the stop light switch connector. Using a tester, check continuity of the stop light switch connector. Terminals No. 1 - No. 2:	Does it change from Continuity ←→ No continuity according to brake pedal operation?	Go to step 14	Replace the stop light switch. Ref. to REMOVAL , Stop Light Switch.
14 CHECK HARNESS (OPEN CIRCUIT). Turn the ignition switch to OFF. Using a tester, check continuity between the keyless access Control Module connector and the stop light switch connector, and between the stop light switch connector and fuse. Connector & terminal (i241) No. 31 - (B65) No. 2: (B65) No. 1 - F/B fuse No. 37:	Is there continuity?	Replace the keyless access Control Module. Ref. to KEYLESS ACCESS CONTROL MODULE	Repair or replace the harness.
15 CHECK INHIBITOR SWITCH. Check the inhibitor switch. Ref. to INSPECTION , Inhibitor Switch.	Is the check result OK?	Go to step 16	Replace the inhibitor switch. Ref. to REMOVAL , Inhibitor Switch.
16 CHECK HARNESS (OPEN CIRCUIT). Turn the ignition switch to OFF. Disconnect the inhibitor switch connector. Using a tester, measure the continuity between the keyless access Control Module connector and the inhibitor switch connector, and between the inhibitor switch connector and the starter motor. Connector & terminal Engine type: FB (i241) No. 34 - (B12) No. 1: (B12) No. 5 - Starter motor: Engine type: EZ (i241) No. 34 - (B12) No. 12: (B12) No. 11 - Starter motor:	Is there continuity?	Replace the keyless access Control Module. Ref. to KEYLESS ACCESS CONTROL MODULE	Repair or replace the harness.
