Engine Does Not Start

CAUTION:

When the keyless access CM (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 CM (Control Module) or ID code box is replaced, registration of the immobilizer is required. For the relevant procedures, refer to the "REGISTRATION MANUAL FOR IMMOBILIZER" provided as a separate volume.

DIAGNOSTIC PROCEDURE

Step	Check	Yes	No
1 INITIALIZE STEERING LOCK. Shift the shift lever to parking for CVT model, or to neutral for MT model. 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. With depressing the brake pedal (CVT model) or clutch pedal (MT model), push the push button ignition switch.	Can the engine start?	System is normal.	Go to step 2.
2 CHECK DTC. Read the DTC of the keyless access system using Subaru Select Monitor. < Ref. to READ DIAGNOSTIC TROUBLE CODE (DTC) . >	Is DTC detected?	Perform the diagnosis according to the DTC. < 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. Without depressing the brake pedal (CVT model) or clutch pedal (MT model), push the push button ignition switch.	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. With depressing the brake pedal (CVT model) or clutch pedal (MT model), push the push button ignition switch. Using the Subaru Select Monitor, confirm the keyless access CM (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.	CVT model: Go to step 5. MT model: Go to step 7.
5 CHECK CURRENT DATA. Check the keyless access CM (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 CM (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 CM (Control Module), current data «Neutral SW/Clutch SW» using the Subaru Select Monitor. < Ref. to READ CURRENT DATA . >	For CVT model, is ON displayed in parking and neutral position and OFF displayed in other positions? For MT model, is ON displayed when clutch pedal is depressed and OFF displayed when the pedal not depressed?	Go to step 8.	CVT model: Go to step 15. MT model: Go to step 16.
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 CM (Control Module). Turn the ignition switch to OFF. Disconnect the ECM connector. Using a tester, measure the battery voltage in following procedures. Press the push button ignition switch with the brake pedal depressed (MT model: clutch pedal depressed). (Measure within 10 seconds.) Release the push button ignition switch from the condition of step 1. above. Connector & terminal (B572) No. 13 (+) - 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 DIAGNOSTICS FOR ENGINE STARTING FAILURE . > < Ref. to PROCEDURE , Diagnostics for Engine Starting Failure. >	Replace the keyless access CM (Control Module). < Ref. to KEYLESS ACCESS CM (Control Module) . >
10 CHECK CURRENT DATA. Connect the disconnected connectors. Confirm the keyless access CM (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 DIAGNOSTICS FOR ENGINE STARTING FAILURE . > < Ref. to PROCEDURE , Diagnostics for Engine Starting Failure. >	Replace the keyless access CM (Control Module). < Ref. to KEYLESS ACCESS CM (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. Connector & terminal (B116) 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. Turn the ignition switch to OFF. Disconnect the keyless access CM (Control Module) connector. Using a tester, check continuity between the keyless access CM (Control Module) and AT select lever. Connector & terminal (B116) No. 1 - (B574) No. 25: (B116) No. 2 - Chassis ground:	Is there continuity?	Replace the keyless access CM (Control Module). < Ref. to KEYLESS ACCESS CM (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 the continuity of the stop light switch. Connector & terminal (B65) 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. Turn the ignition switch to OFF. Using a tester, check continuity between the keyless access CM (Control Module) and stop light switch. Connector & terminal (B572) No. 18 - (B65) No. 2: (B65) No. 1 - F/B fuse No. 8:	Is there continuity?	Replace the keyless access CM (Control Module). < Ref. to KEYLESS ACCESS CM (Control Module) . >	Repair or replace the harness.
15 CHECK INHIBITOR SWITCH. Check the inhibitor switch. < Ref. to INSPECTION , Inhibitor Switch. >	Is the inhibitor switch working normal?	Go to step 17.	Replace the inhibitor switch. < Ref. to REMOVAL , Inhibitor Switch. >
16 CHECK CLUTCH SWITCH. Check the clutch switch. < Ref. to INSPECTION , Clutch Switch. >	Is clutch switch OK?	Go to step 18.	Replace the clutch switch. < Ref. to REMOVAL , Clutch Switch. >
17 CHECK HARNESS. Turn the ignition switch to OFF. Disconnect the inhibitor switch connector. Using a tester, check continuity between the keyless access CM (Control Module) connector and inhibitor switch connector. Connector & terminal (B572) No. 5 - (B12) No. 12: (B12) No. 11 - Starter motor:	Is there continuity?	Replace the keyless access CM (Control Module). < Ref. to KEYLESS ACCESS CM (Control Module) . >	Repair or replace the harness.
18 CHECK HARNESS. Turn the ignition switch to OFF. Disconnect the clutch switch connector. Using a tester, check continuity between the keyless access CM (Control Module) connector and clutch switch connector. Connector & terminal (B572) No. 10 - (B106) No. 2: (B106) No. 1 - F/B fuse No. 21:	Is there continuity?	Replace the keyless access CM (Control Module). < Ref. to KEYLESS ACCESS CM (Control Module) . >	Repair or replace the harness.
