Trunk Will Not Open With Keyless Access

WARNING: This page is about a different car, the 2016 Subaru Outback and 2016 Subaru Legacy. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
  • Check that there are no other registered access keys inside the trunk.
  • Inspect LAN system according to the basic diagnostic procedure, and make sure that there is no fault.
  • Check that the keyless access function is not stopped.
  • When the access key or 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.
DIAGNOSTICS PROCEDURE

Step Check Yes No
1 CHECK TRUNK OPENER BUTTON. 
Check that the trunk opens with the driver's seat trunk opener button.		 Does it open normally? Go to step 2  . Check the door lock circuit. < Ref. to SYMPTOM CHART , INSPECTION, Door Lock Control System. >
2 CHECK KEYLESS OPERATION. 
Check that the trunk opens when the trunk opener button of the access key is operated.		 Does it open normally? Go to step 9  . Go to step 3  .
3 CHECK TRUNK UNLOCK OPERATION. 
  1. Using the Subaru Select Monitor, select the function check «R gate/trunk UNLK output» of the body integrated unit. < Ref. to FUNCTION CHECK . >
  2. Check that the trunk opens when the R gate/trunk UNLK signal is output.
 Does it open normally? Go to step 7  . Go to step 4  .
4 CHECK WIRING HARNESS. 
  1. Disconnect the body integrated unit connector and trunk lid lock actuator connector.
  2. Check the continuity between body integrated unit connector and trunk lid lock actuator connector.

    Connector & terminal 

    (i266) No. 7 - (R186) No. 1: 

 Is there continuity? Go to step 5  . Repair or replace the open circuit of harness.
5 CHECK WIRING HARNESS. 
Check the continuity between the trunk lid lock actuator connector and chassis ground.
Connector & terminal 
(R186) No. 2 - Chassis ground: 		 Is there continuity? Go to step 6  . Repair or replace the open circuit of harness.
6 CHECK TRUNK LID LOCK ACTUATOR. 
Check the trunk lid lock actuator. < Ref. to TRUNK LID LATCH AND ACTUATOR ASSEMBLY . >		 Is trunk lid actuator normal? Replace the body integrated unit. < Ref. to BODY INTEGRATED UNIT . > Replace the trunk lid latch & actuator assembly. < Ref. to TRUNK LID LATCH AND ACTUATOR ASSEMBLY . >
7 CHECK ACCESS KEY.

  2. Check that the trunk opens with each access key.
 Does it open normally? Go to step 9  . Replace the access key. < Ref. to REPLACEMENT , Access Key. >
9 CHECK CURRENT DATA. 
  1. Display the current data «Trunk Request SW» of «Keyless access with push button start» using Subaru Select Monitor. < Ref. to READ CURRENT DATA . >
  2. Read the data when pressing the trunk opener button.
 Does the data display ON? Go to step 13  . Go to step 10  .
10 CHECK WIRING HARNESS. 
  1. Disconnect the trunk opener button connector and the keyless access control module connector.
  2. Using a tester, check continuity between the trunk opener button connector and keyless access control module connector.

    Connector & terminal 

    (R294) No. 2 - (i241) No. 24: 

 Is there continuity? Go to step 11  . Repair or replace the open circuit of harness.
11 CHECK WIRING HARNESS. 
  1. Using a tester, check the continuity between the trunk opener button connector and chassis ground.

    Connector & terminal 

    (R294) No. 1 - Chassis ground: 

 Is there continuity? Go to step 12  . Repair or replace the open circuit of harness.
12 CHECK TRUNK OPENER BUTTON. 
Using a tester, check the continuity between trunk opener button connector terminals.
Connector & terminal 
(R294) No. 1 - No. 2: 		 Is there continuity when pressing the switch? Go to step 13  . Replace the trunk opener button. < Ref. to TRUNK OPENER BUTTON . >
13 CHECK WIRING HARNESS. 
  1. Disconnect the exterior rear antenna connector and the keyless access control module connector.
  2. Using a tester, check continuity between the exterior rear antenna connector and keyless access control module connector.

    Connector & terminal 

    (R299) No. 1 - (i241) No. 16: 

    (R299) No. 3 - (i241) No. 15: 

 Is there continuity? Go to step 14  . Repair or replace the open circuit of harness.
14 CHECK OUTSIDE REAR ANTENNA. 
Replace the outside rear antenna with new or properly working parts.		 Does it operate properly? Replace the outside rear antenna. < Ref. to REMOVAL , Keyless Access Outdoor Antenna. > Go to step 15  .
15 CHECK KEYLESS ACCESS SYSTEM CHECK. 
  1. Using the Subaru Select Monitor, select System check of «Keyless access with push button start»: «Trunk external transmitter + interior tuner». < Ref. to KEYLESS ACCESS SYSTEM CHECK . >
  2. Hold the access key 1 m or more away from the trunk, then come closer to within 0.8 m.
 Does the outside buzzer sound? The circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again.
