Check Door Lock Actuator And Circuit
| Step | Check | Yes | No |
|---|---|---|---|
1 CHECK HARNESS (DOOR LOCK).
|
Is harness normal? | Go to step 2. | Repair or replace the harness. |
| 2 CHECK HARNESS (DOOR UNLOCK). Check the harness between body integrated unit connector and each door lock actuator connector. Connector & terminal Front door RH (i171) No. 3 - (D72) No. 2: Front door LH (i171) No. 4 - (D18) No. 2: Rear door RH (i171) No. 3 - (D32) No. 2: Rear door LH (i171) No. 3 - (D26) No. 2: |
Is harness normal? | OUTBACK model Go to step 3
. Sedan model: Go to step 5. |
Repair or replace the harness. |
| 3 CHECK HARNESS (REAR GATE UNLOCK). Check the harness between body integrated unit connector and rear gate lock actuator connector. Connector & terminal (i171) No. 7 - (D47) No. 1: |
Is harness normal? | Go to step 4. | Repair or replace the harness. |
| 4 CHECK HARNESS (REAR GATE UNLOCK). Measure the resistance between the rear gate lock actuator connector and chassis ground. Connector & terminal (D47) No. 2 - Chassis ground: |
Is the resistance less than 10 Ω? | Go to step 7. | Repair or replace the harness. |
| 5 CHECK HARNESS (TRUNK UNLOCK). Check the harness between body integrated unit connector and trunk lid lock actuator connector. Connector & terminal (i171) No. 7 - (R186) No. 1: |
Is harness normal? | Go to step 6. | Repair or replace the harness. |
| 6 CHECK HARNESS (TRUNK UNLOCK). Measure the resistance between the trunk lid lock actuator connector and chassis ground. Connector & terminal (R186) No. 2 - Chassis ground: |
Is the resistance less than 10 Ω? | Go to step 7. | Repair or replace the harness. |
7 CHECK BODY INTEGRATED UNIT OUTPUT SIGNAL.
|
Does the voltage change from less than 1 V → 9 V or more? (During lock output) | Go to step 8. | Replace the body integrated unit. Refer to , BODY INTEGRATED UNIT . |
| 8 CHECK BODY INTEGRATED UNIT OUTPUT SIGNAL. Measure the voltage between the terminals of the body integrated unit connector when operating the door lock switch to UNLOCK direction. Connector & terminal Except for front door LH (i171) No. 3 (+) - (i171) No. 2 (-): Front door LH (i171) No. 4 (+) - (i171) No. 2 (-): |
Does the voltage change from less than 1 V → 9 V or more? (During unlock output) | Go to step 9. | Replace the body integrated unit. Refer to , BODY INTEGRATED UNIT . |
| 9 CHECK BODY INTEGRATED UNIT OUTPUT SIGNAL. Measure the voltage between body integrated unit connector and chassis ground when operating the rear gate/trunk opener button. Connector & terminal (i171) No. 7 (+) - Chassis ground (-): |
Does the voltage change from less than 1 V → 9 V or more? (During unlock output) | Go to step 10. | Replace the body integrated unit. Refer to , BODY INTEGRATED UNIT . |
| 10 CHECK DOOR LOCK ACTUATOR. Check the door lock actuator.
|
Is the door lock actuator OK? | OUTBACK model Go to step 11
. Sedan model: Go to step 12. |
Replace the door latch and door lock actuator assembly. |
| 11 CHECK REAR GATE LOCK ACTUATOR. Check the rear gate lock actuator. Refer to , REAR GATE LATCH AND ACTUATOR ASSEMBLY . |
Is the rear gate lock actuator normal? | Check the connection status of the harness and connector that may have a temporary poor contact. | Replace the rear gate latch and actuator assembly. |
| 12 CHECK TRUNK LID LOCK ACTUATOR. Check the trunk lid lock actuator. Refer to , TRUNK LID LATCH AND ACTUATOR ASSEMBLY . |
Is trunk lid lock actuator normal? | Check the connection status of the harness and connector that may have a temporary poor contact. | Replace the trunk lid latch & actuator assembly. |
