DLK-70 < DTC/CIRCUIT DIAGNOSIS > [WITH INTELLIGENT KEY SYSTEM] BACK DOOR LOCK ACTUATOR RELAY BACK DOOR LOCK ACTUATOR RELAY Description INFOID:0000000009950506 Controls back door lock actuator lock/unlock operation. Component Function Check INFOID:0000000009950507 1. CHECK FUNCTION 1. Use CONSULT to perform Active Test (“DOOR LOCK”). 2. Touch “ALL LOCK” or “ALL UNLK” to check that it works normally. Is the inspection result normal? YES >> Back door lock actuator relay is OK. NO >> Refer to DLK-68, "BACK DOOR : Diagnosis Procedure" Diagnosis Procedure INFOID:0000000009950508 1. CHECK FUSE 1. Turn ignition switch OFF. 2. Check 10 A fuse, [No. 10, located in fuse block (J/B)]. Is the inspection result normal? YES >> GO TO 2. NO >> Replace the blown fuse after repairing the affected circuit if a fuse is blown. 2. CHECK BACK DOOR LOCK ACTUATOR RELAY POWER CIRCUIT 1. Remove back door lock actuator relay. 2. Check voltage between back door lock actuator relay harness connector and ground. Is the inspection result normal? YES >> GO TO 3. NO >> Repair or replace harness. 3. CHECK BACK DOOR LOCK ACTUATOR RELAY CIRCUIT 1 1. Install the back door lock relay. 2. Check voltage between BCM harness connector and ground. Is the inspection result normal? YES >> GO TO 6. NO-1 (when voltage is fixed at 12V)>>Replace BCM. Refer to BCS-88, "Removal and Installation" NO-2 (when voltage is fixed at 0V)>>GO TO 4. 4. CHECK BACK DOOR LOCK ACTUATOR RELAY CIRCUIT 1 1. Disconnect BCM connector. 2. Check voltage between BCM harness connector and ground. (+) (–) Voltage (V) (Approx.)
