| Step | Check | Yes | No |
|---|---|---|---|
| 1 CHECK DOOR LOCK SWITCH. Check that the lock/unlock operates with the driver's door lock switch. |
Does it lock/unlock normally? | Go to step 2 . | Check the door lock circuit. < Refer to SYMPTOM CHART , INSPECTION, Door Lock Control System. > |
| 2 CHECK FUSE. Check the fuse. |
Is the fuse OK? | Go to step 3 . | Replace the fuse. |
3 CHECK HARNESS.
|
Is the resistance less than 1 Ω? | Go to step 4 . | Repair or replace the open circuit of harness. |
| 4 CHECK HARNESS. Using a tester, measure the resistance between the keyless access CM connector and chassis ground, and between oscillator connector and chassis ground. Connector & terminal (i242) No. 12 - Chassis ground: (D65) No. 10 - Chassis ground: (i242) No. 13 - Chassis ground: (D65) No. 5 - Chassis ground: |
Is the resistance 10 kΩ or more? | Go to step 5 . | Repair or replace the short circuit of the harness. |
5 CHECK KEYLESS ACCESS CM.
|
Does pulse output change from pulse output OFF → pulse output ON by the lock operation using access key? | Go to step 6 . | Replace the keyless access CM. < Refer to KEYLESS ACCESS CM . > |
| 6 REPLACE FRONT DOOR OUTER HANDLE. Replace the driver's side front outer handle with the passenger's side front outer handle. |
Does it operate properly? | Replace the driver's front outer handle. < Refer to FRONT OUTER HANDLE . > | Replace the keyless access CM. < Refer to KEYLESS ACCESS CM . > |
