  • Malfunction of door lock control system
  • Door lock switch circuit malfunction
  • Malfunction of harness between keyless access control module and front door outer handle
  • Keyless access control module malfunction
  • Malfunction of front door outer handle
CAUTION:
  • Check that there are no other registered access keys inside the vehicle. 
  • 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 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. 
  • Before performing diagnosis, refer to "CAUTION" in "General Description". Ref. to  KEYLESS ACCESS WITH PUSH BUTTON START (DIAGNOSTICS)>GENERAL DESCRIPTION>CAUTION  . 
  1. CHECK DOOR LOCK SWITCH  .

    Check that the lock/unlock operates with the driver's door lock switch.

      (i241) No. 6 - (D66) No. 6:

      (i241) No. 5 - (D66) No. 4:

    Is the resistance less than 1 Ω?

    Yes:  Go to  5.

    No:  Repair or replace the open circuit of harness.

  5. CHECK HARNESS (GROUND SHORT CIRCUIT)  .

    Using a tester, measure the resistance between the keyless access control module connector and chassis ground.

    Connector & terminal 

    (i241) No. 6 - Chassis ground:

    (i241) No. 5 - Chassis ground:

    Is the resistance 10 kΩ or more?
