(1) Disconnect joint connector (CAN1), and check that there is

continuity at the harness side of joint connector (CAN1).

(2) Check that there is continuity between joint connector

(CAN1) terminals 10 and 23.

OK: No continuity

Q: Is the check result normal?

YES (vehicles without satellite radio) : Go to Step 33.
YES (vehicles with satellite radio) : Go to Step 32.
NO : Go to Step 50.

STEP 31. Check the wiring harness between joint
connector (CAN1) C-103 and CAN box unit connector C-13
for line-to-line short. Measure the resistance at joint
connector (CAN1) C-103.
(1) Disconnect joint connector (CAN1), and check that there is

continuity at the harness side of joint connector (CAN1).

(2) Check that there is continuity between joint connector

(CAN1) terminals 10 and 23.

OK: No continuity

Q: Is the check result normal?

YES (vehicles without satellite radio) : Go to Step 33.
YES (vehicles with satellite radio) : Go to Step 32.
NO : Go to Step 51.

STEP 32. Check the wiring harness between joint
connector (CAN1) C-103 and satellite radio tuner
connector C-111 for line-to-line short. Measure the
resistance at joint connector (CAN1) C-103.
(1) Disconnect joint connector (CAN1), and check that there is

continuity at the harness side of joint connector (CAN1).
