Go to Step 3.

Repair the defective connector.

STEP 3. Resistance measurement at the C-111 and C-113 combination meter connector.


(1)Disconnect the connector, and measure at the wiring harness side.

(2)Resistance between C-111 combination meter connector terminal No.57 and body earth
OK: Continuity exists (2 Ω or less)

(3)Check the resistance between the C-113 combination meter connector terminal No.13 and body earth.
OK: Continuity exists (2 Ω or less)

Q. Is the check result normal?

Go to Step 5.

Go to Step 4.

STEP 4. Check the wiring harness from C-111 combination meter connector terminal No.57 or C-113 combination meter connector terminal No.13 to body earth.
