STEP 4. Measure the resistance at combination meter 
connector D-03.
(1) Disconnect connector D-03 and measure at the harness 

side.

(2) Measure the resistance between terminal 57 and ground.

• The measured resistance should be less than 2 ohms.

Q: Is the measured resistance less than 2 ohms?

YES : Go to Step 7.
NO :  Go to Step 5.

STEP 5. Check combination meter connector D-03 and 
joint connector D-30 for loose, corroded or damaged 
terminals, or terminals pushed back in the connector.
Q: Are the connectors and terminals in good condition?

YES : Go to Step 6.
NO :  Repair or replace the damaged components. Refer to
