If the connector is corroded or dirty, clean it carefully. If it is damaged, replace it.

Use the wiring diagram to find the ends of the lead which is suspected of being a problem.
Connect the hand tester between the ends of the leads.
Special Tool - Hand Tester: 57001-1394
Set the tester to the × 1 Ω range, and read the tester.
If the tester does not read 0 Ω, the lead is defective. Replace the lead or the wiring harness [A] if necessary.
