Vibration Method
- If malfunction occurs or becomes worse while driving on a rough road or when engine is vibrating, perform the steps below.
NOTE:
- There are several reasons vehicle or engine vibration could cause an electrical malfunction. Some of the things to inspect for are:
- Connectors not fully seated
- Wiring harnesses not having full play
- Wiring harnesses laying across brackets or moving parts
- Wiring harnesses routed too close to hot parts
- An improperly routed, improperly clamped, or loose wiring harness can cause wiring to become pinched between parts.
- The connector joints, points of vibration, and places where wiring harnesses pass through the fire wall, body panels, etc. are the major areas to be inspected.
