## 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 why vehicle or engine vibration could cause an electrical malfunction. Some of the things to check for:

  – Connectors not fully seated.
  – Wire harnesses not having full play.
  – Wires laying across brackets or moving parts.
  – Wires routed too close to hot parts.

  • An improperly routed, improperly clamped, or loose harness can cause wiring to become pinched between parts.
  • The connector joints, points of vibration, and places where wire harnesses pass through the firewall, body panels, etc. are the major areas to be checked.
  • Check for DTCs or malfunctions by shaking harnesses and connectors that are suspected to be causing malfunction.

## Connector Terminal Check Method

1. Check the connection condition of each female terminal.

2. Insert male terminal into the female terminals to check for looseness.
