Vibration Method

• If a malfunction occurs or becomes worse while driving on a rough road or when the engine is vibrating,

perform following the steps:

Note

• There are several reasons why vehicle or engine vibration could cause an electrical malfunction. Some of

the things to inspect for:

— Connectors not fully seated.

— Wiring 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 wiring harness can cause wiring to become pinched

between parts.

• The connector joints, points of vibration, and places where wiring harnesses pass through the firewall,

body panels are the major areas to be inspected.
