Vibration method

WARNING: This page is about a different car, the 2004 Mazda RX-8. However, it is still accessible from the selected car via links, so may be relevant.

If a malfunction occurs or becomes worse while driving on a rough road or when the engine is vibrating, perform the following steps.

NOTE:

There are several reasons why vehicle or engine vibration could cause an electrical malfunction. Inspect the following:
- 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 harness can cause wiring to become pinched between parts.
The connector joints, point of vibration, and places where wiring harnesses pass through the firewall, body panels and other panels are the major areas to be inspected.
