Mazda 6 Service Manual: Intermittent concern troubleshooting
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.
