Symptom Troubleshooting [Dynamic Stability Control System]: NVH Mazda 3 BL рестайлинг

Vibration method

1. 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 are: 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.

Scheme 67

1. Connect the M-MDS to DLC-2.
2. Switch the ignition to ON (engine off). NOTE: If engine starts and runs, perform the following steps at idle.
3. Access the PIDs for the switch you are inspecting.
4. Turn switch on manually.
5. Shake each connector or wire harness a bit vertically and horizontally while monitoring the PID. (Scheme 67): Shaking Connector Or Wire Harness Vertically If the PID value is unstable, check for poor connection.

Scheme 68

1. Connect the M-MDS to DLC-2.
2. Switch the ignition to ON (engine off). NOTE: If engine starts and runs, perform the following steps at idle.
3. Access the PIDs for the switch you are inspecting.
4. Shake each connector or wire harness a bit vertically and horizontally while monitoring the PID. (Scheme 68): Shaking Connector Or Wire Harness Horizontally If the PID value is unstable, check for poor connection.
