Symptom Troubleshooting [Dynamic Stability Control System]: NVH Mazda MX-5 NC рестайлинг

Vibration method

1. 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. 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 wiring harnesses pass through the firewall, body and other panels are the major areas to be inspected.

1. Connect the M-MDS to the DLC-2.
2. Turn the ignition switch to the ON position (Engine off). NOTE: If the engine starts and runs, perform the following steps at idle.
3. Access PIDs for the switch you are inspecting.
4. Turn the switch on manually.
5. Slightly shake each connector or wiring harness vertically and horizontally while monitoring the PID. If the PID value is unstable, inspect for poor connection.
