2013 Mazda MX-5 Miata Grand Touring, Automatic TransFACTORY OEM SERVICE PROCEDURE

Vibration Method

  • If malfunction occurs or becomes worse while driving on a rough road or when the engine is vibrating, perform the steps below.
NOTE:
  • There are several reasons vehicle or engine vibration could cause an electrical malfunction. Inspect the following:
    • Connectors not fully seated
    • Wiring harnesses not having full play
    • Wiring harnesses laying across brackets or moving parts
    • Wiring harnesses 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 such as through the firewall and body panels are the major areas to be checked.
