Emergency Engine Stop Operation

WARNING: This page is about a different car, the 2020 Mazda CX-30. However, it is still accessible from the selected car via links, so may be relevant.

While performing an inspection by rotating the wheels using a dynamometer, if the ABS HU/CM (with ABS system) or DSC HU/CM (with DSC system) detects a vehicle speed signal error, the engine cannot be stopped using the push button start. If the engine cannot be stopped using the push button start, perform an emergency stop using the following procedure.
1. Continuously pressing the push button start or quickly pressing it any number of times while the engine is running or the vehicle is being driven will turn the engine off immediately. The ignition switches to ACC.
Cautions on Chassis Dynamometer Use
When inspecting and servicing the powertrain on the dynamometer or speedometer tester, pay attention to the following:
NOTE:
- If the engine cannot be stopped using the push button start, perform an emergency engine stop operation. (See Cautionss for vehicles with Mazda Radar Cruise Control (MRCC) system/Mazda Radar Cruise Control with stop & go function (MRCC with stop & go function) system/Traffic Jam Assist (TJA)/Smart Brake Support (SBS) system/Smart Brake Support [Rear] (SBS-R) system/Smart Brake Support [Rear Crossing] (SBS-RC) system/Distance & Speed Alert (DSA)/Lane-keep assist system.)
  - Place a fan, preferably a vehicle-speed proportional type, in front of the vehicle.
  - Make sure the vehicle is in a facility with an exhaust gas ventilation system.
  - Keep the rear bumper cool by placing a cooling fan near the exhaust pipe so that the rear bumper does not get deformed by the heat from the exhaust.
  - Keep the area around the vehicle uncluttered so that heat does not build up.
  - Watch the water temperature gauge and do not overheat the engine.
  - Avoid added load to the engine and maintain normal driving conditions as much as possible.
