Cautions on chassis dynamometer use

WARNING: This page is about a different car, the 2017 Mazda 3. However, it is still accessible from the selected car via links, so may be relevant.

When inspecting and servicing the power train 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 EMERGENCY ENGINE STOP OPERATION .)

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.

NOTE:

When only the front or rear wheels are rotated on a chassis dynamometer or equivalent, the DSC HU/CM determines that there is a malfunction in the DSC and illuminates the following lights:
- ABS warning light
- Brake system warning light
- TCS/DSC indicator light
If the above lights are illuminated, dismount the vehicle from the chassis dynamometer and switch the ignition off. Then, switch the ignition ON (engine on), run the vehicle at 10 km/h {6.2 mph} or more and verify that the warning lights go out. In this case, a DTC will be stored in the memory. Clear the DTC from the memory by following the memory clearing procedure [DSC] in the on-board diagnostic system. (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)] .)
