Service Cautions: Dynamometer

WARNING: This page is about a different car, the 2009 Mazda 6. 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 speed meter tester, pay attention to the following:
- 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.
- Since the rear bumper might deform from the heat, cool the rear with a fan. (Surface of the bumper must be below 70°C {158°F}.)
- Keep the area around the vehicle uncluttered so that heat does not build up.
- Watch the water temperature gauge and don't 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 ABS/TCS/DSC HU/CM determines that there is a malfunction in the ABS/TCS/DSC and illuminates the following lights:
- Vehicles with ABS/TCS
  - ABS warning light
  - Brake system warning light
  - TCS indicator light
- Vehicles with DSC
  - ABS warning light
  - Brake system warning light
  - DSC indicator light
If the above lights are illuminated, dismount the vehicle from the chassis dynamometer and turn the ignition switch to the LOCK position. Then, turn the ignition switch back to the ON position, run the vehicle at 10 km/h 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 [ABS]/[TCS]/[DSC] in the on-board diagnostic system.
