Cautions On Chassis Dynamometer Use
- When inspecting and servicing the power train on the dynamometer or speedometer 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.
- 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 CLEARING DTC [DYNAMIC STABILITY CONTROL (DSC)] .)
- If the engine cannot be stopped using the push button start, perform an emergency engine stop operation. (See EMERGENCY ENGINE STOP OPERATION .)
