Service Cautions: Dynamometer
- 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/DSC HU/CM determines that there is a malfunction in the ABS and illuminates the following lights:
- Vehicles with ABS
- ABS warning light
- Brake system warning light
- Vehicles with DSC
- ABS warning light
- Brake system warning light
- DSC indicator light
- Vehicles with ABS
- If the above lights are illuminated, dismount the vehicle from the chassis dynamometer and switch the ignition to LOCK. Then, switch the ignition to 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]/[DSC] in the on-board diagnostic system. (See ON-BOARD DIAGNOSIS [ABS] .)(See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)] .)
