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 degrees. )
- 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 wheels are being rotated on the dynamometer, the ABS warning light could illuminate. If the ABS warning light illuminates, turn the ignition switch to the LOCK position, then turn it back to the ON position, run the vehicle at 10km/h and check that the ABS warning light goes off. (In this case, a DTC will be stored in the memory. To delete this data from the memory, follow the procedure for deleting DTCs (ABS) from memory.) (See ON-BOARD DIAGNOSTIC (ABS) article.)
