Slippage Tests

SLIPPAGE TEST
This step is performed to inspect for slippage of the friction elements.

Preparation
1. Perform the preparation procedure:

- Check the engine coolant, engine oil, and ATF levels before testing.
- Warm the engine thoroughly to raise the ATF temperature to operating level (60-70 °C, 140-158°F)

2. Connect a tachometer to the engine and set it in the cabin.
3. Connect the EC-AT Tester between the EC-AT control unit and wire harness.

Procedure





Drive the vehicle in each of the gears indicated below and verify that the vehicle speed or engine speed is within specification as indicated by the drum speed.

Evaluation
When there is no malfunction in the electrical system or hydraulic system, but the vehicle speed is too low or the engine speed is too high, the problem can be attributed to slippage of the friction elements.
