Note: Warm up the engine to operating temperature (radiator fan on).
1. Apply the parking brake and block the front wheels. Start the engine, then shift to position [D4] while pressing the brake pedal. Press the gas pedal and release it quickly. The engine should not stall.
2. Repeat the same test in [D3] position.
3. Test the vehicle on a level road in the [D4] position. Check that shifts occur at the approximate speeds shown. Also check for abnormal noise and clutch slippage.
Note: Throttle position sensor voltage indicates throttle opening.
- 1. Remove the ECM (S4PA), TSM (S4XA)
- 2. S4PA
Install a digital multitester to check the voltage between D1 (+) contact and A9 or A22 (-) throttle position sensor contact.
S4XA
Install a digital multitester to check the voltage between 64 (+) contact and A13 or A26 (-) contact for the throttle position sensor.

4. Accelerate to approximately 57 km/h with the transmission in 4th, then shift from [D4J position to [2] position. The car should immediately begin to slow down due to engine braking.
Attention. Do not shift from [D4] or [03] position to [2] or [1] position at speeds above 100 km/h: you may damage the transmission.
5. Check for abnormal noise and slippage of the clutches in the following positions.
[1] (1st gear) Position (7-position transmission)
- 1. Accelerate from a standstill with the throttle wide open. Check for abnormal noise or clutch slippage.
- 2. Up and down shifts should not occur in this position.
[2] (2nd gear) position
- 1. Accelerate from a stop with the throttle wide open. Check for abnormal noise or clutch slippage.
[R] (reverse) Position
Accelerate from a stop with the throttle slightly open and check for abnormal noise and clutch slippage.
6. Test in [P] (Parking) Position
Place the car on an incline (approximately 16°), apply the parking brake, and switch to the [P] position. Release the brake; the car should not move.
