Note: Warm up the engine to operating temperature (radiator fan is 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 accelerator pedal and release it sharply. The engine should not stall.
2. Repeat the same test in [D3] position.
3. Test drive 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: The throttle position sensor voltage indicates the throttle opening.
- 1. Remove ECM (S4PA), TCM (S4XA)
- 2. S4PA
Set up a digital multitester to check the voltage between D1 (+) terminal and A9 or A22 (-) terminal of the throttle position sensor.
S4XA
Set up a digital multitester to check the voltage between terminal 64 (+) and terminal A13 or A26 (-) for the throttle position sensor.

4. Accelerate to approximately 57 km / h with the transmission in 4th gear, then switch from [D4J position to [2] position. The vehicle must immediately start slowing down due to engine braking.
Attention. Do not switch from [D4] or [03] position a [2] or [1] position at speeds over 100 km / h: you may damage the transmission.
5. Check for abnormal noise and clutch slippage in the following positions.
[1] (1st gear) Position (7-position transmission)
- 1. Accelerate from a standstill with the throttle fully open. Check for abnormal noise or clutch slippage.
- 2. Upper and lower shifting should not occur in this position.
[2] (2nd gear) position
- 1. Accelerate from a standstill with the throttle fully open. Check for abnormal noise or clutch slippage.
[R] (reverse) Position
Accelerate from a standstill with the throttle open and check for abnormal noise and clutch slippage.
6. Test in [R] (Parking) Position
Place the car on a slope (approximately 16°), set the parking brake, and shift to the [P] position. Release the brake, the car should not move.
