Road Test

ROAD TEST

NOTE: Warm up the engine to normal operating temperature (the radiator fan comes on).

1. Apply parking brake and block the wheels. Start the engine, then shift to [D4] position while depressing the brake pedal. Depress the accelerator pedal and release it suddenly. The engine should not stall.
2. Repeat same test in [D3] position.
3. Test drive the vehicle on the flat road in [D4] position. Check that the shift points occur at the approximate speeds. Also check for abnormal noise and clutch slippage.

NOTE: Throttle position sensor voltage represents the throttle opening.
- 1. Remove the PCM cover to expose the PCM for road testing.

- 2. Set the digital multimeter to check voltage between D6 (+) terminal and A26 (-) terminal of the PCM for the throttle position sensor.

NOTE: Refer to; How to use the Backprobe Set.

SRS components are located in this area. Review the SRS component locations, precautions, and procedures in the SRS section before performing repairs or service.





[D4]and [D3] Positions

NOTE:
- Lock-up ON: Lock-up control solenoid valve B turns on.
- Lock-up OFF: Lock-up control solenoid valve B turns off.

4. Accelerate to about 35 mph (57 km/h) so the transmission is in 4th, then shift from [D4] position to [2] position. The vehicle should immediately begin slowing down from engine braking.

CAUTION: Do not shift from [D4] or [D3] position to [2] or [1] position at speeds over 63 mph (100 km/h); you may damage the transmission.

5. Check for abnormal noise and clutch slippage in the following positions.
[1] (1st Gear) Position a. Accelerate from a stop at full throttle. Check that there is no abnormal noise or clutch slippage. b. Upshifts should not occur with the shift lever in this position.
[2] (2nd Gear) Position a. Accelerate from a stop at full throttle. Check that there is no abnormal noise or clutch slippage. b. Upshifts and downshifts should not occur with the shift lever in this position.
[R](Reverse) Position Accelerate from a stop at full throttle, and check for abnormal noise and clutch slippage.
6. Test in [P] (Parking) Position Park the vehicle on slope (approximately 16°) apply the parking brake, and shift into FP] position. Release the brake; the vehicle should not move.
