Road Test
Road TestNOTE: Warm up the engine to normal operating temperature (the radiator fan comes on).
1. Before testing, check the transmission fluid level.
2. Apply the parking brake and block the wheels. Start the engine, then shift to D4 position while pressing the brake pedal. Press the accelerator pedal and release it suddenly. The engine should not stall.
3. Repeat same test in D4 position.
4. Test-drive the vehicle on a flat road in the D4 position. Check that the shift points occur at approximate speeds shown on a flat road. Also check for abnormal noise and clutch slippage.
Throttle position sensor voltage represents the throttle opening. Monitor it with the Honda PGM Tester or as follows:
a. Unbolt the PCM for road testing.
b. Set the digital multimeter to check throttle position sensor voltage between C27 (+) terminal and B20 (-) or B22 (-) terminal on the PCM.
D4 Position:
Upshift
Downshift
NOTE:
- Lock-up ON: The lock-up control solenoid valve A turns ON.
- Lock-up OFF: The lock-up control solenoid valve A turns OFF.
5. 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.
6. Check for abnormal noise and clutch slippage in the following positions.
(1) (1st Gear) Position Accelerate from a stop at full throttle. Make sure there is no abnormal noise or clutch slippage. Upshifts should not occur with the shift lever in this position.
(2) (2nd Gear) Position Accelerate from a stop at full throttle. Make sure there is no abnormal noise or clutch slippage. 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.
7. Test in P (Park) Position
Park the vehicle on slope (approximately 16°). apply the parking brake, and shift into [P] position. Release the brake; the vehicle should not move.
