How it works:
The PCM compares actual driving conditions with memorized driving conditions, based on the input from the vehicle speed
sensor, the throttle position sensor, the barometric pressure sensor ('98 model). the engine coolant temperature sensor, the
brake switch signal, and the shift lever position signal, to control shifting while the vehicle is ascending or descending a
slope, or reducing speed.

Road Test
NOTE: Warm up the engine to normal operating temperature (the radiator tan comes on).
1. Before testing, check the transmission fluid level, see page 14-160.
2. Apply the parking brake and block the wheels. start the engine, then shift to E {'97 - 98) or E {'gg - 00) position
while pressing the brake pedal. Press the accelerator pedal and release it suddenly. The engine should not stall.
3. Repeat same test in E position ('97 - 98 models).
4. Test-drive the vehicle on a flat road in the E or E 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; reJer to page 14-58.
b. Set the digital multimeter to check throttle position sensor voltage between these terminals on the PCM:
. '97 Model: Between terminals D'! (+) and A9 (-) or A22 {-}
. '98 - OO Models; Between terminals C27 (+) and 820 (-) or 822 {-)

Upshift
NOTE:
. Lock-upON:The lock-up control solenoid valve A turns ON.. Lock-up OFF: The lock-up control solenoid valve A turns OFF.
4. Accelerate to about 35 mph (57 km/h) so the transmission is in 4th. then shift from E or E position to E position.The vehicle should immediately begin slowing down from engine braking.
5. Check for abnormal noise and clutch slippage in the following positions.
E {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.
E (2nd cear) Position
Accelerate from a stop at fuI throttre. Make sure there is no abnormar noise or crutch srippage.Upshifts and downshifts should not occur with the shift lever in this position.
E (Reverse) Position
Accelerate from a stop at full throttle. and check for abnormal noise and clutch slippage.
6. Test in E (Park) Position
Park the vehicle on slope (approx. 16"), apply the parking brake, and shift into E position. Release the brake; the vehi-cle should not move.
