Monitors, Trips, Drive Cycles and Readiness Codes
Road TestNOTE: Warm up the engine to normal operating temperature (the radiator fan comes on).
1. Apply the parking brake and block the wheels. Start the engine, then shift to [04] 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 a flat road in the [D4] position. Check that the shift points occur at the approximate speeds shown. Also check for abnormal noise and clutch slippage.
NOTE: Throttle position sensor voltage represents the throttle opening.
a. Unbolt the PCM for road testing.
b. Set the digital multimeter to check voltage between C27 (+) terminal and B20 (-) or B22 (-) terminal of the PCM for the throttle position sensor.
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.
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 [D3] or [D3] position to [2] position at speeds over 63 mph 1100 km/h); you may damage the transmission.
5. Check for abnormal noise and clutch slippage in the following positions.
[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 selector 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 (approx. 16 degrees), apply the parking brake, and shift into [P] position. Release the brake; the vehicle should not move.
