Initial Inspection and Diagnostic Overview
Road TestSpecial Tools Required
Backprobe set 07SAZ-001000A (Two required)
1. Warm up the engine to normal operating temperature (the radiator fan comes on).
2. Apply the parking brake, and block both rear wheels. Start the engine, then shift to the [D] position while pressing the brake pedal. Press the accelerator pedal, and release it suddenly. The engine should not stall.
3. Repeat step 2 in the [D] position.
4. Connect the Honda PGM Tester (A) to the DLC (B), and go to the PGM-FI Data List; then go to step 7. If you don't have a PGM Tester, go to step 5.
5. Pull back the carpet, and remove the driver's and passenger's console side trims.
6. Connect a digital multimeter (A) and the special tools (B) to check voltage between PCM connector terminals C27 (+) and B20 (-) or B22 (-).
7. Test-drive the vehicle on a flat road in the [D] position. Check for abnormal noise and clutch slippage. While driving, check that the shift points occur at the proper speeds by monitoring the throttle position sensor voltage and comparing your shift point speeds and voltage to those in the table. (The throttle position sensor voltage represents the throttle opening.)
8. Accelerate to about 35 mph (57 km/h) so the transmission is in 4th or 5th, then shift from the [D] position to the [2] position. The vehicle should immediately begin slowing down from engine braking.
9. Check for abnormal noise and clutch slippage in the following positions.
[1] (1st Gear) Position
Accelerate from a stop at full throttle. Check that 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. Check that 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.
10. Test in [P] (Park) Position. Park the vehicle on a slope (about 15°), apply the brake, and shift into the [P] position. Release the brake; the vehicle should not move.
