Initial Inspection and Diagnostic Overview

Test

Special 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 rear wheels. Start the engine, then shift to D4 position while pressing the brake pedal. While fully pressing the brake pedal press the accelerator pedal, and release it suddenly. The engine should not stall.
3. Repeat the same test in D3 position.





4. Connect the Honda PGM Tester (A), 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 from the passenger's side of the center console to expose the PCM (A).





6. Connect the digital multimeter (B) and the special tools (C) to check voltage between the C27 (+) terminal and B20 (-) or B22 (-) terminal of the PCM.
7. Test-drive the vehicle on a flat road in the D4 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.)





Upshift-D4 position





Downshift-D4 position

8. 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.
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 that there is no abnormal noise or clutch slippage.
10. Test in P (Park) Position.
Park the vehicle on a slope (approximately 16°), apply the parking brake, and shift into P position. Release the brake; the vehicle should not move.
