Initial Inspection and Diagnostic Overview
TestSpecial Tools Required
Backprobe set 07SAZ-001000A (2 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. Connect the Honda PGM Tester (A) to the DLC (B), and go to the PGM-FI Data List; then go to step 9. If you don't have a PGM Tester, go to step 4.
4. Remove the glove box stops, then open the glove box.
5. Remove the harness connector clamp (A) from its bracket.
6. Loosen the mounting nut (B) on the lower right of the PCM, and remove the mounting bolt (C) and nut (D) on the left of the PCM.
7. Lift the PCM up to clear the mounting nut on the lower right of the PCM, then pull out the PCM (E).
8. Connect a digital multimeter (A) and the special tools (B) to check voltage between PCM connector terminals A15 (+) and A23 (-) or A24 (-).
9. 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.)

10. Accelerate to about 35 mph (57 km/h) so the transmission is in 4th gear, then shift to 2nd gear. The vehicle should immediately begin slowing down from engine braking.
11. Accelerate from a stop at full throttle in the 1 position. Check that there is no abnormal noise or slippage. Upshifts should not occur with the shift lever in this position.
12. Accelerate from a stop at full throttle in the HI position. Check that there is no abnormal noise or slippage. Upshifts and downshifts should not occur with the shift lever in this position.
13. Accelerate from a stop at full throttle in the R position. Check that there is no abnormal noise or slippage.
14. Test in P (Parking) Position.
Park the vehicle on a slope (about 16°), apply the parking brake, and shift into the P position. Release the brake; the vehicle should not move.
