Road Test

NOTE: If shift lever cannot be moved from "P" position with brake pedal depressed and accelerator pedal at idle position, check shift interlock system. See ACURA/HONDA SHIFT INTERLOCK SYSTEMS article.
  1. Warm engine to normal operating temperature. Apply parking brake and block wheels. Start engine. Move shift lever to "D4" position while depressing brake pedal. Depress accelerator pedal and release it suddenly. Engine should not stall.
  2. With shift lever in "D" position, repeat step  1. Ensure engine does not stall.
    3. NOTE: Manufacturer recommends monitoring Throttle Position (TP) sensor voltage when performing road test to ensure proper throttle opening for verifying shift points and torque converter lock-up.
  3. Ensure ignition is off. Remove door sill molding and lower dash panel on passenger's side and remove small cover on passenger's side kick panel. Pull carpet back for access to PCM. Remove PCM cover.
  4. Install Backprobe Test Set (07SAZ-001000A) or equivalent between PCM harness connector and DVOM leads. See Fig 1. Set DVOM to measure voltage. Connect DVOM positive lead to PCM harness connector terminal D6 and negative lead to terminal A26. See Fig 1.

  5. Road test vehicle and check for abnormal noise and clutch slippage. See CLUTCH APPLICATION  under TROUBLE SHOOTING for clutch engagement.
  6. Ensure upshift and downshift points and torque converter lock-up are correct in relation to throttle position sensor voltage or throttle opening and vehicle speed with shift lever in "D4" position. See TRANSAXLE UPSHIFT SPECIFICATIONS  and TRANSAXLE DOWNSHIFT SPECIFICATIONS  tables.
    7. CAUTION: DO NOT shift from "D4" to "2" at speeds over 62 MPH or transaxle may be damaged.
  7. With shift lever in "D4" position, accelerate to about 35 MPH so transaxle is in 4th gear. Move shift lever to "2" position. Ensure engine braking occurs.
  8. Place shift lever in "1" position. Accelerate from a stop at full throttle. Check for abnormal noise or clutch slippage. Upshifts and downshifts should not occur in this shift lever position.
  9. Place shift lever in "2" position. Accelerate from a stop at full throttle. Check for abnormal noise or clutch slippage. Upshifts and downshifts should not occur in this shift lever position.
  10. Place shift lever in "R" position. Accelerate from a stop at full throttle. Check for abnormal noise or clutch slippage.
  11. Park vehicle on a slope. Apply parking brake. Place shift lever in "P" position. Release parking brake. Ensure vehicle does not move. If vehicle moves, check for defective shift cable or parking components.
  12. Ensure ignition is off. Remove test harness and reinstall electrical connectors, PCM cover, carpet and door sill molding.
