Road Test
- Warm engine to normal operating temperature. Apply parking brake and block wheels. Start engine. Move shift lever to "D4" while depressing brake pedal. Depress accelerator pedal and release it suddenly. Engine should not stall.
- Repeat step 1
in "D3". Ensure engine does not stall. Ensure ignition is off. Remove door sill molding on passenger's side and remove small cover on right kick panel. Pull carpet back for access to PGM-FI Electronic Control Unit (ECU). This is the ECU for the fuel injection system.
- Remove bracket from above ECU. Install Test Harness (07LAJ-PT3010A) between PGM-FI ECU and connector. The PGM-FI ECU is located on passenger's side, below carpet. See Fig 1
.
NOTE:
Test harness is installed so throttle angle sensor voltage can be monitored while performing road test.

- Install Digital Volt-Ohmmeter (DVOM) on test harness with positive lead at terminal D11 and negative lead at terminal D22. Terminal numbers are on top of test harness. See Fig 1
. Ensure digital volt-ohmmeter is set for measuring voltage.
- Road test vehicle and check for abnormal noise and clutch slippage. Specified clutch is applied in designated gears. See CLUTCH APPLICATION
table.
- Note that shift points are within specification in accordance with throttle angle sensor voltage reading or throttle position with shift lever in "D4" position. See TRANSAXLE UPSHIFT SPECIFICATIONS (MPH)
and TRANSAXLE DOWNSHIFT SPECIFICATIONS (MPH)
tables.
- With shift lever in "D4" position, accelerate to about 35 MPH so transaxle is in 4th gear. Move shift lever to "2" position, and ensure engine braking occurs.
CAUTION:
DO NOT shift from "D4" or "D" to "2" or "1" at speeds over 62.5 MPH or transaxle may be damaged.
- 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 range.
- 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 range.
- Place shift lever in "R" position. Accelerate from a stop at full throttle. Check for abnormal noise or clutch slippage.
- Park vehicle on a slope. Apply parking brake and place shift lever in "P" position. Release parking brake and ensure vehicle does not move. If vehicle moves, check for defective shift cable or parking components.
- Shut engine off. Remove test harness and reconnect PGM-FI ECU electrical connectors.
