ROAD TEST [JA5A-EL]

BME051701030205

## Road Test Preparation

1. Inspect the engine coolant level. (See COOLING SYSTEM SERVICE WARNINGS.) (See ENGINE COOLANT LEVEL INSPECTION.)

2. Inspect the engine oil level. (See ENGINE OIL LEVEL INSPECTION.)

3. Inspect the ATF levels. (See Automatic Transaxle Fluid (ATF) Level Inspection.)

4. Inspect the ignition timing. (See Ignition Timing Inspection.)

5. Inspect the idle speed. (See Idle Speed Inspection.)

6. Bring up the engine and transaxle to normal operating temperature.

## Shift Schedule Test

  Note

  • The NORMAL mode and SLOPE mode are automatically selected by the TCM in D range. The TCM shifts to SLOPE mode when the upgrade is approx. 5 % or more, and shifts to NORMAL mode when the upgrade is approx. 3 % or less.

1. Drive the vehicle with wide open throttle, closed throttle position and kickdown, and verify that following shifts are obtained. The shift points must be as shown in the table below.

  • 1GR→2GR, 2GR→3GR, 3GR→4GR, and 4GR→ 5GR upshifts and downshifts are obtained in D range (HOLD switch OFF).
  • 2GR→3GR, 3GR→ 4GR upshifts and 5GR→4GR, 4GR→3GR, 3GR→2GR downshifts are obtained in D range (HOLD switch ON).
  • 1GR→2GR, 2GR→3GR, 3GR→4GR upshifts and 5GR→4GR, 4GR→3GR, 3GR→2GR and 2GR→1GR downshifts are obtained in S range (HOLD switch OFF).
  • 2GR→3GR upshifts and 5GR→4GR, 4GR→3GR, 3GR→2GR downshifts are obtained in S range (HOLD switch ON).
  • 1GR→2GR, 2GR→3GR upshifts and 5GR→4GR, 4GR→3GR, 3GR→2GR and 2GR→1GR downshifts are obtained in L range (HOLD switch OFF).
  • 5GR→4GR, 4GR→3GR, 3GR→2GR downshifts are obtained in L range (HOLD switch ON).

2. Decelerate the vehicle under the following conditions, and verify the engine braking effect base on the turbine and engine speeds.

  • 5GR in D, S, L range.
  • 4GR in D range (HOLD switch ON), S, L range.
  • 3GR in S range (HOLD switch ON), L range.
  • 2GR in L range (HOLD switch ON).

3. Drive the vehicle and verify that TCC operation is obtained in 4GR and 5GR in D range (HOLD switch OFF) and 4GR in S range (HOLD switch OFF).

  Note

  • The shift solenoid electrical ON-OFF pattern is this chart describes the stabilized condition before and after shift control. The pattern may oscillate between ON and OFF momentarily while shifting-up or down. This is normal.

## Noise and Vibration Test

1. Drive the vehicle and listen closely for any noise or vibration. The torque converter, drive shaft, and differential can be sources of noise and vibration if they are not functioning properly. Inspect these when searching for sources of noise and vibration.

## P Position Test

1. Shift into P position on a gentle slope. Release the brake, and verify that the vehicle does not roll.

  • If there is any malfunction, inspect the ATX. (See SYMPTOM TROUBLESHOOTING ITEM TABLE [JA5A-EL].)
