ROAD TEST [JA5AX-EL]

id051705802200

## Road Test Preparation

1. Inspect the engine coolant. (See ENGINE COOLANT LEVEL INSPECTION [L8, LF, L3, L3 Turbo].)

2. Inspect the engine oil. (See ENGINE OIL LEVEL INSPECTION [L8, LF, L3].)

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

4. Inspect the idle speed and ignition timing in P position. (See Idle Speed Inspection.) (See Ignition Timing Inspection.)

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

D range (normal mode)

## D Range 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. Perform road test preparation. (See Road Test Preparation.)

2. Shift the selector lever to D range.

3. Accelerate the vehicle with half and WOT, then verify that 1→ 2, 2→ 3, 3→ 4, and 4→ 5 upshifts and downshifts are obtained. The shift points must be as shown in the table below.

  • If not as specified, inspect the TCM and ATX. (See AUTOMATIC TRANSAXLE SYMPTOM TROUBLESHOOTING [JA5AX-EL].)

4. Drive the vehicle in 5GR, 4GR, 3GR, and 2GR and verify that kickdown occurs for 5→4, 4→3, 3→2, and 2→1 downshifts, and that the shift points are as shown in the table below.

  • If not as specified, inspect the TCM and ATX. (See AUTOMATIC TRANSAXLE SYMPTOM TROUBLESHOOTING [JA5AX-EL].)

5. Decelerate the vehicle and verify that engine braking effect is felt in 5GR.

  • If not as specified, inspect the TCM and ATX. (See AUTOMATIC TRANSAXLE SYMPTOM TROUBLESHOOTING [JA5AX-EL].)

6. Drive the vehicle and verify that TCC operation is obtained. The operation points must be as shown in the table below.

  • If not as specified, inspect the TCM and ATX. (See AUTOMATIC TRANSAXLE SYMPTOM TROUBLESHOOTING [JA5AX-EL].)

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.

## M Range Test

1. Perform road test preparation. (See Road Test Preparation.)

2. Shift the selector lever to M range.

3. Verify that 1→ 2, 2→ 3, 3→ 4, and 4→ 5 upshifts and 5→ 4, 4→ 3, 3→ 2, and 2→ 1 downshifts are obtained by manual shifting of the selector lever forward and back. The shift points must be as shown in the table below.

  • If not as specified, inspect the TCM and ATX. (See AUTOMATIC TRANSAXLE SYMPTOM TROUBLESHOOTING [JA5AX-EL].)

4. Decelerate the vehicle and verify that 5→ 4, 4→ 3, 3→ 1, and 2→ 1 downshifts are obtained. The shift points must be as shown in the table below.

  • If not as specified, inspect the TCM and ATX. (See AUTOMATIC TRANSAXLE SYMPTOM TROUBLESHOOTING [JA5AX-EL].)

5. Decelerate the vehicle and verify that engine braking effect is felt in all gears.

  • If not as specified, inspect the TCM and ATX. (See AUTOMATIC TRANSAXLE SYMPTOM TROUBLESHOOTING [JA5AX-EL].)

6. Drive the vehicle and verify that TCC operation is obtained in 5GR. The operation points must be as shown in the table below.

  • If not as specified, inspect the TCM and ATX. (See AUTOMATIC TRANSAXLE SYMPTOM TROUBLESHOOTING [JA5AX-EL].)

M3→M 1 | 4-10 {3-6} | 200-400

## 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 the vehicle rolls, inspect the ATX. (See AUTOMATIC TRANSAXLE SYMPTOM TROUBLESHOOTING [JA5AX-EL].)
