Warning
• When performing a road test, be aware of other vehicles, people, impediments to avoid an accident.
Note
• When the legal speed limit must be exceeded, use a chassis dynamometer instead of performing a road test.

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 level. (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.

D range (normal mode)

D Range Test

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

2. Shift the selector lever to D range.

3. Accelerate the vehicle at half and wide open.

4. Verify that 1→2, 2→3, and 3→4 upshifts and downshifts are obtained. The shift points must be as shown in the table below. (O/D OFF switch off)

• If there is any malfunction, inspect the PCM and ATX. (See SYMPTOM TROUBLESHOOTING ITEM TABLE [GF4AX-EL].)

5. Verify that 1→2 and 2→3 upshifts and downshifts are obtained. (O/D OFF switch ON)

• If there is any malfunction, inspect the PCM and ATX. (See SYMPTOM TROUBLESHOOTING ITEM TABLE [GF4AX-EL].)

6. Drive the vehicle in 4GR, 3GR, and 2GR and verify that kickdown occurs for 4→3, 3→2, 2→1 downshifts, and that the shift points are as shown in the table below. (O/D OFF switch off)

• If there is any malfunction, inspect the PCM and ATX. (See SYMPTOM TROUBLESHOOTING ITEM TABLE [GF4AX-EL].)

7. Drive the vehicle in 3GR and 2GR and verify that kickdown occurs for 3→2, 3→1 downshifts. (O/D OFF switch ON)

• If there is any malfunction, inspect the PCM and ATX. (See SYMPTOM TROUBLESHOOTING ITEM TABLE [GF4AX-EL].)

8. Decelerate the vehicle and verify that engine braking effect is felt in 1GR and 2GR.

• If there is any malfunction, inspect the PCM and ATX. (See SYMPTOM TROUBLESHOOTING ITEM TABLE [GF4AX-EL].)

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

• If there is any malfunction, inspect the PCM and ATX. (See SYMPTOM TROUBLESHOOTING ITEM TABLE [GF4AX-EL].)

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

2. Verify that 2GR is held.

• If there is any malfunction, inspect the PCM and ATX. (See SYMPTOM TROUBLESHOOTING ITEM TABLE [GF4AX-EL].)

3. Decelerate the vehicle and verify that engine braking effect is felt.

• If there is any malfunction, inspect the PCM and ATX. (See SYMPTOM TROUBLESHOOTING ITEM TABLE [GF4AX-EL].)

1 Range Test

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

2. Verify that 1GR is held.

• If there is any malfunction, inspect the PCM and ATX. (See SYMPTOM TROUBLESHOOTING ITEM TABLE [GF4AX-EL].)

3. Decelerate the vehicle and verify that engine braking effect is felt.

• If there is any malfunction, inspect the PCM and ATX. (See SYMPTOM TROUBLESHOOTING ITEM TABLE [GF4AX-EL].)

P Position Test

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