ROAD TEST [SJ6A-EL]

id051311248900

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 ENGINE COVER REMOVAL/INSTALLATION [13B-MSP].)

2.  Inspect the engine oil level. (See ENGINE OIL LEVEL INSPECTION [13B-MSP].)

3.  Inspect the ATF level. (See AUTOMATIC TRANSMISSION FLUID (ATF) INSPECTION [SJ6A-EL].)

4.  Inspect the idle speed. (See ENGINE TUNE-UP [13B-MSP].)

5.  Inspect the ignition timing. (See ENGINE TUNE-UP [13B-MSP].)

6.  Verify that no DTCs are recorded.

D Range Test

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

2.  Shift the selector lever to the D range.

3.  Accelerate with the throttle half and then wide open.

4.  Verify that 1→2, 2→3, 3→4, 4→5, and 5→6 upshifts can be obtained. The shift points must be as shown in the table below.

•  If there is any malfunction, inspect the TCM and AT. (See SYMPTOM TROUBLESHOOTING ITEM TABLE [SJ6A-EL].)

5.  Drive the vehicle in 6GR, 5GR, 4GR, 3GR, 2GR and verify that kickdown occurs for 6→5, 5→4, 4→3, 3→2, and 2→1 downshifts, and that the shift points are as shown in the table below.

•  If there is any malfunction, inspect the TCM and AT. (See SYMPTOM TROUBLESHOOTING ITEM TABLE [SJ6A-EL].)

6.  Decelerate the vehicle and verify that engine braking effect is felt in 4GR, 5GR, and 6GR.

•  If there is any malfunction, inspect the TCM and AT. (See SYMPTOM TROUBLESHOOTING ITEM TABLE [SJ6A-EL].)

7.  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 TCM and AT. (See SYMPTOM TROUBLESHOOTING ITEM TABLE [SJ6A-EL].)

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, 4→5, and 5→6 upshifts and 6→5, 5→4, 4→3, 3→2, and 2→1 downshifts are obtained by manual shifting.

•  If there is any malfunction, inspect the TCM and AT. (See SYMPTOM TROUBLESHOOTING ITEM TABLE [SJ6A-EL].)

4.  Decelerate the vehicle and verify that 6→5, 5→4, 4→3, 3→2, and 2→1 downshifts are obtained. The shift points must be as shown in the table below.

•  If there is any malfunction, inspect the TCM and AT. (See SYMPTOM TROUBLESHOOTING ITEM TABLE [SJ6A-EL].)

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

•  If there is any malfunction, inspect the TCM and AT. (See SYMPTOM TROUBLESHOOTING ITEM TABLE [SJ6A-EL].)

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

•  If there is any malfunction, inspect the TCM and AT. (See SYMPTOM TROUBLESHOOTING ITEM TABLE [SJ6A-EL].)
