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 COOLANT LEVEL INSPECTION [L8, LF].)

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

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

4.  Inspect the idle speed. (See ENGINE TUNE-UP [L8, LF].)

5.  Inspect the ignition timing. (See ENGINE TUNE-UP [L8, LF].)

6.  Verify that no DTCs are stored.

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].)

Note
•  Direct mode inspection is performed representatively between 3rd and 4th gears.

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

2.  Shift the selector lever to D range.

3.  Perform the following tests.

•  If there is any malfunction, inspect the steering shift switch. (See STEERING SHIFT SWITCH INSPECTION.)
(1)  When the vehicle is driven according to the following table, inspect the point at which the system switches from automatic shift mode to direct mode.

•  While driving under condition indicated on left and at constant speed for several seconds *, verify that system switches to automatic shift mode automatically.

*  :Depending on the driving conditions, the time required to switch to automatic shift mode may vary.


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].)
