-
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 Idle Speed Inspection.)
5. Inspect the ignition timing. (See Ignition Timing Inspection.)
6. Wait until the engine and transmission reach 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 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].)
