ROAD TEST [SJ6A-EL]

WARNING:

NOTE:

Road Test Preparation

1. Inspect the engine coolant level. (See ENGINE COOLANT LEVEL INSPECTION [LF].)
2. Inspect the engine oil level. (See ENGINE OIL LEVEL INSPECTION [LF].)
3. Inspect the ATF level. (See AUTOMATIC TRANSMISSION FLUID (ATF) LEVEL ADJUSTMENT [SJ6A-EL].)
4. Inspect the idle speed. (See ENGINE TUNE-UP[LF].)
5. Inspect the ignition timing. (See ENGINE TUNE-UP[LF].)
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.
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.
6. Decelerate the vehicle and verify that engine braking effect is felt in 4GR, 5GR, and 6GR.
7. Drive the vehicle and verify that TCC operation is obtained. The operation points must be as shown in the table below.
