D Range Test
1. Perform road test preparation.
2. Shift the selector lever to D range.
3. Accelerate the vehicle at half and WOT.
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.
^ If not as specified, inspect the PCM and ATX.
5. 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.
^ If not as specified, inspect the PCM and ATX.
6. Decelerate the vehicle and verify that engine braking effect is felt in 2GR, 3GR and 4GR.
^ If not as specified, inspect the PCM and ATX.
7. Drive the vehicle and verify that TCC operation is obtained. The operation points must be as shown in the table below.
^ If not as specified, inspect the PCM and ATX.
8. Select O/D OFF mode.
