D Range Test
Note
• The NORMAL mode and SLOPE mode are automatically selected by the TCM in D range. The TCM shifts
to SLOPE mode when the upgrade is approx. 5 % or more, and shifts to NORMAL mode when the
upgrade is approx. 3 % or less.
1. Perform road test preparation. (See K2–75 Road Test Preparation.)
2. Shift the selector lever to D range.
3. Accelerate the vehicle with half and WOT, then verify that 1→2, 2→3, 3→4, and 4→5 upshifts and downshifts
are obtained. The shift points must be as shown in the table below.
• If not as specified, inspect the TCM and ATX. (See K2–183 AUTOMATIC TRANSAXLE SYMPTOM
TROUBLESHOOTING.)
4. Drive the vehicle in 5GR, 4GR, 3GR, and 2GR and verify that kickdown occurs for 5→4, 4→3, 3→2, and 2→1
downshifts, and that the shift points are as shown in the table below.
• If not as specified, inspect the TCM and ATX. (See K2–183 AUTOMATIC TRANSAXLE SYMPTOM
TROUBLESHOOTING.)
5. Decelerate the vehicle and verify that engine braking effect is felt in 5GR.
• If not as specified, inspect the TCM and ATX. (See K2–183 AUTOMATIC TRANSAXLE SYMPTOM
TROUBLESHOOTING.)
6. 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 TCM and ATX. (See K2–183 AUTOMATIC TRANSAXLE SYMPTOM
TROUBLESHOOTING.)
