Road Test
ROAD TEST [JA5A-EL]Road Test Preparation
1. Inspect the engine coolant.
2. Inspect the engine oil.
3. Inspect the ATF levels.
4. Inspect the idle speed and ignition timing in P position.
5. Bring up the engine and transaxle to normal operating temperature.
Typical Shift Diagram
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 approximately 5% or more, and shifts to NORMAL mode when the upgrade is approximately 3% or less.
1. Perform 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.
^ If not as specified, inspect the TCM and ATX.
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.
^ If not as specified, inspect the TCM and ATX.
5. Decelerate the vehicle and verify that engine braking effect is felt in 5GR.
^ If not as specified, inspect the TCM and ATX.
6. Drive the vehicle and verify that TCC operation is obtained. The operation points must be as shown.
^ If not as specified, inspect the TCM and ATX.
Note: The shift solenoid electrical ON-OFF pattern in this chart describes the stabilized condition before and after shift control. The pattern may oscillate between ON and OFF momentarily while shifting-up or down. This is normal.

M Range Test
1. Perform road test preparation.
2. Shift the selector lever to M range.
3. Verify that 1-2, 2-3, 3-4, and 4-5 upshifts and 5-4, 4-3, 3-2, and 2-1 downshifts are obtained by manual shifting of the selector lever forward and back. The shift points must be as shown.
^ If not as specified, inspect the TCM and ATX.
4. Decelerate the vehicle and verify that 5-4, 4-3, 3-1, and 2-1 downshifts are obtained. The shift points must be as shown.
^ If not as specified, inspect the TCM and ATX.
5. Decelerate the vehicle and verify that engine braking effect is felt in all gears.
^ If not as specified, inspect the TCM and ATX.
6. Drive the vehicle and verify that TCC operation is obtained in 5GR. The operation points must be as shown.
^ If not as specified, inspect the TCM and ATX.

Noise and Vibration Test
1. Drive the vehicle and listen closely for any noise or vibration. The torque converter, drive shaft, and differential can be sources of noise and vibration if they are not functioning properly. Inspect these when searching for sources of noise and vibration.
P Position Test
1. Shift into P position on a gentle slope. Release the brake, and verify that the vehicle does not roll.
^ If the vehicle rolls, inspect the ATX.
