id051703802200

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 COOLING SYSTEM SERVICE WARNINGS[L3].) (See ENGINE COOLANT LEVEL INSPECTION[L3].)

2.  Inspect the engine oil level. (See ENGINE OIL LEVEL INSPECTION[L3].)

3.  Inspect the ATF level. (See AUTOMATIC TRANSAXLE FLUID (ATF) INSPECTION[GF4AX-EL].)

4.  Inspect the ignition timing. (See ENGINE TUNE-UP[L3].)

5.  Inspect the idle speed. (See ENGINE TUNE-UP[L3].)

6.  Bring up the engine and transaxle to normal operating temperature.

D Range Test

1.  Perform road test preparation. (See Road Test Preparation.)

2.  Shift the selector lever to D range.

3.  Accelerate the vehicle at half and wide open.

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. (O/D OFF switch off)

•  If there is any malfunction, inspect the PCM and ATX. (See SYMPTOM TROUBLESHOOTING ITEM TABLE[GF4AX-EL].)

5.  Verify that 1→2 and 2→3 upshifts and downshifts are obtained. (O/D OFF switch ON)

•  If there is any malfunction, inspect the PCM and ATX. (See SYMPTOM TROUBLESHOOTING ITEM TABLE[GF4AX-EL].)

6.  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. (O/D OFF switch off)

•  If there is any malfunction, inspect the PCM and ATX. (See SYMPTOM TROUBLESHOOTING ITEM TABLE[GF4AX-EL].)

7.  Drive the vehicle in 3GR and 2GR and verify that kickdown occurs for 3→2, 3→1 downshifts. (O/D OFF switch ON)

•  If there is any malfunction, inspect the PCM and ATX. (See SYMPTOM TROUBLESHOOTING ITEM TABLE[GF4AX-EL].)

8.  Decelerate the vehicle and verify that engine braking effect is felt in 1GR and 2GR.

•  If there is any malfunction, inspect the PCM and ATX. (See SYMPTOM TROUBLESHOOTING ITEM TABLE[GF4AX-EL].)

9.  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 PCM and ATX. (See SYMPTOM TROUBLESHOOTING ITEM TABLE[GF4AX-EL].)

2 Range Test

1.  Perform road test preparation. (See Road Test Preparation.)

2.  Verify that 2GR is held.

•  If there is any malfunction, inspect the PCM and ATX. (See SYMPTOM TROUBLESHOOTING ITEM TABLE[GF4AX-EL].)

3.  Decelerate the vehicle and verify that engine braking effect is felt.

•  If there is any malfunction, inspect the PCM and ATX. (See SYMPTOM TROUBLESHOOTING ITEM TABLE[GF4AX-EL].)


1 Range Test

1.  Perform road test preparation. (See Road Test Preparation.)

2.  Verify that 1GR is held.

•  If there is any malfunction, inspect the PCM and ATX. (See SYMPTOM TROUBLESHOOTING ITEM TABLE[GF4AX-EL].)

3.  Decelerate the vehicle and verify that engine braking effect is felt.

•  If there is any malfunction, inspect the PCM and ATX. (See SYMPTOM TROUBLESHOOTING ITEM TABLE[GF4AX-EL].)


P Position Test

1.  Shift into P position on a gentle slope. Release the brake and verify that the vehicle does not roll.

•  If there is any malfunction, inspect the ATX. (See SYMPTOM TROUBLESHOOTING ITEM TABLE[GF4AX-EL].)
