ROAD TEST
DescriptionINFOID:0000000003806508
DESCRIPTION
 The purpose of the test is to determine the overall performance of
CVT and analyze causes of problems.
 The road test consists of the following three parts:
1. “Check Before Engine Is Started” TM-310
.
2. “Check at Idle” TM-311
.
3. “Cruise Test” TM-312
.
 Before the road test, familiarize yourself with all test procedures
and items to check.
 Perform tests for all the check items until a malfunction phenome-
non is detected. Perform diagnosis for NG items after the comple-
tion of road tests.
CONSULT-III SETTING PROCEDURE
 Using CONSULT-III, perform a cruise test and record the result.
 Print the result and ensure that shifts and lock-ups take place as per Shift Schedule.
1. Touch “Data Monitor” on “Direct Diagnostic Mode” screen.
2. Touch “MAIN SIGNALS” to set recording condition.
3. See “Numerical Display”, “Barchart Display” or “Line Graph Display”.
4. Touch “START”.
5. When performing cruise test. Refer to TM-312, "

INSPECTION
1. Place selector lever in “P” position, and turn ignition switch ON (engine stop).
2. Check that selector lever can be shifted to other than “P” position when brake pedal is depressed. Also
check that selector lever can be shifted from “P” position only when brake pedal is depressed.
3. Move the selector lever and check for excessive effort, sticking, noise or rattle.
4. Check that selector lever stops at each position with the feel of engagement when it is moved through all
the positions. Check that the actual position of the selector lever matches the position shown by the shift
position indicator and the manual lever on the transaxle.
5. The method of operating the selector lever to individual posi-
tions correctly should be as shown.
6. When selector button is pressed in “P”, “R”, “N”, “D” or “L” posi-
tion without applying forward/backward force to selector lever,
check button operation for sticking.
7. Check that back-up lamps illuminate only when selector lever is
placed in the “R” position.
8. When in “R” position, check that back-up lamps illuminate even
when the selector lever is pushed toward the “P” position.
CAUTION:
Check the lighting without pressing shift button.
9. Check that the back-up lamps do not illuminate when selector lever is pushed toward the “R” position
when in the “P” or “N” position.
CAUTION:
Check the lighting without pressing shift button.
10. Check that the engine can only be started with the selector lever in the “P” and “N” positions.
11. Check that transaxle is locked completely in “P” position.
ADJUSTMENT
1. Place selector lever in “ P” position.
CAUTION:
Turn wheels more than 1/4 rotations and apply the park lock.
2. Loosen nut (A) and place manual lever (B) in “P” position.
CAUTION:
Never apply any force to the manual lever.
3. Tighten nut. Refer to TM-319, "
Exploded View".
CAUTION:
