DIAGNOSIS AND REPAIR WORK FLOW
Use
TM-373, "Symptom Table" from the symptom inspection result in step 4. Then identify where to start per-
forming the diagnosis based on possible causes and symptoms.
>> GO TO 8.
7.REPAIR OR REPLACE THE MALFUNCTIONING PARTS
Repair or replace the detected malfunctioning parts.
Reconnect parts or connector after repairing or replacing, and then erase DTC if necessary.
>> GO TO 8.
8.FINAL CHECK
Perform “DTC CONFIRMATION PROCEDURE” again to make sure that the repair is correctly performed.
Check that malfunctions are not reproduced when obtaini ng the malfunction information from the customer,
referring to the symptom inspection result in step 3 or 4.
Is DTC or malfunction symptom reproduced?
YES-1 (DTC is reproduced.)>>GO TO 5.
YES-2 (Malfunction is reproduced.)>>GO TO 6.
NO >> Before delivering the vehicle to the customer, make sure that DTC is erased.
Diagnostic Work SheetINFOID:0000000009464226
DESCRIPTION
There are many operating conditions that may cause a malfunction
of the transmission parts. By understanding those conditions prop-
erly, a quick and exact diagnosis can be achieved.
In general, perception of a problem varies depending on individuals.
Ask the customer about his/her concer ns carefully. It is important to
understand the phenomenon or status. To systemize all the informa-
tion for the diagnosis, prepare the question sheet referring to the
question points.
In some cases, multiple conditions that appear simultaneously may
cause a DTC to be detected.

AdjustmentINFOID:0000000009464232
CAUTION:
• During adjustment of the CVT fluid level, check CO NSULT so that the oil temperature may be main-
tained from 35 to 45 °C (95 to 113 °F).
• During adjustment of the CVT fluid level, check that the engine speed is maintaining 500 rpm.
• Use caution when looking into the drain hole as th ere is a risk of dripping fluid entering the eye.
1. Check that the selector lever is in the “P ” position, then completely engage the parking brake.
2. Start the engine.
3. Adjust the CVT fluid temperature to be approximately 40 °C (104 °F).
NOTE:
The CVT fluid is largely affected by temperature. Therefore be sure to use CONSULT and check the
“FLUID TEMP” under “TRANSMISSION” in “Data Monitor” while adjusting.
4. While depressing the brake pedal, shift the selector lever to the entire position from “P” to “DS”, and shift it to the “P” position.
NOTE: CVT fluid : Refer to
TM-413, "General Specification"

CVT POSITION
InspectionINFOID:0000000009464234
1. Turn ON the ignition switch with the shift selector at the “P” position.
2. Press the shift selector button with the brake pedal depressed, and confirm that the shift selector can be
moved to positions other than “P”. Also confirm that movement is not allowed from the “P” position to other
position without depressing the brake pedal.
3. Move the shift selector and check for “excessive effort”, “sticking”, “noise” or “rattle”.
4. Confirm that shift selector stops at each position with the feel of engagement when it is moved through all
the positions. Check whether or not the actual position the shift selector is in matches the position shown
by the transaxle body.
5. Make sure that the shift selector is moved to all the shift posi- tions in the manner shown.
• (A): Press shift selector button to operate shift selector, while depressing the brake pedal.
• (B): Press shift selector button to operate shift selector.
• (C): Shift selector can be operated without pressing the shift selector button.
6. When the shift selector button is pressed without applying for- ward/backward force to the shift selector at “P”, “R”, “N”, “D” or
“Ds” positions, there should be no “sticking” on the shift selector
button operation.
7. Check that the back-up lamps do not illuminate when the shift selector is in the “P” position.
8. Check that the engine can be started with the sh ift selector in the “P” and “N” positions only.
9. Check that the transaxle is locked completely when the shift selector is in the “P” position.
AdjustmentINFOID:0000000009464235
1. Shift the shift selector to the “P” position.
CAUTION:
Turn wheels at least a quarter turn and be certain the park position mechanism is fully engaged.
2. Loosen the control cable nut. CAUTION:
Do not apply force to the manual lever.
3. Position the manual lever in the “P” position.
4. Tighten the control cable nut to specified torque. Refer to TM-
380, "Exploded View".
CAUTION:
Hold manual lever when tightening.
