APPENDIX A (Section 6)
TR690 CVT Diagnosis Assistance Application
This application can assist in diagnosing various concerns, including but not limited to lock-up
judder, lock-up engagement shock, input clutch slip, chain slip, and forward clutch judder. However,
it does not have the capability to diagnose transfer clutch, noise, DTC related, or engine performance
concerns.
Key Information for Successful Testing:
•

The test drive should be performed with the ATF oil temperature above 50̊ F. Driving without
warming up the CVT fluid will result in incorrect results.

•

Using the Subaru Select Monitor (SSM), check- and record ALL TCM data PIDs.
 Note: You must use the select monitor data monitor. Data collected using the “Gear Ratio
Change Rate Error Judgement” will not work with the application.

•

The data file must be longer than 1 min but cannot exceed 30 mins. If more than 30 minutes is
required to duplicate the concern, please begin a new data file recording.

WARNING: Do not use the application to verify repairs. The application is not a repair
verification tool and use of the application should be strictly limited to the initial diagnostic
process. Because of the application’s high sensitivity, using it after repairs have been completed
may produce inaccurate or misleading results. If the concern cannot be reproduced after
repairs, the repair is considered successful. If the customer concern persists after performing the
repair recommended by the diagnostic assistance application, Techline must be contacted before
moving forward with any additional parts replacement.
Step 1) Convert Project File to CSV After Recording SSM TCM Data
From the Project file:
•

APPENDIX B:
(INFORMATIONAL PURPOSES ONLY)
CVT Chain Slip Diagnosis Procedure:
There are three main forms of CVT chain slip.
1. Continuous Micro-Slip
2. Short-Time Slip
3. Long-Time Slip
Using Subaru Select Monitor (SSM), check and record data monitors and compare to the three
examples listed below. If the recorded data from the vehicle matches the examples below, the CVT
will require replacement. The SSM data will be required for claim submission. A QMR containing the
same information will also be required.
1. Continuous Micro-Slip

Examples of the data monitoring during Continuous Micro-Slip:

2.

Short-Time Slip

When a short-time slip occurs, the changes in the Actual Gear Ratio monitor will be larger than 0.1
per 0.1 second. After the Actual Gear Ratio monitor resumes to stable conditions, distinct fluctuations
in revolution speed continues.
Example Graph of Short Time Slip:

3.

Long-Time Slip

When a long-time slip occurs, the Primary UP Duty monitor will be larger than 90% and the Actual
Pulley Ratio monitor lowers for a duration of 0.5 seconds or more. Even after the Actual Gear Ratio
monitor resumes to stable conditions, distinct fluctuations in revolution speed continues.

REFERENCE MATERIAL:
Symptoms Similar to CVT Chain Slip:
1. Forward Clutch Slip Shock
This shock can occur when the forward clutch slips. If this situation is reported, reprogram the TCM
with the newest software available.
The rotation speeds for the upstream and downstream sides of the forward clutch do not synchronize
when driving.
Example for
2.4L Turbo or 3.6L NA equipped vehicles
Upstream side of the forward clutchSecondary Rev Speed
Downstream side of the forward clutchFront Wheel Speed
