Foreword
This manual is written for an experienced technician. Essential tools required in performing certain service work are identi ed in this manual and are recommended for use.
Live with safety: Read the safety messages in the introduction of this manual and the cautions presented throughout the text of the manual.
CAUTION:
This is the safety-alert symbol. When you see this symbol on the machine or in this manual, be alert to the potential for personal injury.
Technical manuals are divided in two parts: repair and operation and tests. Repair sections tell how to repair the components. Operation and tests sections help you identify the majority of routine failures quickly.
Information is organized in groups for the various components requiring service instruction. At the beginning of each group are summary listings of all applicable essential tools, service equipment and tools, other materials needed to do the job, service parts kits, speci cations, wear tolerances, and torque values.
Technical Manuals are concise guides for speci c machines. They are on-the-job guides containing only the vital information needed for diagnosis, analysis, testing, and repair.
Fundamental service information is available from other sources covering basic theory of operation, fundamentals of troubleshooting, general maintenance, and basic type of failures and their causes.

( 2 ) Verify Code
Action:
Recall, record and clear codes.
NOTE:
If using SERVICE ADVISOR , this procedure can be performed by making a connection to the CCD bus and using the Diagnostic tab to view and clear codes. If connected through SERVICE ADVISOR, DO NOT use manual procedure for accessing codes.
If not connected to the tractor through SERVICE ADVISOR, see Reference 245-05-001 for procedure.
Recall codes again and check for return of this code.
Result:
YES:Code does not return. GO TO (3) .
NO:Code returns. GO TO (4)
( 3 ) Operational Check
Action: NOTE:
Remove diagnostic fuse from F10 location before performing the following operational check.
Hydro Fixed Unit Speed Sensor (B41)
APC Controller (A101)
Circuit 609
Circuit 050
NOTE:
See APC Wiring Diagram in Reference 240-35-100 (Wiring Diagram Listing), for test points.
Result:

APC 119- Carrier Speed Low at Start-Up
03
The APC giving full outboard command to the hydro control solenoid, and the carrier speed input to the APC does not come within 250 rpm of the internally calculated expected carrier speed within 25 seconds of startup.

( 1 ) Preliminary Check
Action:
AccessAPC Address 38 .
Display should read: 38 048
NOTE:
The value stored at APC Address 38 is the con guration for the pulses or gear teeth that pass the carrier speed sensor in one revolution. An incorrect value stored at this address will prohibit correct speed calculation.
Check to ensure that the Transmission Enable fuse from the F37 location is not installed at the F41 location.
Result:
YES: GO TO (2) .
NO:Display does not read 048 . Change and save as necessary. (See APC Calibration 245-APC-001 for procedure). GO TO (2) .

FABRICATION: Modify JDG774 Tap-Out Harness as shown (to be able to read current draw) by doing the following.
Measure 104 mm (4 in) (A) from one end of the Weather Pack connector (F) along the wire attached to terminal A . Mark and cut the wire.
Strip insulation approximately 5 mm (3/16 in) from each end of cut wire.
Add a R65597 blade terminal and R77475 female connector body (B) to one end.
Add a U46662 female terminal and M43835 male connector body (C) to the other end.
USE: DFRW126 is used to measure the current draw (in mA), of the power shift transmission analog shift valve solenoids, at di erent steps of valve engagement. Current draw data is used to analyze performance of the electronic portion of the shift valve.
Connect the ammeter in series by attaching meter leads to disconnected male and female terminals (B and C).
NOTE:
Terminals (B and C) must be connected when using the tap-out harness as JDG774 for making voltage readings.
