The following twenty two “22” Diagnostic Trouble Codes will display in transmission controller window, will be stored in memory and the “Check Diagnostic Trouble Code” light on the display monitor will be ON: F311, F314, F321, F324, F330, F331, F334, F335, F340, F341, F344, F345, F3A0, F3A5, F3C0, F3C5, F3D0, F3D5, F3E0, F3E5, F3H1, F3H4. There are sixty two “62” Diagnostic Trouble Codes.

The failure must be fixed before calibrating again. If the fourth digit of the diagnostic trouble code number is (6, 7, 8, or 9), it is the result of calibrating indicating there is a failure. If diagnostic trouble code (311, 314, 321, or 324) is displayed DO NOT CALIBRATE, see diagnostic trouble codes. Compare calibrated values to real time values! If values don't match RECALIBRATE.

Access main menu and select DIAG in transmission controller. If the fourth digit of the diagnostic trouble code number is (1 or 4), a calibration error or circuit failure is indicated. If the fourth digit of the diagnostic trouble code number is (0, 2, 3, or 5), a open circuit, shorted circuit, or no feed back is indicated. If the third digit of the diagnostic trouble code number is (T), it indicates a problem with B4 Transmission Speed In Grip (SIG). If the third digit of the diagnostic trouble code number is (R), it indicates a problem with B27 Reverse Speed Ratio switch. If the third digit of the diagnostic trouble code number is (L), it indicates a problem with Y4 (LH) Motor Shift Solenoid. If the third digit of the diagnostic trouble code number is (K), it indicates a problem with Y3 (RH) Motor Shift Solenoid. Wrong transmission controller, or when a new transmission controller has been installed and not calibrated. If the third digit of the diagnostic trouble code number is (J), it indicates the F3J4 diagnostic trouble code was displayed when exiting calibration with out completion. If the third digit of the diagnostic trouble code number is (H), it indicates a problem with S3 Neutral Start Switch. If the third digit of the diagnostic trouble code number is (P), it indicates a problem with S20 Park Lock Lever Switch and/or S4 Brake Pedal Switch. If the third digit of the diagnostic trouble code number is (C or D), it indicates a problem with B9 Front (RH) Pump Pressure Control Pilot (PCP).

If the third digit of the diagnostic trouble code number is (A or E), it indicates a problem with B8 Rear (LH) Pump Pressure Control Pilot (PCP). If the third digit of the diagnostic trouble code number is (9), it indicates a problem with B6 Hydrostatic Pump Speed Sensor. If the third digit of the diagnostic trouble code number is (8 or N), it indicates a problem with B3 Right Track Motor Speed Sensor. If the third digit of the diagnostic trouble code number is (7 or M), it indicates a problem with B7 Left Track Motor Speed Sensor. If the third digit of the diagnostic trouble code number is (6), it indicates a problem with B4 Transmission Speed Control Sensor. If the third digit of the diagnostic trouble code number is (5), it indicates a problem with B1 Decelerator Sensor. If the third digit of the diagnostic trouble code number is (4), it indicates a problem with B5 Left and Right Steer Sensor. If the third digit of the diagnostic trouble code number is (3), it indicates a problem with B2 FNR Sensor. If the third digit of the diagnostic trouble code number is (2), it indicates that battery voltage is less than 9 volts or more than 16.5 volts. If the third digit of the diagnostic trouble code number is (1), it indicates that at least one of the sensor voltage wires is less than 4.75 volts or more than 5.25 volts. The last two digits of diagnostic trouble code number indicate specific failures. The number 3 means the transmission controller has diagnosed a problem in the transmission area and has sent a diagnostic trouble code to the controller window to be displayed. The letter F means that a fault has occurred.

The diagnostic trouble code number is indicated by an F3 plus two other digits. Investigate circuit failure identified by diagnostic trouble code.

When diagnostic trouble code appears, shut engine off and restart engine to check if diagnostic trouble code is an intermittent problem. Transmission controller diagnostic trouble codes will display when malfunction occurs.
