CDL Code Code Description Comments
246-9 Proprietary CAN Data Link : Abnormal Update Rate The Electronic Control Module (ECM) has lost communications over the CAN data link.
The code is logged.
The check engine lamp is illuminated.
247-9 SAE J1939 Data Link : Abnormal Update Rate The ECM has lost all communications over the global CAN data link.
The code is logged.
The check engine lamp is illuminated.
248-9 Cat Data Link not communicating The ECM has lost all communications with the transmission over the Cat Data Link.
The code is logged.
The check engine lamp is illuminated.
296-9 Transmission Control : Abnormal Update Rate The ECM has lost all communications with the transmission.
The code is logged.
The check engine lamp is illuminated.
533-9 Brake Control : Abnormal Update Rate The ECM has lost all communications with brake control.
The code is logged.
The check engine lamp is illuminated.
1273-9 Chassis Control Module : Abnormal Update Rate The ECM has lost all communications with the chassis control module over the Cat Data Link.
The code is logged.
The check engine lamp is illuminated.
1639-2 Machine Security System Module : Erratic, Intermittent, or Incorrect The ECM has lost communications with the Machine Security System Module (MSSM) over the Cat Data Link.
The code is logged.
The check engine lamp is illuminated.
1639-9 Machine Security System Module : Abnormal Update Rate The ECM has lost all communications with the Cat Monitoring System over the Cat Data Link.
The code is logged.
The check engine lamp is illuminated. Note: If a 1639-2 diagnostic code is active, verify that the following information is correct before proceeding with this procedure:
The part number of the flash software for the Machine ECM
The part number of the flash software for the Machine Security System ECM
The part number of the Machine ECM
The part number of the Machine Security System ECMIf the Caterpillar Electronic Technician (ET) will not communicate with the ECM, refer to Troubleshooting, "Electronic Service Tool Does Not Communicate" before you begin this procedure. The procedure verifies that electrical power is being supplied to the ECM and to the service tool connector.The data links are used to communicate information between the engine ECM and other control modules that are a part of the application. Cat ET also communicates with the ECM via the data links.The service tool connector contains connections for electrical power and for the data links.When the keyswitch is in the OFF position, Cat ET may communicate with the ECM. However, the communications may be disrupted and the communications may require frequent reconnection. In order to avoid this problem, place the keyswitch in the ON position when Cat ET is being used.Cat ET may display the following error message:"The version of the ECM is not recognized and the integrity of the changed parameters and displayed data is not guaranteed."This message indicates that one of the following conditions exist:
The flash file in the ECM is newer than the version of Cat ET.
The latest version of Cat ET has not been installed.

Troubleshooting Test Steps Values Results
1. Verify the Proper Installation of the Data Link Circuit
A. Disconnect the P1 ECM connector.
B. Measure the resistance between P1-50 and P1-34.
Data Link Circuit
Result: The resistance is between 57 ohms and 63 ohms and a -9 code is logged.
Repair: Check the power supply and ground to the module and all ECMs on the Can Data Link and the Cat Data Link that pertain to the -9 code that is logged or active. Power loss to any control module will generate a -9 code. Refer to the electrical schematic for details.
STOP
Result: The resistance is between 114 ohms and 126 ohms. A terminating resistor is missing.
Repair: Verify that two terminating resistors exist on the data link. One resistor must be located on each end of the data link. The engine is shipped with one terminating resistor that is installed between the ECM and the customer connector. Refer to the electrical schematic to determine the missing resistor. Replace the missing resistor and verify that the repair eliminates the problem.
STOP
Result: The resistance is less than 57 ohms.
Proceed to Test Step 2.
Result: The resistance is greater than 126 ohms.
Proceed to Test Step 3.

Troubleshooting Test Steps Values Results
2. Check for a Short Circuit
A. Turn the keyswitch to the OFF position.
B. Thoroughly inspect the connectors that are associated with the data link circuits. Refer to Troubleshooting, "Electrical Connectors - Inspect".
C. Disconnect the P1 ECM connector.
D. Disconnect Cat ET from the service tool connector.
E. Remove the terminating resistors from the CAN Data Link circuit.
F. Disconnect the J1939 display if equipped.
G. Measure the resistance between the points that are listed in Table 4. Be sure to wiggle the wires in
