Diagnostic Trouble Code for Data Link
CDL Code Description Information About the Code
248-9 Cat Data Link not communicating The engine ECM cannot communicate with the electronic service tool.
There are no 168 diagnostic codes.
The following background information is related to this procedure:The data link is the standard data link that is used by the ECM to communicate with the electronic service tool.The ECM provides multiple connections for the data link. The technician must ensure that the correct connector is being tested. The connection that is used depends on the application.If the diagnostic connector is off the engine, the positive data link signal will be from P1:48 to pin "G" of the diagnostic connector. The negative data link signal will be from P1:59 to pin "F" of the diagnostic connector.If the diagnostic connector is on the engine, the positive data link signal will be from pin number 20 on the ECM Adapter to pin "G" of the diagnostic connector. The negative data link signal will be from pin number 21 on the ECM Adapter to pin "G" of the diagnostic connector.The following information refers to the pin number. Ensure that the correct connector is used.CommunicationThe electronic service tool may indicate 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is not guaranteed.This message will indicate that the version of the software that is in the electronic service tool is obsolete. Install the latest version of the software for the electronic service tool to rectify the fault.

Troubleshooting Test Steps Values Results
1. Inspect Electrical Connectors and Wiring
A. Turn the keyswitch to the OFF position.
B. Inspect the connectors in the circuit for the data link.
Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
E. Check all of the wiring associated with the data link for corrosion, abrasion and pinch points from the ECM to the Diagnostic Connector.
Note: Do not disconnect the ECM connector at this stage. The ECM can only be disconnected and reconnected 10 times before damage to the harness connector may occur.
Damaged wire or connector
Result: A damaged wire or damaged connector was found.
Repair: Repair the damaged wire or the damaged connector.
Use the electronic service tool to clear all logged diagnostic codes. Verify that the repair eliminates the fault.
Result: A damaged wire or damaged connector was not found.
Proceed to Test Step 2.
2. Determine the Type of Fault in the Data Link
A. Connect the electronic service tool to the diagnostic connector that is on the engine harness or on the application.
B. Turn the keyswitch to the ON position.
Power to the comms adapter
Result: The power lamp illuminates on the communications adapter. The communications adapter is currently receiving the correct voltage.
Proceed to Test Step 4.
Result: The power lamp is not illuminated on the communications adapter. The communications adapter is not currently receiving the correct voltage.
Proceed to Test Step 3.
3. Check the Battery Voltage at the Diagnostic Connector
A. Turn the keyswitch to the ON position.
B. Use a multimeter to measure the voltage from pin A (battery+) and pin B (ground) of the diagnostic connector.
11.0 VDC and 13.5 VDC for a 12 VDC system. 22.0 VDC and 27.0 VDC for a 24 VDC system.
Result: The voltage is between 22.0 VDC and 27.0 VDC for a 24 V system. The voltage is between 11.0 VDC and 13.5 VDC for a 12 V system. The diagnostic connector is currently receiving the correct voltage.
Proceed to Test Step 4.
Result: The voltage is not between 22.0 VDC and 27.0 VDC for a 24 V system. The voltage is not between 11.0 VDC and 13.5 VDC for a 12 V system. The diagnostic connector is not currently receiving the correct voltage.
Repair: The fault is in the wiring harness. Repair the faulty harness or replace the faulty harness.
Proceed to Test Step 4.

Troubleshooting Test Steps Values Results
4. Check the Data Link Connections
A. Turn the keyswitch to the OFF position.
B. Disconnect the communications adapter from the diagnostic connector.
C. If the diagnostic connector is installed on the engine, disconnect the ECM Adapter connector. Check the resistance between pin 21 and pin "F" on the diagnostic connector. Check the resistance between pin 20 and pin "G" on the diagnostic connector.
D. Reconnect the ECM Adapter connector. Check the resistance between P1:59 and pin "F" on the diagnostic connector. Check the resistance between P1:48 and pin "G" on the diagnostic connector.
E. If the diagnostic connector is installed on the application, dis
