AFFECTED VEHICLES

Year Model Trim
2019 MDX Sport Hybrid ALL
2019 RDX ALL
2019 TLX ALL V6

BACKGROUND

Some troubleshooting procedures for a loss of communication or F-CAN malfunction DTC’s require running the F-CAN Bus Connected Unit Check using the i-HDS. There are certain control units that may be reported as Not Available in the Status column even though they are properly communicating.

 

F-CAN Bus Connected Unit Check

This bulletin illustrates two scenarios that may be a concern, and how to proceed with troubleshooting in each case. Keep in mind that what you see can vary depending on the vehicle, the DTC, or the symptom being addressed.

 

PROCEDURE

Scenario 1: U0100/U0122 Troubleshooting: Affected control units reading Not Available are not needed for your troubleshooting.

Scenario 1: U0100/U0122 Troubleshooting

In this scenario, EPS CONTROL UNIT and GAUGE CONTROL MODULE read Not Available when the unit check is finished. These two units are not needed to complete PCM and VSA modulator-control unit troubleshooting, and the PCM and VSA modulator-control unit report as Detected normal at this time. Troubleshooting is finished at this point since there is no longer a communication failure.

EPS CONTROL UNIT and GAUGE CONTROL MODULE read Not Available

 

Scenario 2: U0131 Troubleshooting: The affected control units reported as Not Available are needed for your troubleshooting.

Scenario 2: U0131 Troubleshooting

In this scenario, communication with a control unit that is reporting as Not Available can be confirmed by selecting the applicable system from the System Selection Menu in the i-HDS. If the system is available and communicating, it will be highlighted. In this case, EPS and Body Electrical are available. If the system is not communicating, it will be grayed out as shown.

From here you can select either system and confirm the communication.

select either system and confirm the communication

Once confirmed, keep following the service information troubleshooting. If the system is available and communicating, select Detected normal. If it is grayed out or not communicating, select the applicable Not Available response.
