Troubleshooting CAN Circuit Related Problems

WARNING: This page is about a different car, the 2011 Honda Insight and 2010 Honda Insight. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Check the PCM for DTCs and troubleshoot PCM (see GENERAL TROUBLESHOOTING INFORMATION ) or F-CAN loss of communication errors first.

Using the HDS (Preferred method)

Connect the HDS to the Data Link Connector (DLC).

NOTE: There are two ways to read B-CAN code with the HDS.

First method: Go to B-CAN System Diagnosis Test Mode A to check for DTCs (see TROUBLESHOOTING - B-CAN SYSTEM DIAGNOSIS TEST MODE A ).

Second method: Ground the SCS circuit with the HDS, then read the DTCs displayed in the multi-information display (MID) in the gauge assembly, then go to B-CAN System Diagnosis Test Mode A (see TROUBLESHOOTING - B-CAN SYSTEM DIAGNOSIS TEST MODE A ).
