Using the HDS (Preferred Method)

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2014 Honda Ridgeline, 2013 Honda Ridgeline, 2012 Honda Ridgeline, 2011 Honda Ridgeline, and 2010 Honda Ridgeline. However, it is still accessible from the selected car via links, so may be relevant.

Connect the HDS to the Data Link Connector (DLC)

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

First method: If multiple DTCs are stored, be sure to follow the instructions in the B-CAN system diagnosis Test Mode A (see TROUBLESHOOTING - B-CAN SYSTEM DIAGNOSIS TEST MODE A ).
Second method: If no DTCs are retrieved, use the B-CAN System Diagnostic Test Mode 2 (see Troubleshooting - B-CAN System Diagnosis Test Mode 1 and Test Mode 2 (without the HDS) ) to check all inputs related to the failure.
