NOTE:

(1)

The DTC in parentheses is the Honda code that you will see when you use the HDS. The first 
number(s) before the - (hyphen) is the flash code the D indicator indicates when the data link 
connector (DLC) is connected to the HDS, and in the SCS mode.

(2)

This code is caused by an electrical circuit problem and cannot be caused by a mechanical 
problem in the transmission.
