Product Update: IMA Battery Software Update

Background

The current battery control software can lead to IMA battery damage when the HDS is used in the generic mode, or a generic scan tool is used to clear IMA diagnostic trouble shooting codes (DTCs).

The current engine control software will celar the stored learned valuse sofr the CKP (crankshaft position) sensor if an HDS in generic mode, or a generic scan tool is used to clear DTCs.

With the CKP values cleared, the PCM could misinterpret the CKP input at high rpm as ping paired misfire (P0301/P0305) and set these DTCs.

Corrective Action

Update the IMA battery control module and the PGM-FI sofware using the Honda Diagnostic System (HDS)

Software Information

HDS Software Version 1.018.016 or later

Be sure to use the latest software available (curently 2.002.006). If the correct version of the software is not used, the HDS may incorrectly indicate that the system does not need an update.
