This TSB applies to 2012 Honda Civic and CR-V vehicles. The battery may be dead and needs multiple jump starts in order to start the engine. Aside from the obvious concerns regarding battery age, vehicle storage period, faulty alternator, sulfated battery, parasitic draw or loose battery cables, a probable cause is the PCM not selecting the correct charge mode. The vehicle’s battery sensor monitors battery condition and the PCM determines charging mode. Based on customer driving habits and sulfation, the PCM may not be able to select the correct charge mode.
NOTE: Before beginning the repair, make sure that both the HDS and MVCI are updated with the latest PGM-FI software.
