Anyone know if there is a similar TSB for the ILX? My battery seems weak. It didn't start the other day in -20c, which admittedly is cold but not cold enough that it shouldn't start..
The Battery Is Dead and Needs Multiple Jump-Starts
The vehicle has sat for at least two days, has a dead battery, and needs multiple jump-starts to start the engine.
A dead battery could be normal depending on the battery condition, battery age, and how long the vehicle has sat. This software update will have no effect on these conditions.
A jump-start should only be used to get the vehicle to a service station or dealer. It should not be used to fully charge the battery.
There are many other possible causes that a vehicle needs multiple jump starts such as a faulty alternator, a faulty or sulfated battery, a parasitic draw, or loose battery cables.
If a battery is sulfated, the sulfate makes charging the battery more difficult. After the battery is properly charged, the effect of the sulfation is reduced so that in most cases, the battery will not need another jump start.
The vehicle’s battery sensor monitors battery condition and the PCM determines charging mode. Based on the sulfation of the battery and customer driving habits the PCM may not select the correct charge mode.
