Defect
The automatic headlamp activation function uses an improperly configured program in the front chassis input/output module. Depending on internal processing conditions at the time the ignition power is switched on, available memory may become insufficient. This causes the automatic on/off function to enter an emergency mode in which the low-beam headlamps remain illuminated continuously regardless of ambient light levels, causing the system to fall out of conformance with the requirements for automatic headlamp activation and deactivation.
Corrective action
On all vehicles, the front chassis input/output module is reprogrammed with the corrected/updated software.
