DTC B2600: DRL Error: Description

DTC B600 indicates that a system problem has occurred that is preventing DRL system from operating properly. DTC B600 will set when ambient light sensor indicates bright conditions, DRL is configured to have a drop resistor and Ignition 3 is active, DRL relay output is active, and headlights operate improperly (low beams not in DRL range or high beams on) for more than 10 DRL relay on/off cycles.

When DTC B2600 is set, low beams will flicker on/off in bright conditions, DRL relay will turn off and SERVICE VEHICLE SOON indicator will illuminate. DTC B2600 can be cleared when fault state is exited when Ignition 3 becomes inactive. DTC B2600 can also be cleared using scan tool, or history DTC will disappear after 100 ignition cycles if fault conditions do not reoccur.
