MKZ with High Intensity Discharge (HID) Headlamps and Milan

WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

When the Smart Junction Box (SJB) detects the headlamp switch in the HEADLAMPS ON position and the multifunction switch in the LOW BEAM position, the SJB provides voltage to the LH and RH headlamp relays. When the headlamp relays are energized, voltage is switched to the headlamps.

For MKZ with HID headlamps, the ballasts then provide the required high voltage to illuminate the HID headlamp bulbs.

DTC Description Fault Trigger Conditions
  • B106E - Solid State Driver Disabled Due to Short Circuit
 A continuous DTC that sets when the SJB has temporarily shut down the output driver. The module has temporarily disabled a low beam output because an excessive current draw exists (such as a short to ground). The SJB cannot enable the low beam output until the cause of the short is corrected, the DTCs have been cleared and a successful self-test is run  .
  • B106F - Module Disabled Due to External Fault
 A continuous DTC that sets when the SJB has permanently shut down the output driver. The module has permanently disabled a low beam output because an excessive current draw fault (such as a short to ground) has exceeded the limits that the SJB can withstand. The cause of the excessive current draw MUST be corrected before a new SJB is installed  .
  • B2A2E - Right Front Lamp Low Beam Circuit Open
 An on-demand DTC that sets when the SJB detects an open from the RH low beam output circuit.
  • B2A2F - Right Front Lamp Low Beam Circuit Short to Ground
 A continuous and on-demand DTC that sets when the SJB detects a short to ground from the RH low beam output circuit.
  • B2A30 - Left Front Lamp Low Beam Circuit Open
 An on-demand DTC that sets when the SJB detects an open from the LH low beam output circuit.
  • B2A31 - Left Front Lamp Low Beam Circuit Short to Ground
 A continuous and on-demand DTC that sets when the SJB detects a short to ground from the LH low beam output circuit.

This pinpoint test is intended to diagnose the following:
