ISSUE
Some 2009 Edge/MKX vehicles (built 10/1/08 - 1/1/09) and equipped with the Powercode Remote Start Accessory Factory Invoiced Accessory (FIA)
may have an incorrect splice of the remote start harness into the gray parklamp feed circuit. (It should have been connected to the violet/white parklamp
output circuit.) This connection may result in a failed headlight switch. Vehicle symptoms are:
1.
When the vehicle is remote started, the parklamps do not flash when the horn sounds and they do not stay illuminated while the vehicle is in
remote start mode. 2. Headlights turn on after a few seconds delay when the ignition is turned to ON, even if the headlight switch is in the OFF
position.
ACTION
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
1. Remove the driver side front scuff plate, following Workshop Manual (WSM), Section 501-05 and confirm that a white wire from the remote start
module used for parking light output control has been spliced into a gray wire (parklamp feed) looped under the scuff plate/kick panel near the
A-pillar.
a. If white wire connection is confirmed proceed to step 2.
b. If no white wire connection is present this procedure does not apply, do not continue with this TSB.
2. Cut and separate the white wire from the gray wire, and use electrical tape to insulate the exposed gray wire, being sure to extend two (2) inches
beyond either side of the non-insulated section of wire.
3. Splice the white wire from the remote start module into the violet/white wire coming from smart junction box (SJB) connector C2280E, Pin 6.

NOTE
A DIGITAL VOLT OHM METER (DVOM) CONNECTED TO THE CORRECT WIRE WILL SHOW 12V, WHEN THE HEADLIGHT SWITCH
IS TURNED TO PARKLAMPS ON, THEN SHOW 0V WHEN THE HEADLIGHT SWITCH IS OFF. A LOGIC PROBE WILL SHOW POWER
