PARK LAMPS 

REAR FOG LAMPS 

required.

NOTE:

As part of the exterior lighting fail-safe feature, upon ignition ON, all exterior 
park lamps and the headlamp low beams will illuminate regardless of the left 
multi-function switch control knob position if the SCM cannot detect an input 
from the left multi-function switch, or if there is a loss of communication 
between the left multi-function switch/SCM and the EMIC or between the EMIC 
and the TIPM. Diagnose and repair those problems before attempting to repair 
the Park Lamps.

outputs.

3. Use a diagnostic scan tool to test the 
TIPM inputs and outputs. Refer to the 
appropriate diagnostic information.

NOTE:

The turn signal switch is integral to the left multi-function switch/SCM, which 
communicates with the EMIC/CCN over the LIN data bus. Before performing any 
of the following tests, determine whether the other functions of the left multi-
function switch/SCM are operational. If the other left multi-function switch/SCM 
functions are ineffective, diagnose and repair that problem before attempting to 
repair the Turn Signal Lamps.

STANDARD PROCEDURE 

FRONT LAMP AIMING 

VEHICLE PREPARATION FOR LAMP ALIGNMENT 

1. Check for and correct any burnt out bulbs.  

2. If the vehicle is equipped with headlamp leveling, be certain that the headlamp leveling switch is in the 0 

position.  

3. Repair or replace any ineffective, worn or damaged body or suspension components that could hinder 

proper lamp alignment.  

4. Verify proper tire inflation pressures.  

5. Remove any accumulations of mud, snow or ice from the vehicle underbody and clean the front lamp 

lenses.  

6. Verify that there is no load in the vehicle (cargo or passengers), except for the driver.  

7. The fuel tank should be FULL. Add 2.94 kilograms (6.5 pounds) of weight over the fuel tank for each 

estimated gallon of missing fuel.  

8. Verify correct vehicle suspension height.

The procedure that follows will prepare a suitable front lamp alignment screen. 

1. Tape a line on a level floor 7.62 meters (25 feet) away from and parallel to the flat wall that will be used 

as the lamp alignment screen. The level floor will be used as the horizontal zero reference.  

2. An adjacent wall or floor member that is perpendicular to the alignment screen can be used as the vertical 

zero reference. If there is no adjacent wall or floor member that is perpendicular to the screen, tape a 
second line on the floor perpendicular to both the alignment screen and the first line, and outboard of 
either side of where the vehicle will be positioned. This will be used as the vertical zero reference.  

3. Position the vehicle so that the side of the vehicle is parallel to the vertical zero reference, and so that the 

front of the lamp lenses are in the vertical plane of the parallel line taped on the floor 7.62 meters (25 
feet) away from the screen.  

4. Rock the vehicle side-to-side three times to allow the suspension to stabilize.  

5. Jounce the front suspension three times by pushing downward on the front bumper and releasing.  

6. Measure the distance between the optical center of one of the lamps being aimed (head or fog) and the 

floor (horizontal zero reference). Transfer this measurement to the alignment screen with a piece of tape 
placed horizontally to the floor. This line will be used as the lamp horizontal reference.
