HAZARD WARNING LAMPS 

NOTE:

The front fog lamp switch is integral to the left multi-function switch/Steering 
Control Module (SCM), which communicates with the Electro Mechanical 
Instrument Cluster (EMIC)/Cab Compartment Node (CCN) over the Local 
Interface Network (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 Front Fog 
Lamps.

CONDITION

the appropriate diagnostic information.

5. Ineffective TIPM inputs or 
outputs.

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

FRONT FOG LAMP DOES 

NOT EXTINGUISH

1. Ineffective feed circuit.

1. Test and repair shorted front fog lamp 
feed circuit if required.

2. Ineffective EMIC (CCN) 
inputs or outputs.

2. Use a diagnostic scan tool to test the

the appropriate diagnostic information.

3. Ineffective TIPM inputs or 
outputs.

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

NOTE:

The hazard switch is integral to the instrument panel switch bank, which 
communicates with the EMIC/CCN over the LIN data bus. Before performing any 
of the following tests, confirm whether the left and right turn signals operate 
satisfactorily. Then determine whether the other functions of the instrument 
panel switch bank are operational. If the turn signals are ineffective or operate 
improperly, or if the other instrument panel switch bank functions are 
ineffective, diagnose and repair those problems before attempting to repair the 
Hazard Warning Lamps.

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 Headlamps. In addition, the TIPM will store a Diagnostic Trouble Code (DTC) 
for an open or shorted headlamp circuit.
