System Description EKS0058X Control of the fog lamps is dependent upon the position of the combination switch (lighting switch). The lighting switch must be in the 2ND position or AUTO position (LOW beam is ON) for front fog lamp operation.When the lighting switch is placed in the fog lamp position the BCM (body control module) receives input signal requesting the fog lamps to illuminate. When the headlamps are illuminated, this input signal is communicated to the IPDM E/R (intelligent power distribution module engine room) across the CAN communication lines. The central processing unit of the IPDM E/R controls the front fog lamp relay coil. When activated, this relay directs power to the front fog lamps. OUTLINE Power is supplied at all times ? through 15A fuse [No. 43, located in the IPDM E/R (intelligent power distribution module engine room)] ? to front fog lamp relay, located in the IPDM E/R (intelligent power distribution module engine room) ? through 15A fuse [No. 34, located in the IPDM E/R (intelligent power distribution module engine room)] ? to CPU (central processing unit) in the IPDM E/R (intelligent power distribution module engine room).
