#Fog light switch series
The diagrams below show the electrical circuit specifications and functionality you will need to know when installing a new fog lamp switch for Discovery I or Discovery Series II. Any auxiliary lamps should be powered with the relay. The fuse is a 15 Amp fuse and is designated FUSE 3. Just like the Discovery I, the contacts of this relay are fused. This relay is R130 and is located in the FUSE BOX - ENGINE COMPARTMENT (P108). the BCU does this by energizing a relay (just like with the Discovery I). In this case, if the front fog lamps are off, it turns them on (conversely, if the lamps are on it turns them off). The Body Control Unit computer (BCU #D162) continuously polls the state of the various switches and when it senses that one is closed, it takes the appropriate action. DESCRIPTION UNO MINDA steers ahead as a leading Tier 1 supplier of Proprietary Automotive Solutions to Original Equipment Manufacturers (OEMs). It only makes a connection and completes a circuit when it is depressed. Any auxiliary lamps should be powered with the relay.ĭiscovery II: The Front Fog Lamp switch (YUG102620G) is a "Momentary Action" switch. Any attempt to power lamps directly with the Front Fog Lamp switch will damage the contacts because they are not rated for high current. The contacts are fused (F8) with a 10 Amp fuse and are therefore protected against over current. The high current contact of this relay (K230) is what actually makes the connection to turn the fog lamps on. If you didnt know, very few switches in BMW vehicles actually switch things.they send a digital signal to a controller, and it turns things on/off. Make sure to release the latch when removing the plugs. For both Discovery I and Discovery Series II, these genuine switches are located in the upper left area of the dash.ĭiscovery I: The Front Fog Lamp switch (AMR4138) for the Discovery I is used to energize a relay. I installed the switch in mine years ago.its a simple swap.
The fog lamp switch (as you may guess) turns the front fog lamps on and off.
