Where is heaadlight relay module located - 2004 Audi A8

System Description EKS005BP Control of the headlamp system operation is dependent upon the position of the combination switch (lighting switch). When the lighting switch is placed in the 2ND position, the BCM (body control module) receives input signal requesting the headlamps (and tail lamps) illuminate. 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 headlamp high and headlamp low relay coils. These relays, when energized, direct power to the respective headlamps, which then illuminate. If voltage is applied to a high beam solenoid, the bulb shade will move and a high beam and a low beam are changed. OUTLINE Power is supplied at all times ? to headlamp high relay, located in the IPDM E/R (intelligent power distribution module engine room), and ? to headlamp low relay, located in the IPDM E/R (intelligent power distribution module engine room), and ? to ignition relay, located in the IPDM E/R (intelligent power distribution module engine room), and ? 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) ? through 50A fusible link (letter f , located in the fuse and fusible link box) ? to BCM (body control module) terminal 55 ? through 10A fuse [No. 21 located in the IPDM E/R (intelligent power distribution module engine room)] ? to BCM (body control module) terminal 42 ? through 10A fuse [No. 19, located in the fuse block (J/B)] ? to combination meter terminal 24. With the ignition switch in the ON or START position, power is supplied ? to ignition relay, located in the IPDM E/R (intelligent power distribution module engine room)

Fuse F2.16 30 amp . location inside the vehicle fuse panel . Also use's two relay's , wiper - run/park relay & high/low relay - location under hood fuse box . K-140 & K- 316 . The wiper / washer switch is an input to the GEM module , generic electronic module . The GEM module energizes the the relay's to turn on the wipers .

HERE'S A LINK TO LOOK AT CLIFF. Where is fuel pump relay located on 1986 1995 Mercury Sable Ford Taurus

No driver module shown on the wiring diagram for 89-98 models.
There is an EEC relay that powers the fuel pump relay. The fuel pump relay is grounded by the PCM. The voltage goes from the fuel pump relay thru the inertia switch and on to the pump.

The SSFR (Solid State Fan Relay)Cooling fan relay is located on the left front inner frame just behind the radiator.
The radiator coolant fan relay is located on the inside front of theengine compartment near the left headlight assembly. You have to removethe air filter assembly, then look for a simple square relay with 4wires running into it. It is mounted with 2 screws. It is the onlyrelay at that location. If it has burned, you will need to replace thepigtail wiring harness.
Remove the air box beside the battery a10 mm bolt and the relay is a four prong square box bolted on the framewith two 8mm bolts

Click component location.

Some are located under the drivers side headlight, Removeair cleaner assembly, remove headlight module, remove (plastic)cover(air intake0 with a phillips screwdriver, locate module, removewires (red tab). Some are riveted (like mine), carefully drill ourrivets remove module, install new module,
re rivet or replace w/screws, rehook wires rellace parts removed and you are finished. Even w/rivets job took approx 1 hr

I know on a 83 its located by the glove compartment ,, try looking there

the filaments it the headlights operates alike a fuse so that is why no fuse is needed. your headlight switch has burnt contacts and will be needed to be removed and replaced

All the relays are together in a module,call IRCM module,it is located under the long plastic cover on the top of the radiator. I think the engineering number on it is 12B577 ? if there's a problem with one of the relays,it is serviced as a unit.Check all the grounds at the battery too. A common problem with taurus was corrodid cables,

its not an actual relay is like a relay assembly

Constant Control Relay Module (CCRM)


The Constant Control Relay Module is located at the LH front of the engine.
