04 pilot bcm location - Honda Cars & Trucks

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)

You will have to have a dealer flash the BCM. If the BCM didn't have the same Vin identification code, the used one will not operate correctly. Each truck has its own unique Flash program

Problem is most likely in BCM, try disconnecting the engine battery for 20 minutes. If problem persists BCM reprogram required.

it could but depends on your problem
there is a few reason to reprogram
change bcm
major repair to wiring
from a service bulletin to correct certain problems.
reprogramm your bcm otherwise for nothing.

Rectangular fuse box in the right side of the engine compartment, before the co-pilot position. Check your car by OBD2 diagnostic tool.

i have envoy 04 and i make a replacement of the BCM and i try to start it but on the control board shows keylock.what should i do please

Hi, my diagram indicates C3 is a brown connector. This should be centered on the back of the BCM. The purple connector is C6, which is the 16-pin interface on the front of the module. You can see pictures here:

This purple connector might not be used on your truck. Please let me know if you have more questions. Sorting out BCM issues can be challenging.

O2 SENSORS LOCATED ON THE EXHAUST MANIFOLD AND ONE EXHAUST PIPE BEFORE CATALYTIC CONVERTER.RADIO NOT SHUTTING OFF PROBLEM IN THE BCM.THE WIPERS WONT SHUT OFF.PROBLEM IN THE WIPER MOTOR OR SWITCH.IF SEAT BELT LIGHT STAYS ON YOU HAVE A ELECTRICAL PROBLEM THIS WOULD BE A DEALERSHIP FIX.
