Pin # location in Crash Control Module (CCM) socket

[Gene in NC]

Pin # locations in Crash Control Module (CCM) sockets? Circuit and signal for control of hi beams goes into the CCM but nothing comes out to the LKM pin #1 to pick the b+ output from pin #20 to power hi beams. See link for details on LKM and problem this '89 525 (12/88).

Signal to CCM is verified by lighting of "hi beam on" indicator.

pretty sure CCM is "Check Control Module" not crash control lol

Thanks, Jon K. This prob is confusing enough w/o using confusing terminology.

Bump.

I only have a few pins at the moment which you can exclude from you problem:
Pin 26 at the green plug is for 'door open contact warning' at passenger door.
Pin 1 at the blue plug for same purpose at driver door.
Pin 5 at the blue plug is for both rear doors for same purpose.

Now you have some pins less to check on the check control module.


LKM-L and LKM-B pin -out

1 High Beam stalk at steering wheel
2 terminal 30 (continious power)
3 switch low beam/dip light
4 data to CCM = check control module
5 data to CCM = check control module
6 F1 terminal R, IC supply
7 from k7 P2 - tail light right

8 tail light right
9 tail light left
10 parking light right
11 parking light left
12 from brake light switch

13 brake light left
14 switch licence plate light on
15 3rd brake light
16 fog light front left
17 F7 15A, terminal 30
18 fog light switch
19 rear fog light switch

20 high beam via fuse F13, F14
21 low beam left F10
22 low beam right F11
23 check via CCM + CC + OBC (check control module-check control-on board computer)
24 ground
25 data to CCM

26 from K7P6 tail light left
27 from K7P9 parking light right
28 from K7P5 parking light left
29 brake light right

30 licence plate right
31 licence plate left
32 fog light right, front
33 fog light right, rear
34 fog light left, rear
35 F8 15A for rear fog light

Note: this is the ECE/EU version, some pins might be missing in other versions. But the set - up will be the same. So for the US LKM probably the pins for rear fog light might not be there respect. not connected internally.
Depending on year of production and the makers of the LKM the internal parts look different, but the pins are always for the same function.

The pins in one row are 1 - 19
and the other row
20 - 35

Bill R once posted the CCM pinout, but the pic does no longer exist

Shogun, thanks for the post, but here's my apparent problem.

Bentley wiring diagram (EWD 163) does not show circuit directly from "High Beam stalk at steering wheel" to pin #1 in the LKM.

Circuit shown is:

Combination Switch on stalk at steering wheel through high Beam Indicator to ground and to Crash Control Module on "wht" wire.

Crash Control Module switch:

Normal position connects "yel/gry" to #1 in LKM for High Beams.

On connects "red/wht" from B+ to "yel/gry". Flashing of High Beams for Impact/Accident is controlled by "wht/blu/yel" from Crash Control Module to Hazard Warning Switch.


LKM #20 is output for High Beams.


This is correct logic for the High Beams. Been there done that with the impact. Ran over GM torque converter from wreck. If I remember correctly Crash Control flashes the High Beams and beeps the horn until the ignition is turned off.

Not crash control module, check control module.
I just found the wiring diagram of the CCM, see page 12 and 13, that part is in English.

and here the final version, CCM pinout

If you look very careful at the plastic of the green and blue plug, you see the numbers 1.....13
and 14......26
So you know where to count

Final, sorry but it was the Crash Control Module (Bentley) or Crash Alarm Relay (REALOEM).

located to the right of CCM in the Engine compartment fuse box, look for N17 in the picture.

BUT!!!! Just noticed from 88 drawings that models up to 2/89 does not have a Crash Control Module in the middle of the High Beam Light control line, but the Header Lights control line. Models 3/89 and up changed the control to the High Beams, and those are the drawings I posted.

In your 12/88 car, there should be a White wire straight from the combination switch to the LKM pin 1. If you still do have Crash control in High Beams, may be you have a wrong date for your car.

Just let me know if you still need a Crash Control Module pin location, diagram, and for what model year.

Door jamb date of problem 525 is 12/88. Donor car is 525 3/89. 12/88 has Crash control proven by:

1) Worked in crash.
2) Donor part swapped in solved the no hi beam problem.

Note module in problem car was the original NLA design. Donor module was the replacement design.

THink I'm done except for replacement module for donor.

in effect till 02/89 (see http://www.e38.org/e34/e34_88_etm.pdf), the Crash Control Module acts over Low Beam Headlights instead of High Beam. So the drawings have a bug, somehow it doesn't surprised me, as it wouldn't be the first catch.

Edit: By the way, the bad module should be fixable, probably cleaning contact between Pin 3 and pin 9, or resoldering its pins to Circuit Board will do. See Pin location for its socket.
