    Default What is a CCRM

    Do our cars have a CCRM? What does it do? Where is it located?

    CCRM stands for Constant Control Relay Module. Not sure what you are referring too as far as our cars go, they are used many places.

    Why?

    Not positive our models have them. But here's what I found:

    The Constant Control Relay Module (CCRM) interfaces with the Power Control Module (PCM) to control the cooling fan, A/C Clutch and fuel pump. The module also includes the Electronic Engine Control (EEC) relay to provide power to the PCM. It's basically a metal base with plastic cover that serves as home for a circuit board with a number of integrated relays.

    Typically it has 4 or 5 relays.

    1. PCM relay
    2. High speed cooling fan relay
    3. Low speed cooling fan relay
    3. Fuel pump relay
    4. A/C clutch/compressor relay

    I am having electrical issues. There is a post just down from this one on my problem and a CCRM was brought up on a phone conversation I had. Just wondering if that could be the issue?

    CCRM (Ford part# 1R3Z 12B577-AA)
    located in the passenger side fender. Right behind the hole where the air snorkel comes through the fender. The CCRM controls alot of functions in the engine area, not just the fuel/ignition system. I had to remove the passenger side fender to get to it though.

    My starter or maybe just ignition switch, some radio functions, power windows, and maybe some other things do not work. All fuses are good in both power distribution box and fuse panel, but not sure how to test relays. Could the CCRM cause that? Thanks

    you may have screwed up your anti-theft system
    try this to deactivate system and see if it starts
    1. press unlock button on transmitter
    2. turn key in door lock to unlock
    3. turn programmed "pats" key in ignation lock cylinder to on

    just a guess

    Jeff, I think you are on to something, but I did do the things you said and still didnt work. I tried both keys. My car has active anti theft too, but not sure if that matters. The PATS light on the dash still flashes every two seconds, but continues to do it when the key is in the ignition. I am lost!!!

    got to ask the dumb question, do you have any dtc codes ? if tuner does not work (turn on when you plug in )

    i think that suggests no power/ damage to the pcm

    active theft should only disable the starter

    pats light stays on, power blocked to ignition switch to activate starter

    the CCRM is only a group of relays,testing relays, i believe, involves voltage / ohm readings at different pin locations.

    you have strange areas for loss of power

    try this, go to the bussed electrical center, i will give you seven fuses to check, start with F4,F8,F10,F14,F16,F43,F65
    this group of fuses is related to the electrical problems you are having, hoping F4 is your problem
    deactivation of passive theft won't work if pats light stays on

    There is no CCRM in 05+, all that stuff is in the BEC now.

    As stated, symptoms suggest a powerless PCM at least.

    I would suggest checking the PCM relay too, is the same as others in the BEC so testing would be simple.

    I'm with Lito on this one. I'd take a test light and go through the fuse box and look for anything blown. Also check power at the PCM.

    No that is the SJB, the BEC is the big fuse/relay box in the engine bay.

    My Predator comes on when I plug it in, but says unable to read codes. All fuses in BEC are good and I have power there. In the fuse panel (passenger kick panel) I do not have power at 19 (PCM relays, PATS) with key in any position. I didnt check all of those fuse ports for power, but I checked a couple to make sure power was getting to it. All fuses are good there too. Its about to get a tow to Ford dealer $$$$$$$$$$$$$$$$$

    Got it. When repinning inside the BEC for the additional driver module i pulled the wrong wire. Complete stupid mistake. I did it right the first time but messed it up the second. Thanks for all your help gents
