What is Ccrm?
What is Ccrm?
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.
Is the cCRM the same as the cooling fan?
The cooling fan went out, but tested it and was ok, so next suspect was CCRM. Opened it and surely the relay was burnt. A friend of mine that deals with electronic components got me a replacement that cost around $5. And yes, performs exactly the same as the original.
What should I do if my Ceiling Fan is not working?
If you are using a remote control, check that the batteries are installed properly and are not dead. Check that the dip switches on the remote and receiver are set to the same frequency. If you’re using a wall control, check the power to the breaker from your control and try working your ceiling fan manually.

What should I do if my radiator fan is not working?
A blown fuse is no big deal, and changing one does not cost a lot of money. If your car’s radiator fan is non-functional, check your car’s user manual and locate the fuse for the radiator fan controller or the fan. The fan itself often uses a big fuse of around 50A, while there might also be a separate small fuse to the fan control module.
Can a constant control relay module ( CcrM ) fail?
There are reports of failures of the CCRM or Constant Control Relay Module. The CCRM has relays and switches inside that control or provide power to the engine cooling fan, AC clutch (to engage the AC compressor), fuel pumpand powertrain control module (PCM).
If you are using a remote control, check that the batteries are installed properly and are not dead. Check that the dip switches on the remote and receiver are set to the same frequency. If you’re using a wall control, check the power to the breaker from your control and try working your ceiling fan manually.
What does the CcrM do in a car?
The CCRM has relays and switches inside that control or provide power to the engine cooling fan, AC clutch (to engage the AC compressor), fuel pumpand powertrain control module (PCM).
Is the cCRM, PCM, or something else?
If there is key on +12 volts there, that also “proves” the CCRM is working. Based upon everything above it seems likely to me that the PCM has many of the normal external signals that it needs. But yet it’s still not showing signs of life.
