Gen3 - Installation - Generic Can Cabin Interface Module (CCIM)

Gen3 - Installation - Generic Can Cabin Interface Module (CCIM)

Notes
The CCIM connects the system into the machine electronics and interfaces between the display and the external sensors.
The CCIM along with the backup battery (see Note 1.) should be mounted inside the dashboard, near the rest of the machine electronics. The CCIM and backup battery are designed to be mounted using velcro tape - so it can be mounted to any flat surface. Ensure there is enough space to attach the connectors to the front of the CCIM before attaching the tape.

Once the CCIM is mounted, connect the 26-Pin bulkhead connector of the power/camera harness and the 34-Pin bulkhead connector of the I/O harness to the CCIM. Connect the CCIM to CPIM cable from the CPIM to the 4-Pin CAN connector on the CCIM. The power (+12V & GND) to the CPIM is provided from the CCIM via this cable. The other two internal cable conductors are the CAN communication cables. Ensure the spade battery terminals on the power/camera harness are long enough to reach the backup battery (before securing with Velcro tape). Do not connect the battery terminals yet. The battery terminals will be connected towards the end of the installation. see Note 1. 

Connect the camera cables to the power/camera harness matching the Forward and Reverse camera labels. 


Coil up any loose camera or CCIM cables and store underneath the dashboard. The 8-Pin cable from the CCIM will be routed and connected into the back of the display.

Gen3 Power Distribution
The CCIM is the main power entry point and is the gateway to the rest of the Gen3 system. The 26-Pin I/O bulkhead connector and the power/camera harness are how the CCIM receives supply power. If the system behaves as if no power is reaching the the electronics, then the power/camera harness should be checked first for power connections. The system has a sense circuit for machine key switch activation via the machine radio harness, and this too should be checked for operation.  

If the harness and harness connections check out okay, then the CCIM fuses should next be checked. To accomplish this task, the CCIM lid will need to be unscrewed and lifted. Inside the CCIM are two 3 Amp blade fuses that protect the the system power and the backup battery. see Note 1.  If any fuses are blown, then replace them and screw the lid on the CCIM back into position. Do NOT immediately power the system up. Usually, fuses blow for a reason, so you will need to track through the wiring, until you find that reason. When a reason has been found and remedied for fuses being blown, only then should the system be powered on again. Please keep in mind that the fuses are there to protect the electronics from more catastrophic outcomes and should never be taken out of circuit.

CCIM Not Powering Troubleshooting Steps:
1. With a DC Voltmeter, check for continuous 12 Volts in the CCIM - at the 3 Amp fuses Via CN01-11, CN01-12, CN01-13
2. With a DC Voltmeter, check that the 12 Volt Accessories line is still intact and connected to CCIM CN01-01
3. With a continuity or an Ohm meter, check that the battery ground is connected to the CCIM CN01-06, CN11-07, CN01-08, CN01-09, CN01-10

CCIM Fuse Blowing Troubleshooting Steps:
1. With a continuity or an Ohm meter, verify that none of the 12 Volt harness wires are short circuited to ground.
2. With a continuity or an Ohm meter, check for shorts within the CAN cable conductors. Pin-1 = 12 Volt wire & Pin-4 = Gnd wire  also see Note 1 below
3. With a continuity or an Ohm meter, check for shorts within the four Pressure Sensor cables. Pin-1 = 12 Volt wire & Pin-4 = Gnd wire
4. There are two screw connectors on the back of the Gen3 Display, unscrew the bottom 8-Pin connector.
The display won't boot as the main cable has now been disconnected, but has the fuse stopped blowing. If fuse doesn't blow, then the Display has an internal short. 
Supply Pins below:
Pin 4 = 12 Volt supply
Pins 2 & 3 = Ground

Note 1: Please keep in mind that power is provided to the various Gen3 modules via the four conductor CAN  cables. If any of those units or cables are damaged, then this could easily blow fuses and halt system operation. 

Furthermore, the CCIM also powers the Forward and Reverse cameras (via the 'Camera/Power' port). Both of these devices have a 1 Amp inline fuse within the camera harness. If a short circuit developed within one of these cameras, normally the inline fuse will blow before the CCIM 3 Amp main supply fuse does. However, if some person has previously negligently replaced one of these 1 Amp inline blade fuses with a much higher current fuse, then definitely the 3 Amp CCIM fuses will also blow. 
Notes
 Note 1: Backup battery only used on Gen3 prior to V3.5 display
Warning
Do not disconnect the camera power connectors while the system is running as this will likely blow the fuse. 
Warning
The CCIM enclosure is not weatherproof and can not be mounted outside the cabin
