Hello,
I have a Cat M318C at which monitor panel is not working.
Can someone help me with an advice and also with an electric schematic?
Thanks

Usually a faulty voltage converter inside, contact this guy for repair.

If you want an electrical schematic then you will have to supply a Serial Number.

 

[Soo]

Serial numberBEB02032

Sorry, it was a phone mistake

 

[Nige]

No worries. Sent you the schematic.

Hello,
Also if someone can help me with a manual?
Thank you

 

[Nige]

Manuals are probably pretty scarce, not many of them were built. Look for Cat Publication reference RENR9120.
It might be available online at one of the sites like scribd where you have to first subscribe before you can download it.

Hello,
Can someone help me with what reprezenta the symbol INH from the picture atach.
Thanks

I did a bit of Photoshop on the label because it appears to me that there are 3 LEDs in that corner of the module.
Are the two LEDs that are now next to "INH" the CANBus + and - lights....?

 

[Soo]

Yes

 

[Soo]

Those two are not leds, The are just the point coresponding to pin on the board.
Thanks

There is nothing shown in the Cat system regarding the internal wiring of the monitor panel. It is simply shown as a box with a machine wiring harness connected to it.
Having looked at the price of a replacement ($4,400 from Cat, $3,600 on eBay) and been somewhat shocked I can understand why you are keen to try to repair it...............

Cheapest I found was $1,799. https://rebuildengineparts.com/prod...r-m313c-m315c-m316c-m318c-m322c-3054c-engine/

Here's a llink to a place in Spain that says they can repair it - http://www.agrotecnocar.com/novedad...7058-06-reparacion-de-monitor-caterpillar-cat
