hi got to look at one of these units reported microprocessor fault anyone had similar :confused:problems

[SteinarN]

What is the symptom?

[abbsnowman]

Need more info to help you.

[cadwaladr]

hi steinarn the problem now i have looked at the unit is the in cab control is not working all fuses ok connection between contol and unit is fine power at relay board

[SteinarN]

Do you get an ERR4 code?
Or doesn't the cab command react when you push the push buttons?

[cadwaladr]

the in cab control is not showing any display have checked the interconnecting cable for continuaty

[SteinarN]

Have you tried to short this two pins in the plug at the Cab Command cable?

[SteinarN]

And if that didnt help, have you tried to short the mating part to this plug in the El-box?

If it starts when you short the plug at the Cab Command end the fault is the on-off switch in the Cab Command. If it starts when you short the mating part to the cab command cable in the el-box then the fault is the cab command cable.

And if nothing of this helps you can try to replace the RCR1 and RCR2.

[SteinarN]

I suppose when you say the cab comand doesnt show anything you mean the reefer is totaly dead and doesnt try to start either.

[cadwaladr]

yes the in cab is dead and no voltage either live or earth there either i stripped down the box and the switchj checks out ok the switch on the unit frame is set to on by the way someone else has told the client the micro is faulty

[Boss302]

Might sound stupid but is the on/off toggle switch on the control box on?

[cadwaladr]

yes ,it is no it did not sound stupid sometimes the obvius gets forgotten

[abbsnowman]

Do you have a wire schematic? I know these machines inside out as does alot of people here. I would be willing to help you if you retract your insultive posts in the other forum. We are all here to help and if everyone has a quick look they may see why I am hesitant to help someone whom belittles others on this site.
Fix your bad so we can move on!
Cheers

hi and tak

[AIDANMC2006]

Whats the err.4 code? I got it today on a supra 522, wrecked my head

[Boss302]

Err4 means there is a communication error between the micro and the cab command. Usually a problem with the cab command cable.

[radekklimat]

Take off the cover plate and replace the micro-small, round fuse
Located next to the relay power supply mode
It looks like a bridge rectifier GretzSłuchaj
