Customer Question
I have a truck...

I have a truck in the shop that we have changed the thermistors on and we have evacuated and filled the system with the correct amount of Freon. to fill the system we had to jumper the clutch to make it run. we have one code coming up and the clutch wont kick in. code is spn 613 fmi 14 ac service now fan problem/clogged pipe

Mechanic's Assistant: Sometimes things that you think will be really complicated end up being easy to fix. The Heavy Truck Mechanic I'm going to connect you with knows all the tricks and shortcuts.

Sounds good thanks

Mechanic's Assistant: Anything else you want the truck mechanic to know before I connect you?

Both the mode and temp actuators work on the air box or they move both directions i should say and they blow out all the right vents.

When you retrieve those fault codes from the instrument cluster display, look for a couple other digits that go with those numbers and please post those digits. They actually in some cases break things down right to the wire number and connector pin to investigate. It is a pleasure to help anyway I can.

Here is the chart to go by for troubleshooting.

Diagnostic Chart 'A' (HVAC Diagnostic Trouble Codes)

DIAGNOSTIC TROUBLE CODE

FAULT DESCRIPTION

611 14 9 1

Compressor clutch under current (open circuit)

This Diagnostic code indicates that the current in the compressor clutch circuit is <0.5A. This condition is the result of an open, or a high resistance, in the compressor clutch circuit.

Refer to AC COMPRESSOR CIRCUITS .

611 14 9 2

Compressor clutch over current (short circuit)

This Diagnostic code is the result of a short to ground in the compressor clutch circuit or a short across the compressor clutch solenoid.

Thanks for the updated information but please retrieve them through the instrument cluster so you can get all the numbers as in the examples I posted previously. Just off the top of my head, 2023 is a gauge cluster fault. Further details are available with those other digits that are missing but will be supplied when you access the fault codes through the instrument cluster as I mentioned previously.

I jumper the clutch and it cools and works good and when the psi gets above 250 on the high side the fan kicks in. With the fan on the pressure is 225/30
Customer reply replied 3 years ago
We ran a jumper lead to the ac clutch and it runs fine and at 90 degrees ambient temp. the pressures are at 225/30 with the fan running. at first the fan does not run but when the pressure goes above 250-275 the fan kicks in. with it jumpered it cools good and works good. it just wont even try to engage the clutch at all on its own we have washed all the coolers out and make sure they are clean.

Thank you for the update. The most common thing with these international trucks are the thermistors going bad or the wiring. Also I would look for any restrictions within the system as well causing a problem.

Ask Your Own Medium and Heavy Trucks Question
Customer reply replied 3 years ago
what would the process be to check the thermistors and the wiring. we replaced the thermistors this spring. would i be looking for voltage to them or resistance across them?

Check with an OHM meter for 2500 OHM's compared to a new one. If out of that range, replace it.

I checked with an ohm meter and one is 2300 and the other is 2900 and i made sure the system is clear i can blow air through all the lines, cond, and evaporator

2900 seems a bit out of range but wondering if related to the pressure of the system if installed in the charged system.

with no pressure in the system we have 2500 on one and 2600 on the other. what should I be looking at on the harness side to make sure they are getting what they need on that side
Technician: Daniel Wilson,

That sounds normal then and thanks for the information. Make sure your pressures are within range of the automotive standard 134a charging chart. If that checks okay, make sure there are no restrictions or leaks in the system.... Monitor your pressure gauges on both the high-side and low-side to see what the pressures are doing.... This will help determine if you might have excessive pressure building indicating a restriction in the system. Try blowing all the lines out and components as well.

We flushed the system and installed new thermistors and the pigtails to them. new accumulator and cabin air filter and all the lines are clear. no leaks and with jumper wire to the clutch we have a 200 on the high and 20 on the low and cools good. but the clutch will not kick in on its own ever. still have the same codesblew out the rad cond and charge air and the evaporator and they were clear.

If everything with the wiring and mechanically with the system checks out good with no restrictions and your pressures are all within specs, you very well could have a software related issue with the controller.

is all the software in the module in the dash where the temp control, mode switch, and fan control or is it somewhere under the dash in another controller.
Technician: Daniel Wilson,
 replied 3 years ago

This software is in the body control module or ESC controller in better terms. It is located in some models behind seat and in other models behind the kick panel under the dash.

2006 International 8600 *****************. Customer brought
Customer brought in truck with AC not working, Check Ac on the dash. Found a high ac pressure shutdown code (can't remember the code). Found condenser, Evaporator, and cabin filter full of debris. I blew compressed air through all until clean, cleared codes, test drove, and sent back. After 5-6 hr driving customer complains ac stopped working, ac check light on. I found high pressure code again. Replaced Condenser after noticing a section that was building condensation (I assumed a blockage) Replaced orifice tube and line it sits in (could not remove the orifice). Replaced the high& low schreader valves (noticed weak springs that allowed the seat to move shaken). Replaced Trinary switch for no particular reason. Removed Evaperator from truck and blew out and inspected for leaks. Flushed lines and evap. Replaced accumulator/drier. Charged with 100psi nitrogen and sprayed down entire system. Psi did not drop over 6 hrs. Charged ac 1.9lbs, test drove, and Returned to customer. 5-6 hrs driving customer complains no ac/ light on. Code SPN: 612- FMI 14 Byte 7:23 Byte 8:1. I thought this was a thermistor code and inspected thermistors. Low side thermistor had bare wires at the plug. Installed a thermistor kit for both thermistors, cleared codes, test drove, and returned to customer. Customer drove 5-6 hrs and ac not working, ac check light on. Code SPN 613 FMI 14 Byte 7:1 8:10. I thought this was HVAC control head fault. I found batteries were not tied down correctly and arcing out to the frame. Built a new battery holdown, cleared codes, test drove 3 hrs, and returned to customer. Customer Drove 5-6 hrs Ac stopped working. I test drive the truck to find ac working. I notice at idle when fan engages at 300psi, it pulls high pressure down quickly. When driving at 1800 rpm fan stays on for minutes at a time. Driving at 1900rpm or below 1750 fan turns off and does not engage. Ac blows 25 below outside temp. I am asking for some insight before i send the truck back and have the ac system stop working again. … read more
