Brake Noise

Scuffing of drums, shoes, and end play

checks are not warrantable

Mack and Volvo

Issue is being closely evaluated by engineering and a production and aftermarket solution is under development.

This is not considered safety related and is primarily due to the shoes made of a more aggressive material and the time

required for a full burnishing has increased.

Thermostat Software Update

Mack (CHU, CXU, GU, TD, MP7, MP10)

Volvo (VN, VHD, VAH, D11H, D16H)

During severe weather conditions, fault may display during engine warm-up and indicate an issue even when the cooling system is performing normally. DTC can be removed from the

diagnostics by updating MID 128 (SA-0) Software See FSB 284-038 (Same FSB # for both brands)

DEF (Diesel Exhaust Fluid) lines

At top of DEF tank, lines may break in

extreme cold temperatures

Mack and Volvo

When trucks are not run on a daily basis, in temperatures below -11 C (-12 F), DEF tank levels should be no higher than

1/2 a tank, to allow for expansion as DEF freezes. Failure to do so may lead to damage to DEF lines or connections.

I-Shift / M-Drive Repairs Mack and Volvo

All 3 modules will be allowed for use on warranty repairs: 1. Complete unit should still be used if cost of repairs is

75% of reman 2. Basic unit (less shift housing & TECU) will be best

option for tow damage 3. Short unit (less shift housing, TECU, & auxiliary range

section) will be best option for bearing failure or main shaft synchronizer issues.

Parts will be available for dealers to repair auxiliary range section in addition to a complete unit. Dealer is responsible to assess unit and select best repair option. Technicians must attend on-line training before using modules for repairs. Dealer assumes all risk of assembly workmanship. Ref: SB 431-12 (short) and SB 431-13 (basic), PSM-13-V-NA-10 and V42-1 for Volvo p/n and PSM13-NA-13 and M42-1 for Mack p/n.

Fuel Tank Ventilation Filter Kit mounting with cab-mounted

exhaust

FSB 234-014 – installing a stanchion

mounted fuel tank vent kit for trucks with cab-mounted

exhausts

Mack and Volvo

To install a stanchion mounted fuel tank vent kit on trucks with cab mounted exhaust, identify a suitable fixed mounting point preferably near the back of the cab at a point above the fuel tanks; high enough to allow for the vent line to be routed on an upward slope. If a body is being mounted to the truck a fixed point on the body near the back of the cab and above the tanks can be used as well. Route the vent lines in an upward sloping direction away from the tank so fuel can drain back to the tank from fuel tank slosh. Do not leave any droops or low points in the hose routing that would allow fuel to sit or collect in the vent line.

SPN 84 / FMI 19 VSS sensor fault Mack (M-Drive) and Volvo

(-Shift)

As a short term solution do the following: Install a 2mm gasket, p/n 977935, between a known good AMT Vehicle Speed Sensor and the Automated Maunaul Transmission. For parts marked 21643804 up to date code 49 12 (w1249), replace with p/n 21643804 date code 50 12 (w1250) or greater and add gasket p/n 977935. For parts marked 21643804 date code 50 12 (w1250) or greater, remove sensor add gasket p/n 977935 and re-install. Sensor torque is 25 +/- 5 Nm

Release the truck to the field. A long term solution is being developed and further service documentation will follow once completed.

Remember to provide both the New and Old transmission model and serial numbers.

SPN 412 / FMI 0, 5, 15 EGR Temp Sensor Mack and Volvo

For SPN 412 – FMI 0 fault code – continue diagnostic procedure as normal (if SPN 412 – FMI 5/15 codes are not present), issue could be EGR cooler related. SPN 412 – FMI 15 – If above 15 counts, replace sensor (no diagnostics needed –fault code printout must be attached to the claim as proof the codes are there). SPN 412 – FMI 5 – If above 15 counts, replace sensor (no diagnostics needed–fault code printout must be attached to the claim as proof the codes are there). FMI 5/15 trumps the FMI 0, if combination of these FMI’s.

condition

engines built with software later than W1307, if a stumble issue at 1200-1600

when cold and under light load

Mack and Volvo

Do not spend any time on this issue right now - goes away when the engine reaches operating temperature. Do not

replace injectors, VCB valves or major engine components as the issue is software. A fix will be incorporated in an upcoming software campaign. The chassis can be released for now till the

campaign is released. This creates no engine damage. Most customers will not even notice the issue because it does not

happen under load.

When programming a Cummins ECM via INSITE software, perform ECM Image, to capture the programmed customer

parameters in the Cummins ECM. If done at a Cummins distributor, request a printout of the expanded parameter list.

This fault code does not mean the system has issues, it simply means that the truck is not signed up to an active account in

Volvo Link. Until the truck is signed up and activated, TGW will not communicate.

AMT operational issues or clutch calibration issues after

engine or flywheel hsg replacement

Vehicle will not move and engine RPM will not increase when

shifter put in gear, or AMT will not calibrate

if TECU reprogrammed

Mack and Volvo

Wrong flywheel housing may have been installed. The AMT flywheel hst is not the same depth as the non-AMT housing. This causes a large change in the X2 value (30.6 mm) that is

higher than the saved X1 value (26.0 mm). Check VCADS clutch wear check, test. Verify flywheel hsg PN prior to installation of

new hsg or repl engine.

CAC Flux Contamination, may result in engine surge,

especially at low idle or low RPM. Contamination of mixer flow ports with a gray/white

crusty substance.

Fault Codes 2776 and 1861 (Ref Cummins’

TSB101120) Mack and Volvo

Recommendation is to send the CAC to a radiator shop to be cleaned locally, do not replace the CAC. Claims will be accepted

for cleaning or replacement of the affected Cummins parts along with the sublet cleaning of the CAC, using the CAC as the

causal part number.

X Tip to attach a jobcard to

eService PTT 1.12 Mack and Volvo

Any time you perform testing within PTT, a new job card should be made. After a fault code read out and any testing has been performed if you wish to attach the job card to an E-service case you will need to finalize the job card. Once you have finalized the job card click onto the job card tab at the top of the PTT screen, in the drop down menu click on Export. Click on to highlight the report you wish to export, next check the box named Export to HTML then click the Export tab. A box will appear and you will have the choice where you want to save the file, it is suggested to save the file in your (C) drive. You can name the file anything you wish. When you go into your E-service case and click on attachments you will be asked to find the file you wish to attach, simply go into your (c) drive and find the Jobcards file, open the file and click on the jobcard you wish to attach. If your file is too large to attach to the case then you will need to convert the file to a compressed zip file then you will be able to attach the file. To convert a file to a compressed zip file simply left click (one time) on the file to highlight it, and then right click. In the Drop down menu select (send to), then select Compressed (zipped) File. A compressed version of the file will be created allowing you to attach it to the E-service case.
