Choice program on the West Coast - from company driver to IC

Enjoy the time at home man, how about sending a few of those 3.39/mi loads down here to the southeast!!

 

My darn AWL keeps coming on also. Schneider says no codes but what is this.

 

Thanks, the Tampa area is where we are looking at needing to park. I thought both the truck stops near Tampa charged for parking.

 

Hopefully just a bad sensor, found this. From EPA '07 engines but probably the same deal on yours.

This diagnostic is typically the Motor Control Module (MCM) has detected an impossible temperature shift on the Diesel


Oxidation Catalyst (DOC) inlet temperature sensor. The most likely cause is an intermittent wiring concern.


1. Check fault codes:


a. If SPN 3242/FMI 3 or 4 is active, repair those faults first.


b. If SPN 3242/FMI 3 or 4 is inactive along with SPN 3246/FMI 8, Go to step 2.


2. Connect DDDL 7.05 SP2 or higher.


3. Turn the ignition ON.


4. In the All Voltages Service routine tab, select Start Acquiring.


5. While wiggle-testing the harness, look for abnormal voltage spikes on (pin 115) T_DOC OUT. Once a voltage spike is


detected, isolate that section of harness and inspect for wire chaffing, corrosion, improper connections or physical damage


and repair as necessary. If no voltage spikes are detected, Go to step 6.


6. DOC Inlet Temperature Sensor Test – Disconnect the DOC Inlet Temperature sensor, measure the resistance between pin


1 and 2 of the DOC Inlet Temperature sensor connector (refer to chart for resistance values).

 

Thanks for the info
