    Hey guys, my keeptruckin eld just got plugged into my 2006 Freightliner CST120 Detroit 60 12.7L engine, and at first it gave a fault code for what I assumed was low coolant because the coolant was actually low.
    Last week I added coolant and drove around for Bout an hour and the fault code remained but also when I started the truck this time I got 2 more fault codes referencing my data link. Can anyone tell me what's the issue and how to resolve?

    Here's the actual fault codes showing on my eld:
    PID-111 1 Coolant Level Intermittent
    SPN-111 1 Engine Coolant Level 1 Intermittent
    SID-231 12 SAE J1939 Data Link Intermittent
    SPN-639 12 J1939 Network #1, Primary Vehicle Network Intermittent
