Quick question;

Anyone on here disabled their daytime running lights.
Or is this pre-set on the main ECU ??

Mine has been off road & without power.
Now running the DRL is active.

So maybe ECU has reset to stock settings as they were not active before I took off the battery.

 

The American trucks don't have DRL's. I think the ones sold in Canada do...

 

this info suggests that its hardware related

I must have re-connected the cable to the resistor when I put front end back on.
