Couple of solutions/answers to some of the posts here in general:
I would choose AlfaOBD over Tazer, because AlfaOBD is a far more power tool, and you have more control over what gets changed in the BCM. It’s also the closest thing you can get to a dealer level scan tool, and can connect to all modules.
For Canadian DRL trucks, if you want to just permanently disable DRLs, you would just set CBC Features DRL configuration to NO DRL. This will shut them off until you use AlfaOBD to change that setting again.
If you want to set them up like a US market Truck, you would set CBC Features DRL configuration to OPTIONAL, and set CustSetMenu 1 daytime running lights CSM Present to YES. This will put the setting in the radio to toggle them on/off whenever you want.
The accent lights can’t be toggled on/off via any type of setting equipped on the truck, but you can disable them with AlfaOBD by setting CBC Extern.Light Calib. Signature light present to NO.
If you want to configure the accent lights to be the DRLs (only come on in gear), and to be brighter than what they are from factory, make the following changes:
CBC Features DRL Configuration- OPTIONAL
CBC Features DRL Lamp Location- DEDICATED
CBC Features DRL Dropout Enabled- YES
CBC Extern.Light Calib. Signature Light Present- NO
CBC Extern.Light Calib. Left Side (and right side) DRL Voltage Target- 7.4 (but can be raised)
CustSetMenu 1 daytime running lights CSM Present- YES
The above settings will make the upper and lower LED accent strips the DRLs (no other lights on). They will only come on in gear, they will be brighter than they were as accent lighting, the accent strips will “drop out” on the side that the turn signal is being used on, and they can be toggled on/off in the radio settings.
