0 Mackpro Posted June 25, 2023 Share Posted June 25, 2023 In the top fuse box. Towards the left by the flasher.

0 Mackpro Posted June 25, 2023 Share Posted June 25, 2023 Also, don’t throw it away. Keep it in case you want enable it again. I believe that little module/relay cost about $300 Quote Link to comment https://www.bigmacktrucks.com/topic/72978-drl-relays-on-2021-mack-granite/#findComment-533572 Share on other sites More sharing options...

0 Mackpro Posted June 25, 2023 Share Posted June 25, 2023 Your correct , I forgot that the GR , Athem and Pinnacle all use the LCM light control module now. There are about 6 fuses for the LCM . We have never found out what fuse does what. I’m thinking it’s a parameter in the LCM that can be turned off with Tech Tool. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/72978-drl-relays-on-2021-mack-granite/#findComment-533576 Share on other sites More sharing options...
0 vinny933 Posted July 19, 2023 Share Posted July 19, 2023 I was looking around in tech tool and saw you can turn them off with it Quote Link to comment https://www.bigmacktrucks.com/topic/72978-drl-relays-on-2021-mack-granite/#findComment-535155 Share on other sites More sharing options...
