U1510 Check Engine Light - Chevy Silverado or GMC Sierra
The U1510 code in a 2018 Chevy Silverado or GMC Sierra typically indicates a communication problem within the vehicle's network, mainly related to the LIN (Local Interconnect Network) bus. This code signals a loss of communication with a specific device on the LIN bus.
The active air shutter system is a component in some modern vehicles, including the 2017 & 2018 Chevy Silverado or GMC Sierra, designed to improve aerodynamics and fuel efficiency. These shutters open and close based on the vehicle's speed and engine temperature to control airflow through the radiator.
In some cases, a loss of communication between control modules might trigger fault codes related to the active air shutter system. If the U1510 code is present alongside issues with the active air shutter, it could suggest an underlying communication problem affecting the shutter system's operation. However, the U1510 code doesn't expressly point to the active air shutter failure but indicates a communication problem within the vehicle's network.

To resolve this issue:
Diagnostic Scan: Start with a comprehensive diagnostic scan using an OBD-II scanner to retrieve the trouble codes, including the U1510 code.
OM129 Pro Scan tool - The scanner used in this video was provided to us for free through the Amazon Vine Review program. It is an excellent entry-level code scanner that is reasonably priced.

Inspect LIN Bus and Connections: Check the LIN bus connections and wiring harnesses for any damage, loose connections, or corrosion that might interfere with communication between modules.

Address U1510 Code: Diagnose and repair the underlying cause of the U1510 code, which involves troubleshooting the communication system to identify faulty modules, wiring issues, or software problems.

Active Air Shutter Inspection: If the active air shutter system is experiencing problems, inspect it separately for any physical damage, obstructions, or malfunctioning components.

Addressing the U1510 code and resolving communication issues within the vehicle's network is crucial, as this might indirectly impact the proper functioning of various vehicle systems, potentially including the active air shutter system in the 2018 Chevy Silverado or GMC Sierra.

Nice video Steve! I think you covered that very well and did a good job explaining the procedures. When the shutters weren't working, did it make you engine run hotter? Thanks!✌🇺🇸

TPMS Sensors are a pain in the Butt. My dash warning light is on more than it's off. Seems like I'm always replacing dead sensors in my tires ! ☹

Those grille shutters are a pain in ass. I can't find an electrician who is willing to take over this issue due to lack of experience with gm cars and required software. Obd scanner is not helpful for them.
