If the SH-AWD light on your MDX is glowing, it’s an indication that the system has detected an issue. The root cause could stem from various factors, including:

Resolving the SH-AWD Light: A Step-by-Step Guide
To effectively resolve the SH-AWD light issue, a methodical approach is crucial. Here’s a step-by-step guide to help you troubleshoot and fix the problem:

Check Tire Pressure: Ensure all four tires are inflated to the manufacturer’s recommended pressure. Under- or overinflated tires can trigger the SH-AWD light.

-
Examine Electrical Wiring: Inspect the wiring harness for any loose connections, frayed wires, or corrosion. Repair or replace damaged wires promptly.
-
Reset the SH-AWD System: Disconnect the car battery for a few minutes, then reconnect it. This action may reset the SH-AWD system and resolve the issue.
-
Consult a Professional: If the above steps don’t yield results, it’s advisable to seek assistance from an authorized Acura dealership or a qualified mechanic. They possess the diagnostic tools and expertise to pinpoint the exact cause and provide an accurate solution.

Avoid Off-Roading Rigors: While the SH-AWD system enhances off-road capabilities, excessive or aggressive off-road driving can put undue stress on the components, increasing the risk of damage.
