Follow this sequential procedure to locate and isolate the source of the electrical gap without unnecessarily purchasing replacement parts. 1. Analyze with Diagnostic Tools

This unique hexadecimal identifier points directly to the passenger or driver side-view mirror heating circuit sub-system.

: Once the repair is complete, you can clear the code using an OBD-II scanner or by disconnecting the battery for approximately 15 minutes.

The B166A:60 code is typically electrical, involving issues from the mirror glass itself back to the door module. The most common causes include:

Use a scanner (like FORScan) to see if other codes, such as (Lost Communication with Door Control Module D), are present. If U0202 exists, the issue is likely a power/ground problem at the door module. 2. Inspect the Mirror Wiring and Connector Follow this sequential procedure to locate and isolate

As noted in some owner experiences, this code can sometimes be impossible to clear with a standard scanner, even after the physical problem is fixed. In such cases, the fault may have been logged as a permanent or history code. After the repair, the module may need to see a complete key cycle with the system operating correctly before it will automatically clear the code from its memory. A dealer or advanced diagnostic tool is often required to force a "clear all permanent DTCs" command.

Over time, the fragile resistive heating film attached behind the glass lens can degrade, crack, or burn out completely, breaking continuity.

The cost depends on the cause:

Because side mirrors are exposed to external weather, moisture can creep past the housing and oxidize the male spade terminals on the rear of the glass.
