My 2022 GMC Canyon has code 42B, described as “Cloth interior trim: Green/Blue (B) (Arena 98). This code identifies the factory upholstery material, color combination, or interior trim specification” I understand the basic definition, but I am interested in the practical effect during normal driving, towing, or highway use.

The wording may be abbreviated because these were originally production codes rather than consumer descriptions. “Cloth interior trim: Green/Blue (B) (Arena 98). This code identifies the factory upholstery material, color combination, or interior trim specification” is a reasonable plain-English reading, but the exact implementation should be verified for the 2022 model.

If the feature is listed but not working, scan all related modules before assuming it was removed. A stored fault, replacement module, or configuration mismatch can make original equipment appear absent.

I have seen this on a similar GMC Canyon. The basic description was correct, but one related feature was part of a separate package. I would not assume the code includes every item mentioned in marketing material.

The safest interpretation is the one tied to the exact VIN, model year, platform, and market. In general, 42B matches “Cloth interior trim: Green/Blue (B) (Arena 98). This code identifies the factory upholstery material, color combination, or interior trim specification” but the included hardware can vary between applications.
