Service bulletin FSB-31-32

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

SB72-402021-06-14. Service bulletin. On Cascadia vehicles built from November 25, 2013, the drain holes at the bottom of the cab doors were enlarged to improve drainage during the e-coat process in the manufacturing plant. The larger holes allow more cold air to flow through the doors, most noticeably in extreme cold conditions.

TSN 01-07c2021-05-13. Service bulletin. Beyond routing and wiring concerns, the PCC system as previously implemented suffers from two timing / reporting issues. One stems from the long boot-up time of the PCC module as compared to the CPC (a.k.a. the 6N4C timer issue), and the other stems from the potential of some PCC modules to lock-up (a.k.a. the NAND flash issue). The timer concern is considered to primarily affect EPA10 units (OBD13 already had a longer timer) and most can be resolved by simply refreshing the CPC software (even if an update is not available). The module lock-up software solution is currently being validated, so the PDC stock is not clean yet. However, lock-up is anticipated to only be present in approximately 8% of PCC modules (based on testing), so (ahead of a campaign), here are instructions on how to reactivate a system, verify proper operation, and drive service actions.
