# Service bulletin 20505

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.

- Type: Service bulletin
- NHTSA id: 10177767
- Published by NHTSA: 2020\-08\-04

## NHTSA's summary

Certain International CV Series trucks may not comply with Federal Motor Vehicle Safety Standard \(FMVSS\) 105 S5.3.1.C or Canada Motor Vehicle Safety Standard \(CMVSS\) 105 S5.3.1. The ABS MIL should be illuminated when there is a loss of communication between the Electronic Brake Control Module and the Body Control Module \(BCM\). If the ABS MIL does not alert the driver in the unique situation of a communication loss, the driver may have no indication of inoperative ABS or Automatic Traction Control \(ATC\) functionality, which may increase the risk of a vehicle crash while operating on slippery road conditions.
