# Service bulletin 22\-01\-041H

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.

## NHTSA's summary

This bulletin provides information related to a Modular Clutch Actuator \(MCA\) compliance software update for P17D249, a permanent DTC that cannot be cleared with the CARB drive cycle. The software update allows the MCA to send the appropriate diagnostics status to the Hybrid Power Control Unit \(HPCU\) so the DTC can be cleared when the CARB drive cycle has been met. Certain vehicles may experience a check engine light.
