Service bulletin PIC5468B

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 Preliminary Information communication provides information to the technician about vehicles with a spongy brake pedal after a hydraulic brake component was disconnected or replaced. The brake lines between the master cylinder and the antilock brake system module are routed higher than the master cylinder. If air enters the system it will travel to this high point if the system is opened for a repair. The technician will need to perform an automated bleed procedure using the scan tool to ensure all the air is purged out of the hydraulic system.
