Service bulletins for the 2022 Peterbilt 536
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.

| 13-065 | 2024-11-05. Service bulletin. SERVICE BRAKES. 13-065 DAVIE4 Chassis Air Leak Testing Info Only A new test is now available in DAVIE4 to properly measure chassis air system pressure decay, provide test results, and pass/fail criteria. Your DAVIE tool must be at version 24.05 or newer for the test to be available. A test procedure document has also been made available that shows all necessary setup and testing procedure criteria (procedure document attached in Links section). The DAVIE4 “Check the air pressure decay rate” test and the test procedure document MUST be followed anytime a chassis comes in for a warranty related air system repair where excessive air system pressure decay is suspected. Warranty claims filed for air system pressure decay may be denied if DAVIE4 test AND test procedure have not been followed. |

Certain 536, 537, 548, and 567 chassis built with 2.1m Medium Duty End of Frame Trailer Connections and Tractor Protection Valves may not meet the standard trailer brake release timing requirements by 0.5 seconds.

Certain 536, 537, and 548 chassis built with 2.1m Medium Duty End of Frame Trailer Connections may exceed the standard trailer brake release timing requirements by 0.5 seconds due to the size of the tractor protection valve fitting and hose. A delay in the trailer brake release can create instability to the trailer and increase the risk of a crash. |

Safety Recall The brake pedal plunger which connects the brake pedal to the brake valve may dislodge after the pedal is fully depressed, and rapidly released (side slip foot brake release). If the plunger in the brake pedal assembly dislodges the driver may be unable to apply the service brakes, which may increase the risk of a crash. |
