P167F 2015 Chevrolet Silverado Code - Battery Voltage Signal Message Counter Incorrect

Quick Answer

The P167F code indicates that the vehicle's powertrain control module (PCM) has detected an inconsistency in the battery voltage signal message counter. Common causes include Corroded Battery Terminals: Corrosion can impede the flow of electricity, leading to inaccurate voltage readings, Faulty Wiring or Connectors: Damaged or loose wiring between the BCM and PCM can disrupt communication, Software Issues: Outdated or corrupted firmware in the BCM or PCM may cause incorrect message counting. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P167F 2015 Chevrolet Silverado Description

The P167F code indicates that the vehicle's powertrain control module (PCM) has detected an inconsistency in the battery voltage signal message counter. This code is primarily associated with the communication between the battery control module (BCM) and the PCM, which is crucial for maintaining optimal vehicle performance. When the BCM sends voltage data to the PCM, it includes a counter that tracks the number of messages sent. If this counter is incorrect, it may suggest that the BCM is not communicating effectively with the PCM, leading to potential misinterpretations of the vehicle's electrical system status.
