Code P2536 Dodge Description

The control module continuously monitors the voltage on the Ignition Accessory/Run circuit from the Body Control Module (BCM). When the ignition is in the ACCESSORY or RUN position, the BCM sends a 12 V wake-up signal to the control module. This wake-up signal allows the control module to power up and start functioning before the engine is started. The Diagnostic Trouble Code (DTC) will be set when the control module detects the Ignition Accessory/Run circuit is less than 6 V for 1 min.
