Code P2534 Saturn Description

The Body Control Module (BCM) controls the ignition main relay through the control circuit by applying a voltage to the circuit. The control module samples the system voltage on the Ignition 1 voltage circuit from the ignition main relay every 0.1 s.
The Diagnostic Trouble Code (DTC) will be set when the control module detects 6 V or less on the ignition voltage circuit, with the ignition, turned ON.
