|What Does the P0803 Mercedes-Benz Code Mean?

An ignition voltage is supplied to the Skip Shift solenoid coil. The Powertrain Control Module (PCM) controls the solenoid by grounding the control circuit via an internal switch called a driver. The driver supplies the ground for the component being controlled. Each driver has a fault line which the PCM monitors. When the PCM commands a component ON, the voltage of the control circuit should be low (near 0 volts). When the PCM commands the control circuit to a component OFF, the voltage potential of the circuit should be high (near battery voltage).
