Code help needed, C0620 HC ??
C0620 HC
I can't seem to find this one anywhere.
This is in my wifes 2000 coupe, I know its a RTD code but thats all I know.
TIA :cheers:

Circuit Description
The ESC module supplies 8 volts to the position sensors. The position sensors use the supplied 8 volts to produce an analog output range of 0 - 5 volts. The ESC module calculates vehicle suspension settings based upon the voltage levels received back from the position sensors. The ESC model monitors for an out of range condition.
Conditions for Setting the DTC
The ESC module senses position sensor output voltage under 0.35 volts or over 4.75 volts.
The condition must be detected for 1 second in 4 consecutive ignition cycles.
Action Taken When the DTC Sets
Stores a DTC C0620 in the ESC memory.
Provides shocks absorber solenoid control based on the vehicle speed only.
Sends a message to the IPC to display the SERVICE RIDE CONTROL message.
Conditions for Clearing the DTC
A history DTC will clear after 100 consecutive ignition cycles if the condition for the malfunction is no longer present.
The ESC module senses the correct position sensor output voltage between 0.35 - 4.75 volts.
Use the IPC clearing DTC feature.
Using a scan tool.
Diagnostic Aids
The following conditions may cause an intermittent malfunction to occur:
An intermittent open or short in the RF position sensor circuit.
Bent, disconnected, or damaged position sensor linkage.
When using a scan tool in order to read position sensor voltage, always make sure the vehicle is sitting with the full vehicle weight on its wheels, Measuring position sensor voltage with the vehicle raised and the wheels hanging may lead to incorrect diagnosis.
An intermittent DTC C0620 may produce a random firm/soft ride condition.
The ESC module uses an ignition cycle counter diagnostic approach to set this DTC. This requires the ESC module to detect the malfunction 4 times before setting the DTC. To disable this feature, use a scan tool to clear all DTCs before performing diagnostic procedures.
If the DTC is a history DTC, the problem may be intermittent. Using a scan tool, monitor the position sensor voltage while test driving the vehicle or moving the wiring and the connectors. This can often cause the malfunction to occur
