P0C5D 2017 Chevrolet Silverado Code - Drive Motor Position Sensor Circuit 2 High Voltage
Quick Answer
The generator control module also called the starter/generator control module, is comprised of the following three control modules: the hybrid/EV powertrain control module 1, 14 V power module, and the drive motor control module. Common causes include Faulty Starter/Generator, Starter/Generator harness is open or shorted, Starter/Generator circuit poor electrical connection. 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 P0C5D 2017 Chevrolet Silverado Description
The generator control module monitors the angular position, speed, and direction of the starter generator rotor based upon the signals of the resolver-type motor position sensor. The position sensor contains a drive coil, two driven coils, and an irregular-shaped metallic rotor. The metallic rotor is mechanically attached to the shaft of the starter generator.
At ignition ON, an AC voltage, 10 kHz excitation signal is output to the drive coil. The drive coil excitation signal creates a magnetic field surrounding the two driven coils and the irregular-shaped rotor. The generator control module then monitors the two driven coil circuits for a return signal. The position of the irregular metallic rotor causes the magnetically induced return signals of the driven coils to vary in size and shape. A comparison of the two driven coils signals allows the generator control module to determine the exact position, speed, and direction of the starter generator rotor. The position sensor is a non-serviceable part of the starter generator.
The Diagnostic Trouble Code (DTC) will be set when the Drive Motor Position Sensor Circuit 2 reference voltage is greater than 4.9 V.

Frequently Asked Questions about P0C5D 2017 Chevrolet Silverado Code
1. What does the OBDII code P0C5D mean for a 2017 Chevrolet Silverado?
P0C5D indicates a high voltage issue in the Drive Motor Position Sensor Circuit 2, which monitors the position of the drive motor rotor in hybrid or electric powertrains.
2. What are the common symptoms of the P0C5D code?
Symptoms may include reduced engine or motor performance, illuminated check engine light, hybrid system warnings, or the vehicle entering limp mode.
3. What causes the P0C5D code to appear?
Possible causes include a faulty drive motor position sensor, damaged wiring or connectors in the circuit, or an issue with the hybrid drive motor control module.
4. Can I drive my 2017 Chevrolet Silverado with the P0C5D code active?
Driving with this code is not recommended, as it can lead to reduced performance or further damage to the hybrid system components.
5. How can I diagnose the P0C5D code?
Diagnose the code by inspecting the drive motor position sensor, checking for damaged or corroded wiring/connectors, and using a scan tool to monitor sensor data.
6. What repairs are needed to fix the P0C5D code?
Repairs might include replacing the faulty drive motor position sensor, repairing or replacing damaged wiring, or reprogramming/updating the hybrid control module.
7. How much does it cost to fix the P0C5D code on a 2017 Chevrolet Silverado?
Repair costs can vary, but replacing the drive motor position sensor typically ranges from $200 to $500, depending on labor and parts.
8. Can a weak battery cause the P0C5D code?
While unlikely, a weak or failing hybrid battery can sometimes contribute to electrical issues in the drive motor system, so it’s worth testing the battery.
9. What tools are needed to troubleshoot the P0C5D code?
You’ll need an OBDII scan tool, a multimeter for testing voltage and continuity, and access to the Silverado’s wiring diagrams for the drive motor circuit.
10. Is the P0C5D code specific to hybrid or electric vehicles?
Yes, the P0C5D code is specific to hybrid or electric vehicles, as it relates to the motor position sensor in the drive motor system.
