The P0C4A fault code refers to a performance issue with the hybridEV battery pack coolant pump.

This pump is responsible for circulating coolant to control the temperature of the battery pack. The hybridEV powertrain control module 2 sends an enable signal to the coolant pump, allowing it to operate.

The pump is controlled using a pulse-width modulated signal, with a higher duty cycle resulting in a higher pump speed. During normal operation, the pump provides feedback to the powertrain control module, giving information about the pump speed.

However, if the pump detects an internal fault, it will send this information instead of the pump speed.

The P0C4A fault code indicates that there is a performance issue with the hybridEV battery pack coolant pump.

It is important to address this issue promptly to ensure proper cooling of the battery pack and prevent further damage.

What are the possible causes for the engine light being on in relation to fault code p0c4a?

If you’re seeing the engine light on and the fault code P0C4A, it could be due to a few possible causes. One of them could be a faulty Hybrid/EV Battery Pack Coolant Pump. Another cause could be an open or shorted harness for the Hybrid/EV Battery Pack Coolant Pump. Additionally, a poor electrical connection in the Hybrid/EV Battery Pack Coolant Pump circuit could also trigger this fault code. To fix this issue, you should visually inspect the wiring harness and connectors related to the coolant pump. Look out for any damaged components and check for broken, bent, pushed out, or corroded connector pins.
