P1A7A: Understanding The Elusive Hybrid/Ev Battery Charge Balancing System
The P1A7A fault code is related to the StarterGenerator Control Module (SGCM).
The SGCM monitors its internal fluid temperature sensors to control the SGCM coolant pump and SGCM cooling fan. The fault code indicates that the coolant temperature sensor 3 circuit is experiencing high voltage. The internal fluid temperature sensors of the SGCM are thermistors and are not serviceable.
The voltage signals from the sensors are high when the internal fluid temperatures are cold and low when they are hot. The input parameters are not displayed on the scan tool.
FAQ
If you see the engine light on or the service engine soon warning light, it could be due to the P1A7A fault code. This code is usually caused by a faulty Starter/Generator Control Module (SGCM), an open or shorted SGCM harness, or a poor electrical connection in the SGCM circuit. To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
If the engine light is on due to a faulty Starter/Generator Control Module (SGCM), it is important to visually inspect the related wiring harness and connectors. Check for any damaged components and look for broken, bent, pushed out, or corroded connector’s pins. This could be caused by an open or shorted harness or a poor electrical connection in the SGCM circuit. To fix the issue, check the possible causes listed above and address any issues found during the visual inspection.
Ignoring the P1A7A fault code in an automobile, which indicates a faulty Starter/Generator Control Module (SGCM), can lead to serious consequences.
