P1A8A: Understanding Your Hybrid Battery’s Health
The P1A8A fault code indicates that the 42-volt system voltage is high. The Accessory Power Module (APM) supplies energy between the high voltage, 300-volt, direct current (DC) and intermediate voltage, 42-volt, DC to support the Electric Power Steering (EPS).
The APM receives a 42-volt enable command from the Hybrid Powertrain Control Module (HPCM) over the high-speed hybrid GMLAN communication circuit.
The 42-volt APM functions will only run when the 42-volt APM enable is active on the high-speed hybrid GMLAN communication circuit.
FAQ
If you see the engine light on or the service engine soon warning light, it could be due to the P1A8A fault code. This code is usually caused by a faulty Accessory Power Module (APM), an open or shorted APM harness, or a poor electrical connection in the APM 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.
