The P0AB9 fault code refers to the Hybrid System Performance. It is related to the generator control module, which consists of three control modules: the hybrid powertrain control module, 14 volt power module, and the drive motor control module. These modules are not serviceable and are part of the generator control module. The eAssist hybrid system has two methods for cranking and starting the engine.

The first method uses a conventional 12 volt system, where the 12 volt starter and battery are used.

The second method utilizes the 115 Volt generator control and battery assembly, along with the starter generator (drive motor).

The drive motor serves as a generator and provides engine power assist. It can also start the engine in auto-stop mode. If the engine fails to restart with the drive motor in auto-stop mode, the 12 volt conventional starter will automatically engage.

The drive motor can quickly rotate the engine to prevent stalling, as detected by the hybrid powertrain control module. In summary, the P0AB9 fault code indicates a performance issue with the hybrid system, specifically related to the generator control module and the starting methods of the eAssist hybrid system.

What are the possible causes for the automobile fault code p0ab9?

If you see the engine light or service engine soon warning light on, the fault code P0AB9 could be the culprit. This code is often caused by a faulty starter generator control module, an open or shorted harness, or a poor electrical connection in the control module circuit. To fix the issue, visually inspect the wiring harness and connectors, checking for any damage or corrosion. Also, be sure to look out for broken, bent, pushed out, or corroded pins in the connectors.

How can I visually inspect the wiring harness and connectors to fix the fault code p0ab9?
