P1A9A Saturn Code - Starter/Generator Control Module Hybrid Battery Current Sensor Circuit Low Current
Quick Answer
The purpose of the Accessory Power Module (APM), integral to the Starter/Generator Control Module (SGCM), is to control the amount and direction of energy flowing between the 42 volts DC and 14 volts DC buses via the APM, bi-directional 42 volts DC to 14 volts DC converter. Common causes include Faulty Starter/Generator Control Module (SGCM), Starter/Generator Control Module (SGCM) harness is open or shorted, Starter/Generator Control Module (SGCM) 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 P1A9A Saturn Description
The Starter/Generator Control Module (SGCM) controls 2 functions in these DTCs. DC voltage is transformed into three phase AC power to the electric machine interface. In this case, energy flows from 36 volt to phase1, phase2 and phase3. The second case shall be generating, where the three phase AC power is used to charge the 36 volt battery pack. In this case, energy flows from phase1, phase2 and phase3 to 36 volts.
What are the Possible Causes of the DTC P1A9A Saturn?
- Faulty Starter/Generator Control Module (SGCM)
- Starter/Generator Control Module (SGCM) harness is open or shorted
- Starter/Generator Control Module (SGCM) circuit poor electrical connection
