P1A69 Code - Starter/Generator Control Module Random Access Memory
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 V DC and 14 V DC buses via the APM, bi-directional 42 V DC to 14 V DC converter. Common causes include Faulty Starter/Generator Control Module (SGCM), Starter/Generator Control Module harness is open or shorted, Starter/Generator Control Module 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 P1A69 Description
When the APM Power Conversion direction is set to a value of 42 V to 14 V, the energy will flow from the 42 V DC Bus to the 14 V DC Bus via the APM. When the Service Charge or jump starting is requested, the energy will flow from the 14 V DC Bus to the 42 V DC Bus via the APM. When the APM Power Conversion direction is set to a value of Off, the APM will be turned off, and not consume or transfer any power. When the APM Power Conversion direction is set to a value of Invalid, the energy will flow from the 42 V DC Bus to the 14 V DC Bus via the APM.
