P1AFA – Drive Motor 1 Control Module Programmable Logic Device Not Programmed

P1AFA Possible Symptoms

Engine Light ON (or Service Engine Soon Warning Light)

P1AFA Possible Causes

Reprogram Power Inverter Control Module (PIM),Faulty Power Inverter Control Module (PIM),Power Inverter Control Module (PIM) harness is open or shorted,Power Inverter Control Module (PIM) circuit poor electrical connection

P1AFA Description

This diagnostic applies to internal microprocessor integrity conditions within the Hybrid Powertrain Control Module (HPCM). The HPCM and each Motor Control Module (MCM) utilize a Programmable Logic Device (PLD) to perform certain input and output functions. MCM 1 programs the PLD with software at every ignition ON event. MCM 1 verifies that the PLD is programmed successfully.
