P1AFB CADILLAC – Drive Motor 1 Control Module Programmable Logic Device Security Code

P1AFB CADILLAC Possible Symptoms

Engine Light ON (or Service Engine Soon Warning Light)

P1AFB CADILLAC 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

P1AFB CADILLAC 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 and 2 verify that the PLD is programmed successfully.
