P06B8 - INTERNAL CONTROL MODULE NON-VOLATILE RANDOM ACCESS MEMORY (NVRAM) ERROR - DTC CHART

Description: This DTC sets when a concern with the ability of the PCM to correctly store permanent DTCs is present.
Possible Causes: Low battery voltage Battery or charging system concern VPWR circuit intermittently short VPWR circuit intermittently open PWRGND circuit intermittently open
Diagnostic Aids: Check for other DTCs and diagnose those first. Check for aftermarket performance products. Check for an electrical or charging system concern. If an updated calibration is available, update the calibration to the latest level. If an updated calibration is not available, clear the DTCs and repeat the self-test. If this DTC is retrieved after a PCM reprogramming, turn the ignition OFF and allow the PCM to complete a normal power down sequence. If the DTC is retrieved again, install a new PCM. Refer to FLASH ELECTRICALLY ERASABLE PROGRAMMABLE READ ONLY MEMORY (EEPROM) , Programming the VID Block for a Replacement PCM.
