P0381 code, new GPCM?
Hi all,
I got a SES light on my dash the other day. I pulled the codes and got a P0381 and a P0603. Forscan shows
===PCM DTC P0381===
Code: P0381 - Glowplug lamp circuit
Module: Powertrain Control Module
Diagnostic Trouble Code details
Glowplug lamp circuit
This DTC may be caused by :
Open circuit.
Short circuit
Possible causes are:
Harness wiring
Indicator bulb
PCM
Inspect connectors for signs of damage, water ingress, corrosion, etc.
I'm assuming this means I need a new GPCM, correct?

I didn't know if there was a common issue with the GPCM, or if there was a common cause for the code. If there is, I'd start there before diving down the rabbit hole of diagnosing everything.
