DTC DESCRIPTION P20BE (PCM) - REDUCTANT HEATER B CONTROL PERFORMANCE
| Description: | The PCM enables the Glow Plug Control Module (GPCM) during a self-test which monitors the conductance of each reductant heater during peak power and compares this conductance to an expected threshold. When the GPCM detects that the reductant heater conductance is out of tolerance with this threshold, the GPCM sends a message to the PCM which sets this DTC. | ||
