DTC P20BE: REDUCTANT HEATER B CONTROL PERFORMANCE
| Description: | The PCM carries out a functional key ON, engine running (KOER) self-test for the glow plug system. During that test the PCM enables the glow plug control module (GPCM) 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. | ||
