The hazard
On certain vehicles the Intelligent Power Distribution Module (IPDM) assembly contains an Engine Control Module (ECM) relay that has a diode for electrical current noise reduction. The ECM relay may allow silicon vapor to form and over time the silicon evaporates from the diode molding which causes silicon oxide to develop on the ECM relay contact due to arcing. In certain instances, this oxidation could cause engine performance issues (hesitation, rough engine idle, slow start/no-start condition), and engine stalling at low engine speeds which may result in a crash. Correction: Dealers will replace the Engine Control Module (ECM) relay.
