U210B Lincoln Code – Lost Communication Between Fuel Pump Control Module ‘A’ and Restraints Control Module

Possible Causes

Event Notification Signal (ENS) harness is open or shorted
Event Notification Signal (ENS) circuit poor electrical connection
Radio frequency interference or electromagnetic interference
Faulty Restraints Control Module (RCM)
Faulty Fuel Pump Control Module

الأسباب المحتملة

تسخير إشارة إشعار الحدث (ENS) مفتوح أو إشعار الإخطار القصيرة (ENS) دائرة رؤساء التوصيل الكهربائي تداخل التردد أو وحدة التحكم في قيود التداخل الكهرومغناطيسي وحدة التحكم في وحدة التحكم في مضخة الوقود الخاطئة (RCM)

Possible Symptoms

Engine Light ON (or Service Engine Soon Warning Light)

الأعراض المحتملة

ضوء المحرك (أو خدمة محرك قريبا ضوء تحذير) ضوء)

Description

The Fuel Pump Control Module monitors the duty cycle and frequency of the signal it receives from the Restraints Control Module (RCM). The fuel pump control module determines if the signal on the Event Notification Signal (ENS) circuit from the RCM is a valid duty cycle and frequency. If the duty cycle or frequency is invalid, the fuel pump control module sends a 40% duty cycle signal on the Fuel Pump Monitor (FPM) circuit to report the concern to the Powertrain Control Module (PCM). The test fails when the fuel pump control module is still reporting that it is receiving an invalid duty cycle or frequency from the RCM after a calibrated amount of time.
