The P0685 code indicates a problem with the ECM/PCM power relay control circuit. The ECM/PCM (Engine Control Module/Powertrain Control Module) is responsible for controlling various functions of the vehicle, including the engine and transmission. The power relay control circuit is a vital part of this system, as it provides power to the ECM/PCM. The P0690 fault code refers to the Electronic Control Module (ECM) Power Relay Sense Circuit being high. This means that the ECM is detecting a high voltage in the power relay sense circuit. The powertrain relay is a normally open relay that is held in the open position by spring tension. Battery positive voltage is supplied directly to the ... In today’s fast-paced world, convenience is key. From online shopping to food delivery, we expect services to be readily available at our fingertips. Before diving into the benefit...The PCM power relay or ECM power relay work as a switch and transfer power to the ECM. However, if the ignition key turns off, the switches within the PCM power relay will not receive battery power. As a result, your vehicle will not operate properly. Also, when a PCM relay stays open, it cannot transfer power to the ECM.The engine control module (ECM), also known as the powertrain control module (PCM), is the main computer that controls your engine's performance functions and ensures your vehicle is operating its best. The PCM circuit board is coded with vehicle-specific software that acts as the brain of the engine, telling it how to run and operate properly.One of the most common symptoms of a faulty ECM/PCM power relay is engine stalling . If your engine stalls while driving or idling, it could be a sign that the power relay is failing. This is because the power relay is responsible for supplying power to the ECM/PCM, which controls the engine’s operation.The third circuit is usually responsible for carrying a signal from the ignition switch. There’s a fourth wire that supplies voltage to the PCM when the relay is grounded and closes. If the PCM detects a high voltage condition on the power relay sense circuit, it will store the code P0690 and illuminate the check engine light.PCM Relay Location by Harryca » Fri Sep 08, 2023 3:03 pm I have a 2007 mk7 RWD 2.4 tdci that I want to replace the PCM relay on (stab in the dark to try and fix a longstanding issue).The Audi J271 is different to some VW's and has more terminals.
