Transmission relay help/ expected PCM outputs – Diagnostic Network. Test the glow plug relay by listening for a clicking sound when the ignition is turned on. Causes can include a faulty relay, wiring issues, The ECM power relay is responsible for supplying power to the ECM, which controls various vital functions in the vehicle, such as engine performance, fuel efficiency, emissions, and more. The OBD2 code P0690 indicates a problem with the Engine Control Module (ECM) Power Relay Sense Circuit, specifically that the signal is too high. This helps to regulate the power flow throughout the system, ensuring everything runs smoothly. Although generic, engines differ between brands and may have slightly different causes for this code. With the other probe, you will measure the output from pin 87a. Any how, all ideas are highly appriciated so the cables will be checked. Relay may be faulty. The ECU is already being fed power from the white, and that is the same power to the relay, so why the need for the relay? Is it for an audible diagnostic function, as in you hear the relay click so you know there is power being distributed to the rest of the circuits inside of the ECU? Or am I just missing something? How to fix a P068A code: ECM / PCM Power Relay De-Energized Performance Too EarlyA P068A code is set when the nonvolatile random-access memory (NVRAM) write P0686 – “ECM/PCM Power Relay Control Circuit Low” P0687 – “ECM/PCM Power Relay Control Circuit High” Help Us Help You. Sort by Oldest first Oldest first Newest first Most reactions. That’s because getting no power from ECM to the fuel pump relay could indicate that the ECM is faulty, meaning it has failed or its connectors are corroded. I've replaced the battery with a new one and I removed the alternator to have it checked at the local auto zone.

Unfortunately, changing the ECM relay doesn’t always solve the problem. The new ECM-power relay is installed into the socket and the engine scanned for codes. Start by checking the battery and charging system. Un ECM est chargé de contrôler les fonctions du moteur. It’s important to address this problem The relay is located in the engine main fuse relay control box. The PCM relay is a low-current device that can switch to a high-current device. Check Wiring and Connectors: Examine wiring and connectors in the circuit for damage If you’re experiencing weak battery or low voltage while cranking, it could be due to a faulty Engine Control Module (ECM) power relay or issues with the ECM power relay harness. It is periodically checked by the PCM if the voltage level in the power relay control circuit, which delivers battery voltage to the ECM/PCM, is satisfactory. First I removed ALL fuses, circuit breakers Ground signal comes from the ecm to activate the relay and that is not happening. I chose the coil side because it carries very little current. Terminal 3 Supply Earth Optional earth connection for the ECM’s power supply. In case the engine fails to start. The Saab is a really nice car with no paint damage and low mileage at 52,700 Miles I live In If you’re dealing with the P0689 fault code and your engine light is on, it’s time to take action. Start by using an advanced scanner to identify the low voltage Relay functional test: install the relay and place one DVOM probe in a known ground. So I have hardly any experience with ECM motors. The powertrain relay is a normally open relay Common Causes: Problems often stem from a faulty ECM/PCM power relay, damaged wiring, or poor ground connections. Rick . Examine the wiring Re: Code P0688 ECM Power Relay Load Circuit: (VWAUDITEK) Yes i understand how a relay works when i say "looked at it" meaning the shop checked it i'm sure via a Ohm meter or something of the like, This is a very reptuable shop.
