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. Ground for the pcm relay is supplied by the pcm pin 33brn/wht. Fuse 39 supplies power into the relay for both the coil and load (terminal 86 30) which should be hot at all times. Pcm pins 2 4 6 are ground from ground 103. Yes, I have 12v at 76 (12.6ish).Fuse 39 is good and has 12v . This can indicate a problem with the relay or its circuit. Possible causes of the P0688 code include a defective PCM power relay, a faulty PCM, and a blown fuse or fusible link. Some symptoms of the P0688 code include an illuminated check engine light, the vehicle refusing to start, and the vehicle stalling. 1. 2000-2001: Daytime Running Lamps Diode. 1998: Anti-Lock Brakes Indicator Diode. 1999: Not Used. 2.
