Powertrain Control Module
The PCM controls fuel injector timing and duration, idle speed, ignition and camshaft timing, PCM back-up functions, and other functions. The PCM is located in front passenger footwell area. On RSX and 3.5RL, ECM/PCM is located under right side of dash, behind carpet. On MDX, 3.2CL and 3.2TL, ECM/PCM is located below left center of dash, behind carpet.
NOTE:
Components are grouped into 2 categories. The first category is INPUT DEVICES , which are components that control or produce signals monitored and processed by the PCM. The second category is OUTPUT SIGNALS , which are components controlled by the PCM.
