Install the PCM electrical connectors. Tighten the PCM connector screws. Install the left hush panel. Connect the negative battery cable.
    2. CAUTION: Do not touch the PCM connector pins or soldered components on the circuit board in order to prevent possible Electrostatic Discharge (ESD) damage. Do not remove the integrated circuit boards from the carrier.
