How to Replace a 93 Honda Accord ICM

The Honda Accord was introduced in 1976 and is still part of the Honda lineup today. The ignition control module, or ICM, on a 1993 Honda Accord is replaceable and located inside the distributor. The ignition control module takes the signal from the crankshaft sensor and controls the firing of the coil. It automatically senses engine speed and advances or retards the spark, as necessary. Replacement is not difficult and requires minimal tools.

Things You'll Need

  • Phillips screwdriver
  • Needle-nose pliers
  • Ignition control module
  • Lift the hood and remove the distributor cap, using the Phillips screwdriver. Pull the rotor off. Lift off the plastic cover.

  • Hold the new ignition control module up close to the one in the distributor, so it is positioned properly when installed. Pay particular attention to the four wires -- make note of their color and location. Remove the two wires located on the top of the ignition control module, using the needle-nose pliers.

  • Remove the piece of plastic over the screws on the outside of the distributor that secures the module. Remove the two Phillips screws that pass through the distributor housing into the module, using a Phillips screwdriver.

  • Lift the ignition control module out of the distributor enough to disconnect the two side wires, using the needle-nose pliers.

  • Install the new module by plugging in the two side wires. Lower the module into the side of the distributor and align the two holes with the ones in the distributor housing. Install the two screws through the housing and into the module and tighten them snugly with the Phillips screwdriver.

  • Plug the top two wires into the module. Install the plastic cover that keeps oil from getting to the module. Push the rotor down on the driveshaft. Install the distributor cap and tighten the screws.
