Integrated Relay Controller Description

The Integrated Relay Controller Module (IRCM) interfaces with the EEC-IV system to provide control of the cooling fan, A/C clutch, and fuel pump. The module incorporates the ECC power relay which supplies current to the EEC-IV system.

The location of the IRCM for all models is on the radiator support bracket. The operating voltage of the IRCM is between 7-17 volts.

For diagnostic information concerning A/C components controlled the IRCM and/or for the IRCM itself, see the following A/C INTEGRATED RELAY CONTROLLER trouble shooting charts.
