WARNING: This page is about a different car, the 2007 Suzuki XL7. However, it is still accessible from the selected car via links, so may be relevant.

The ECM has the capability of providing command to the fan relays even when a scan tool output control is being used. Always refer to the fan control command parameters on the scan tool to know which fans are being commanded ON by the ECM.

The following tables illustrate the FAN 1 relay, FAN 2 relay and the FAN 3 relay terminal locations in the underhood fuse block:
