Description

USING THE SUPER STAR II TESTER
Vehicles without air suspension is equipped with a stand alone EVO steering control module. This control module is diagnosed using Rotunda Super Star II Tester 007-0041B or equivalent. The test connector used to communicate with the EVO control module is located on the RH side of the luggage compartment.

ENTERING EVO DIAGNOSTICS
^ When the tester is connected, the engine is started and the HOLD/TEST button is latched down, the EVO controller will respond by sending a code 20 to the Star Tester which represents "Diagnostics Mode Entered." If diagnostic trouble code (DTC) 20 is not displayed, go to Pinpoint Test A. A: Steering Diagnostics Can Not Be Entered
^ Once this mode is entered, the EVO control module will continuously cycle through a menu of five tests. The EVO control module will scroll through these tests waiting eight seconds before proceeding to the next test. If at any time in the eight-second period the Star Tester line is toggled high by unlatching the HOLD/TEST button for at least one second but less than eight, then toggled back low by relatching the HOLD/TEST button, the EVO control module will enter and run that selected test. If the HOLD/TEST button is unlatched for the entire eight seconds in between any of the tests, the EVO control module will exit diagnostic mode and resume operation in its normal operating state.
^ If power is removed at any time while the EVO control module is in diagnostic mode, the EVO control module will exit diagnostic mode and resume operation in its normal operating state when power is reapplied.
