1. Once all connections have been checked, energize the system.A) The RED indicator light should come on. This indicates that the control is 'OFF'.*... If the LO indicator light is 'ON', it indicates an open connection on the BLUE output wire going to the center solenoid.... If the MED indicator light is 'ON', it indicates an open connection on the YELLOW output wire going to the front and/or rear solenoids*If the RED light starts to flash: This indicates that there is an open connection on the output.If an open connection occurs, insure that there is a good connection at the solenoid, and at the output of the control module. If there is still a problem remove the harness connections on the 002299 terminal leadout. Measure the resistance of the solenoid at the 002299 terminal leadout on the Jake Brake housing (+ probe on the 002299 terminal, - probe to ground). The ohmmeter should read between 7 and 14 ohms. If it does not, replace the solenoid. If the problem still occurs, replace the suspected output wire, and insure a good connection
