3.2

 

Intermittent Power

 

 

3.2.1 

Powers on and off constantly

 

 

Check voltage under load. At least 11V must be maintained consistently to operate the radio normally.   

 

If voltage cannot be maintained, load test the battery or power supply.   

 

Check all connections for corrosion, looseness, or other condition that can produce a bad ground.   

 

Check wire harness by wiggling the wire harness on the radio and the vehicle side. If the whole pin comes out, bend 
the holders on the pin so that the pin will stay in the plug (see below image). If the wire comes out of the pin, initiate a 
warranty claim so we can re-pin the radio.   

 

 

 

3.2.2 

Powers off and on while vehicle is moving

   

 

Inspect all connections including the radio’s harness for looseness. Wiggle connections while the radio is operating 
to produce the symptom and narrow down the loose connection. If radio cuts in and out while wiggling the wires on 
the radio side of the wire harness, initiate warranty claim. 

 

3.3 Buttons/controls not responding   

 

Press each button to ensure a click is heard signifying the button is mechanically operational. If one or more buttons 
do not click, initiate a warranty claim.   

 

Disconnect all remotes and extensions from the radio. If the radio works fine, see 

3.11 Erratic Controls

. If the radio 

does not work, initiate a warranty claim if you are under warranty.   

 

See reset option in 

4 Reset Procedure.

 

 

Reset the microprocessor - disengage the radio from power for at least 3 seconds, then reconnect. Both red ACC and 
yellow Memory wires must be disengaged to facilitate a reset of the microprocessor. If both ACC and Memory wires 
are connected to a main breaker or cut-off switch/ignition switch, any of these methods can be used in lieu of 
physically disconnecting the wires.
