1. 1

   Check if the EEV connector is correctly and firmly inserted into the PCB.

2. 2

   Turn the power off and then back on.

3. 3

   Listen for a repositioning sound from the EEV approximately 2 minutes after power-on. If no sound is heard, proceed to the next step.

4. 4

   Disconnect the EEV connector and check its resistance against the resistance tables in the manual.

5. 5

   If resistance is okay, the PCB may be at fault and require replacement.
