start switch input circuit.

 

Disconnect wire from P3. Check for short

 

circuit from this wire to battery positive.

Defective control.

Disconnect wire from P3. Measure voltage from P3 to negative. Voltage should be zero, if not, replace control.

CAUSE OF STATUS INDICATION

This status code will be displayed when P3 is greater than 60% of battery voltage when the key switch is closed.
