The selected gain for ADC was out of range.
Initial Actions
• Refer to BSD 9.8 and BSD 9.15 for the following procedure.
• Clean the ADC Sensor.
• Clean the IBT Belt.
• Check that the P/J139 on t
he ADC Sensor PWB, IBT connector J702A, J702B and P/
J416A on the IOT Drive PWB are firmly connected.
Procedure
Go to Flag 7 and Flag 8 on BSD 9.8. Check the wires for an open circuit or a short circuit. If the
wires are good, replace the ADC Sensor (PL 7.5). If the problem continues, replace the IOT
