Troubleshooting Procedure Table
Step Actions and Questions
1 Check the following for evidence of fault or
damage:
Transfer Roller, PL5.1.4
CTD (ADC) Sensor Holder,
PL5.2.19
Are any parts damaged?
2
Clean the CTD (ADC) Sensor.
Does the error persist?
3 Test the CTD (ADC) Sensor.
Run the Service Diagnostics CTD (ADC)
Sensor test.
Does the sensor function correctly?
4
Replace the Transfer Roller.
Does the error persist?
5 Check all pins on the FSR/ADC Harness
PL5.2.28 for continuity.
1. Disconnect P/J36 and P/J136.
2. Check continuity between J36 <=> J136.
6
Check the CTD (ADC) Sensor signal.
Disconnect P/J136.
Is there 0 V across P136-4 <=> P136-1?
