Troubleshooting Procedure Table
Step Actions and Questions Yes No
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?
Replace any
damaged parts.
Go to Step 2.
2
Clean the CTD (ADC) Sensor.
Does the error persist?
Go to Step 3. Complete
3
Test the CTD (ADC) Sensor.
Run the Service Diagnostics CTD (ADC)
Sensor test.
Does the sensor function correctly?
Go to Step 4. Go to Step 5.
4
Replace the Transfer Roller.
Does the error persist?
Go to Step 5. Complete
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.
Go to Step 6. Replace the FSR/
ADC Harness.
6
Check the CTD (ADC) Sensor signal.
Disconnect P/J136.
Is there 0 V across P136-4 <=> P136-1?
Replace the CTD
(ADC) Sensor
Holder (
page 8-71).
Replace the
Engine Control
Board
(
