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 8-72). Replace the
Engine Control
Board
(page 8-106).
