Diagnostic Test

  1. READ AND RECORD DTCS AND ENVIRONMENTAL DATA - ERASE DTCS AND CHECK FOR DTC TO RETURN 
    NOTE:

    The use of a approved special tool or Digital Multimeter such as a Fluke Meter that will not apply more than 20 milliamperes to a circuit are the only measurement tools to be used.

    NOTE:

    Probing of the circuit cavities at the ORC Module body harness connectors is only to be done with a approved test lead from the Dedicated Test Leads kit 10159, test lead 10159-6. Or a comparable test lead to prevent vehicle wiring harness connector damage during diagnostic procedures. (special tool #10159, Test Leads, Dedicated)

    NOTE:

    Make sure the battery is fully charged.

    1. With the scan tool, read ORC DTCs and record on the repair order.
    2. Record the Environmental Data.
    3. With the scan tool, erase DTCs.
    4. Using the recorded Environmental Data, along with the When Monitored and Set Conditions above, operate the vehicle in the conditions that set the DTC.
    5. With the scan tool, read ORC DTCs.
