The 1995–98 B Series Pick-up models utilize On Board Diagnostic II (OBD-II) Diagnostic Trouble Codes (DTC's), which are alpha-numeric (they use letters and numbers). The letters in the OBD-II DTC's make it highly difficult to convey the codes through the use of anything but a scan tool. Therefore, to read the OBD-II DTC's on these vehicles it is necessary to utilize an OBD-II compatible scan tool.

  1. Ensure that the ignition switch is in the OFF position.
  2. Apply the parking brake.
  3. Ensure that transmission gearshift is in either Park (automatic transmissions) or Neutral (manual transmissions).
  4. Block the rear wheels.
  5. Turn off all electrical loads, such as the heater blower motor, the radio, the rear defroster, etc.
  6. Connect the scan tool to the Data Link Connector. Make certain the test button on the scan tool is unlatched or up.
  7. Turn the ignition switch to the ON position without starting the engine (KOEO).
  8. Using the scan tool, retrieve and record any continuous memory DTC's.
  9. Turn the ignition switch to the OFF position.
  10. Start the engine and run it until normal operating temperature is reached.
  11. Turn the engine OFF and wait 10 seconds.
  12. Turn the ignition switch ON but do not start the engine.
  13. Activate the KOEO self-test. Retrieve and record any KOEO DTC's after the KOEO test is complete.

    NOTE: Ignore DTC 1000.

  14. If any DTC's were present, refer to the accompanying OBD-II charts to locate the problem(s).
