Retrieving Codes (Non-Scan)

  1. Before entering on-board diagnostics, refer to SERVICE PRECAUTIONS. Turn ignition switch to OFF position. Locate Data Link Connector (DLC), next to fuse block. Connect voltmeter positive lead to Data Link Connector (DLC) MFI diagnosis terminal and negative lead to ground terminal. See Fig 1 .
  2. Turn ignition switch to ON position. Voltmeter (analog) will display trouble codes by 12-volt pulses of voltmeter needle. Trouble codes are retrieved in numerical order. A constant repetition of short 12-volt pulses indicates system is normal. If system is abnormal, voltmeter will pulse between zero and 12 volts.
  3. Codes will appear on voltmeter as long and short 12-volt pulses. Long pulses represent tens; short pulses represent ones. For example: 4 long pulses and 3 short pulses indicate Code 43. After recording fault code(s), perform necessary repair(s) to indicated circuit(s). See FAULT CODES.
