Retrieving Codes

  1. Enter specific test mode by connecting or disconnecting read memory and/or test mode connectors as shown in the RELATIONSHIP BETWEEN MODES & CONNECTORS  table. Connectors are located behind left side of instrument panel. See Fig 1 .
  2. Observe malfunction indicator light (CHECK ENGINE light) or O2 sensor monitor light. Note any trouble codes. Long illumination periods of 1.2 seconds designate tens digit in numbered codes. Short illumination periods of .2 second designate ones digit in numbered codes.
  3. Tens and ones digits are separated by a .3-second interval of non-illumination. For example: 3 long flashes (1.2 seconds each) followed by 5 short flashes (.2 second each) designate code 35.
  4. After a 2-second break, another code will be displayed. Once all existing codes have been displayed, sequence will repeat.
