Retrieving Codes

1992 Toyota Pickup Base, W55SECTION Retrieving Codes
  1. Before retrieving codes, verify CHECK ENGINE light comes on with ignition on and engine off. The CHECK ENGINE light should go off when engine is started. If CHECK ENGINE light does not come on, see appropriate DIAGNOSTIC CIRCUIT CHECK under CODE CHARTS. If light remains on, system has detected a malfunction or abnormality.
  2. Ensure battery voltage is greater than 11 volts and charging system is okay. Engine should be at normal operating temperature.
  3. Apply parking brake. Shift transaxle to Neutral (M/T) or Park (A/T). Turn A/C and all accessories off. Close throttle valve.
  4. Turn ignition on with engine off. Install jumper wire between terminals TE1 (or T) and E1 in engine check connector. See Fig 1.
  5. Count number of flashes from CHECK ENGINE light. If system is operating properly (with no codes), CHECK ENGINE light will flash continuously and evenly. See Fig 2.
    NOTE: If CHECK ENGINE light will not flash diagnostic codes, see appropriate DIAGNOSTIC CIRCUIT CHECK under CODE CHARTS.
