Auto Repair Manual - How to read codes (No Special Tools Needed)
IMPORTANT:If after you turn the ignition ON no codes are output, then are either NO fault codes OR the vehicle has not been put into diagnostics mode correctly. To test the connection generate a fault code by disconnecting the airflow meter or throttle position sensor, crank or run the engine and re-run the test.

1 Warm the engine and oxygen sensor (if fitted) to operating temperature then switch the engine off.
2 Connect an LED tester or Voltmeter to terminals 'A' & 'B'. (Click here for details)
