There are 2 connectors under the dash taped above the steering column; black,which is Read Mode & green, which is Test Mode; they are both pairs both male & female.
With both the green & black connectors disconnected turn the ignition key ON without the engine running. Observe the CHECK ENGINE light on the dash. It will flash in a certain sequence; starting with a long flash or a number of long flashes, which represent the first digit of the code. The Check Engine light will then flash a series of short flashes, which represent the second digit. For example four long flashes will represent the first digit, 4, followed by two short flashes representing the second digit 2, giving you code 42. There maybe several codes stored so you need to watch the sequence closely. Write the trouble codes down on a pad as you observe them & double check them.
The easiest way to clear the trouble codes once you have retrieved them is to disconnect the battery negative terminal for 30 seconds.
Code 11 Crank angle sensor/circuit No reference pulse.
Code 12 Starter switch Starter switch remains in ON or OFF position.
Code 13 Cam angle sensor No position pulse.
Code 14 Fuel injector #1 Abnormal injector output.
Code 15 Fuel injector #2 Abnormal injector output.
Code 16 Fuel injector #3 Abnormal injector output.
Code 17 Fuel injector #4 Abnormal injector output.
Code 21 Coolant temp sensor Sensor circuit or sensor malfunctioning.
Code 22 Knock sensor Open or shorted knock sensor circuit.
Code 23 Airflow sensor Open or shorted airflow sensor circuit.
Code 24 Air control valve Open or shorted air control valve circuit.
Code 31 Throttle position sensor TPS sensor circuit open or shorted.
Code 32 Oxygen sensor Oxygen sensor circuit is open.
Code 33 Vehicle speed sensor No speed sensor signal during operation.
Code 35 Purge control solenoid valve Purge control solenoid remains in the ON or OFF position during operation.
Code 41 Fuel mixture LEAN Computer detects LEAN air/fuel ratio.
Code 42 Idle switch Idle switch signal incorrect.
Code 44 Wastegate control solenoid Wastegate solenoid valve.
Code 45 Atmospheric sensor Faulty atmospheric pressure sensor or pressure exchange solenoid.
Code 49 Airflow sensor Use of incorrect airflow sensor.
Code 51 Neutral switch Neutral switch remains in the ON position during operation (manual transaxle).
Code 51 Inhibitor switch Inhibitor switch remains in the ON position during operation (auto transaxle).
Code 52 Parking switch Parking switch remains in the ON position during operation.
Here is a description of two further tests that can be carried out to extract codes, these checks are normally done by the service department.
Read Memory Mode - for checking stored fault codes that detect past problems. Black connector connected, green connector disconnected, ignition ON.
D-Check Mode - for checking faulty parts. Black connector disconnected, green connector connected, engine idling.
You will also need a good digital multimeter for checking individual components.
Hope this will be of some help.
Hey My friend... thanks i really appreciate.. this info will be work.... now im going to try with my Vivio...
