Procédure lire les codes défauts sur un 3.0l sans le consult

[Papy Mouzo]

Voilà une prcédure qui est fort utile quand on a un voyant diag allumé dans le désert, et qu'on ne sait pas d'ùu ça vient ( désolé, c'est en Anglais.. ) :

 

 

Displaying the ECU fault codes. (ZD30) 3.0ltr TDi

 

1.Ensure that the battery is fully charged and that the engine is at normal operating temperature.

 

2.Ensure all accessories are switched off.

 

3.Switch the ignition On but do not start the engine.

 

4.Bridge terminals 8 (IGN) and 1 (CHK) on the diagnosis connector. The engine waring lamp should extinguish.

 

Connector diagram (looking front on) it looks like a wiring plug rectangle shape.

 

Top row

16,15,14,13,12,11,10,9

8,7,6,5,4,3,2,1

Bottom row

 

Bridging 8 (IGN) and 1 (CHK) with piece of wire (just push it into the slot)

 

5.Wait at least 2 seconds and then remove the wire bridging the terminals of the diagnosis connector. Any stored fault codes should now be able to be read.

 

6.Read the codes by counting the number of flashes of the Check Engine warning lamp. The code numbers are displayed as sets of separated by a 2.1 second pause. Each set comprises a series of 0.6 second flashes, a 0.9 second pause and a further series of 0.3 second flashes. The first set represents the first 2 digits of the code and the second set represents the last 2 digits.

 

Example 1. Code 0102 (Air Flow sensor) would be shown as one 0.6 second flash, a 0.9 second pause and two 0.3 second flashes.

 

Example 2. Code 1004 (Injection Pump fuel cut out system) would be shown as ten 0.6 second flashes, a 0.9 second pause and four 0.3 second flashes.

 

Note: To cease retrieving codes or to read codes again, turn the ignition Off and wait at least ten seconds before restarting the above procedure if necessary.

-----------------------------------------------------

Clearing Fault Codes:

 

1.After reading the fault codes as described, reconnect the wire bridging terminals 8 (IGN) and 1 (CHK) while the ignition is still On.

 

2.Wait at least two seconds and then remove the wire bridging the terminals. Any stored codes should now be erased.

 

Note: Fault codes are also erased if the battery is disconnected for more than 24 hours.

 

3.Road test the vehicle and check that there are no fault codes stored.
