→ Location of exhaust emissions warning lamp
Note:
The exhaust emissions warning lamp can switch on in the continuous or flashing mode. Always interrogate fault memory .
-
◆ Flashing mode: There is a faultpresent which can damage the catalytic converter if the vehicle is driven further in this condition (with the same throttle opening). If this occurs, continue driving only at reduced power.
-
◆ Continuous mode: There is a fault present which causes the emissions to deteriorate. Interrogate engine or gearbox control unit in this case.
-
◆ Interrogate the fault memory if the engine doesnot run properly or if the customer has reported a problem and the exhaust gas warning lamp does notlight up. This is because faults can be stored which will not switch the exhaust gas warning lamp on immediately.
Functional check:
-
‒ Switch on ignition:
the exhaust emissions warning lamp must light-up.
If the exhaust emissions warning lamp does not light-up with ignition switched on:
If the exhaust emissions warning lamp lights-up with ignition switched on, continue check as follows:
-
‒ Start engine and run at idling speed:
The exhaust emissions warning lamp must go out after a few seconds.
If the exhaust emissions warning lamp does not go out:
-
‒ Interrogate fault memory, if necessary, repair any faults and then erase fault memory => Page 01-19, interrogating and erasing fault memory.
