→ 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 isa fault present which can damage the catalytic converter if the vehicle is driven further with this engine load condition. If the lamp flashes, continue driving only with reduced throttle opening.
-
◆ 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 customer reports a problem or if the engine does not run properly and the exhaust gas warning lamp does not light up. Thisisbecause 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.
