-
‒ Depress brake pedal and hold.
-
‒ Press accelerator pedal to wide-open position.
- The engine speed is increased by the control unit to
approx. 2 300 rpm.
-
‒ Maintain increased idling speed until the display
in display zone 4 jumps from "Test OFF" to "Test ON". The catalyst temperature in display zone 2 must be at least 350 °C.
Note:
This process can take a few minutes.
-
‒ Maintain the increased engine speed until the display
in display zone 4 shows the specification "B1-P2 OK.
If the display does not indicate as described:
-
‒ Carry out a road test to free Lambda probe of possible residues and repeat the test.
Observe the valid safety precautions when carrying out a road test => Page 24-32.
If the specifications are again not attained:
-
‒ Renew Lambda probe after catalyst (G130).
Note:
If the Lambda probe is renewed, the learnt values in the engine control unit must be erased => Page 24-148
-
‒ Interrogate fault memory, if necessary, repair any faults and then erase fault memory => Page 01-16, interrogating and erasing fault memory.
-
‒ Read-out the readiness code=> Page 01-64.
