– Pull 4-pin connector off coolant temperature sender - G62-

with coolant temperature sender - G2- -1-.

The control unit must recognise the disturbance variable and

eliminate through regulation within 60 seconds.

Note

The throttle valve must not be operated during the test, otherwise

the disconnected connector will be recognised as fault by the self-

diagnosis and stored in the fault memory.

– Deactivate the disturbance variable as follows:

– Fit connector to coolant temperature sender.

Note

When connecting the connector always ensure that it is fitted

properly and engages noticeably.

The control unit must recognise deactivation of the disturbance

variable and eliminate through regulation within 60 seconds.

♦ The disturbance variable has been recognised only in one di‐

rection.

♦ The control circuit test is also completed when the disturbance

variable has been recognised only in one direction.

♦ Continue test sequence by pressing the F1 button.

If actual figures deviate from specifications: Carry out repair

measures and again perform exhaust emissions test!

Note

♦ The test data can be printed out by pressing the F3 button.

♦ It is possible to carry out an exhaust emissions test only when

all units of the exhaust emissions station are connected prop‐

erly and joined to each other according to the operating in‐

structions.

♦ All work to be performed is displayed by the exhaust emissions

station .

values for exhaust emissions test” on display as follows:

1 - Test speed (idling speed)

2 - Warm-up phase for catalytic converter

3 - Engine temperature

4 - Increased idling speed

5 - CO content at increased idling speed

6 - Lambda at increased idling speed
