Exhaust gas test for petrol engines without OBD
Note
♦
All test conditions and data necessary for the exhaust gas test:
⇒ "Exhaust gas test"
♦
The ignition point is determined by the Engine control unit -
J623- and will not be indicated. It is not possible to make an
adjustment.
♦
The idle speed rotation and the content of CO cannot be ad‐
justed (just checked). If there are divergences between the
actual and the theoretical values: perform a Repair Measure!
♦
The content of CO is adjusted to the theoretical value by the
lambda probe adjustment. The defects in the lambda probe
inspections are processed by the Diagnosis, Measurement
and Information System -VAS 5051A /52- and stored in the
fault memory.
♦
When consulting the fault memory, the faults detected (elec‐
tronic engine system) must be eliminated and deleted from the
fault memory.
♦
To avoid injuries in people and/or destruction of ignition and
injection systems, the ignition system cables (also high volt‐
age cables) must be turned on and off only with the ignition
turned off.
Note
The following description refers to vehicles without OBD with cat‐
alytic converter adjusted.
Special tools and workshop equipment required
♦ Gas tester - 4 components (CO, CO2, HC and O2) or GAS
TESTER -VAS 6300-
♦ Adapter for older vehicles -VAS 5051/2-
