Connect the diagnostic unit to the diagnostic connector -1-.
Note
The exhaust gas probe must be fully inserted into the exhaust
tailpipe (do not insert into the suction tube)!
– Start the engine, allow it to warm up to the operating temper‐
ature (the best way is to drive it) and allow it to run in idle.
– Perform the exhaust-emission analysis.
