Note
♦
The lit warning light for exhaust system in the dash panel insert
indicates faults in the exhaust-relevant systems. These faults
(including sporadic ones) are stored in event memory.
♦
Resolve all identified faults, including sporadic faults, when
reading the event memory before the exhaust emissions test
(repair procedure)
⇒ “6.9 Connect diagnostic unit and query event memory”,
.
Test conditions for vehicles without EOBD
• Faultless function of the engine without extraordinary inequal‐
ities in the engine running behaviour.
• Engine temperature, min. 80 ℃
• Air conditioning switched off
• Event memory (01- Engine electronics) is not read
Connect the test equipment
– Connect the tester in compliance with the operating instruc‐
tions.
– 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.
Note
♦
All tubes and plug connections, which had been removed or
disconnected for the test and adjustment, must be correctly
re-inserted or connected.
♦
The exhaust gas probe must be fully inserted into the exhaust
tailpipe (do not insert into the suction tube)!
