• If the readiness code was not generated it will need to be re-
generated (the best way to do this is via a test drive or using
the diagnosis device).
• No faults from the exhaust-related systems are stored in event
memory (the warning light for the exhaust system in the in‐
strument cluster does not indicate a fault) – query the event
memory
⇒ “6.9 Connect diagnostic unit and query event memory”,
Caution
♦ 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.
The idling speed, CO content and lambda value are only meas‐
ured and they cannot be adjusted.
The CO content is influenced by the lambda control. Faults in
the Lambda control are indicating by warning light for exhaust
system lighting in the instrument cluster; faults are stored in
event memory.
Resolve all identified faults, including sporadic faults, when
reading the event memory before the exhaust emissions test
(repair
procedure)

Test conditions for vehicles without EOBD
• Faultless function of the engine without extraordinary inequal‐
ities in the engine running behaviour.
• Engine temperature, min. 80 ℃
• Perfect operation of the ignition system
• Intake system tight
• Event memory (01- Engine electronics) is not read
Connect the test equipment to the vehicle
DANGER!
To prevent industrial accidents or avoid causing damage to the
ignition system, pay attention to the following:
♦ Disconnect and connect wires of the ignition system (in‐
cluding high-voltage wires) when the ignition is switched
off.
– Connect the tester in compliance with the operating instruc‐
tions.
