emissions warning lamp in the dashpanel insert does not dis‐
play an error.
• If the readiness code was not generated, it will need to be
generated. The best way to do this is via a test drive or using
the vehicle diagnosis tester. If necessary, check why the sys‐
tem or components has not yet been tested while the vehicle
is moving.
• No fault from the exhaust-related systems is stored in event
memory (the exhaust emissions warning lamp in the dash
panel insert does not indicate a fault) – query the event mem‐
ory ⇒ "6.6 Connect diagnostic unit ", page 160
Caution
♦ A lit exhaust emissions warning lamp in the dash panel
insert indicates an error in the exhaust-related systems.
These faults (including sporadic ones) are stored in event
memory.
♦ The idling speed, CO content and lambda value are only
measured and they cannot be adjusted.
♦ The CO content is influenced by the lambda control. Faults
in the Lambda control are indicated by an exhaust emis‐
sions warning lamp in the dash panel insert; faults are
stored in event memory.
Resolve all identified exhaust-related faults, including sporadic
faults, when reading the event memory, before the exhaust
emissions test
⇒ "6.6 Connect diagnostic unit ", page 160
After deleting the event memory, the readiness code must be
re-generated. The best way to do this is via a test drive or using
the vehicle diagnosis tester.
Test conditions for vehicles without EOBD
• Faultless function of the engine without extraordinary inequal‐
ities in the engine running behaviour.
• Oil temperature at least 80 °C
• 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 Owner's Manual.
Connect the diagnostic unit to the diagnostic connector
