Fault text
Throttle valve, adaptation: Marginal conditions not met

Fault description
During the throttle valve adaptation the diagnostic function
monitors compliance with the prescribed process conditions.

Condition for fault identification
Test condition:
Learning routine for lower mechanical travel stop aborted
owing to low battery voltage (< 10 V).
Potential problem source(s):
- Fault code entry is for information only
- Throttle-valve adaptation aborted in response to low
onboard electrical system voltage
Terminal condition: Terminal 15
Voltage condition:
- Onboard electrical system voltage between 9 V and 16 V
Temperature condition:
- Engine warmed to normal temp, above 80 °C
Time condition:
- 30 sec. after Terminal 15 on
Other conditions:
- Engine on
- Vehicle velocity = 0 km/h

Condition for fault memory entry
This fault is logged in the control module's fault memory
immediately.

Action in service
- Check battery voltage (> 10 V), Terminal 15 off ->
Terminal 15 on -> Wait 1 min
- Provided that the voltage condition has been met the fault
should not occur again
- Component replacement based on this fault is not
necessary!

Fault effect and breakdown warning
Breakdown notice:
Ability to continue driving is restricted because engine
speed is limited to roughly 1300 rpm.
Possible apparent symptoms:
- Reduced power
