Idling speed increase via DIS
E38, E39 / M62 with DME 5.2.1
Situation:
In the event of a customer complaint such as the engine snapping at full steering lock or
when pulling away, an effective corrective action is to increase the idling speed. The idling
speed of the M62 with DME control
unit 5.2.1 can be adjusted using the DIS tester.
This Service Information bulletin describes the procedure and the conditions which have to
be satisfied.
Affected
vehicles:
E38 M62, E39 M62 with DME 5.2.1
Manufacturing period: since May 1997 (US models),
since September 1997 (ECE models)
Procedure:
Note:
Due to its adaptation, the engine will run at increased idling speed under the following
conditions:
-
Warming-up phase
-
Low battery voltage
-
The engine runs at idling speed for longer than 450 seconds
-
The air conditioner is switched on
The normal idling speed cannot be adjusted while the engine is running at increased
idling speed! For this reason, the following conditions must always be satisfied when
adjusting the idling speed:
Conditions:
1.
No fault stored in the DME fault memory. If necessary, rectify any fault stored and
clear the fault memory.
2.
Engine at standard operating temperature
(coolant temperature above +85
°
C).
3.
All electrical consumers must be switched off
(air conditioner, headlights, heated rear window, etc.).
4.
Adaptations must be cleared
(DIS: Service functions, 3. Clear adaptation).
To adjust idling speed:
-
Allow the engine to idle (not longer than 7 minutes! If this period is exceeded,
increased idling speed can be returned to normal idling speed by opening the throttle
briefly).
-
DIS program: Digital engine electronics, Service functions,
"Idle-speed adjustment".
-
1st mask: All currently selected idling speeds are displayed. In the event that not all
idling speed values are set with deviation "0 rpm", it must first be checked why
modifications have already been made and whether these are still required.
-
2nd mask: Selection of programmable idling speed states. Depending on idling speed
states, the engine speeds can be adjusted in the following ranges:
