On 2001 vehicles without the diagnostic connector in the engine compartment, the use of
the SIA reset tool is not possible. The service indicator may be reset using the reset mode
in the instrument cluster.
Reset procedure for high and low clusters with SIA III using the Reset Mode:
• Ignition key must be “off”
 Press and hold the trip odometer reset button in the instrument cluster (left button), and
turn the ignition key to the first position.
 Keep the button pressed for approximately 5 seconds until one of the following words
appear in the display: “OIL SERVICE, or “INSPECTION”, with “RESET”.
The service due is shown with “reset” if the coded minimum consumption limit has been
reached and resetting is possible. If “reset” is not shown, the minimum limit has not been
reached and resetting is not possible.

Engines
Two M54 engine variants will be added to the E39 for the 2001 M.Y. starting production
9/00. The M54 B30 and M54 B25. The M54 B30 engine will replace the M52 B28TU of
the 528i and become the 530i. The M54 B25 engine equipped 5 Series will create a new
model, the 525i, it will become the entry level 5 series.
The design objectives for the M54 engine were:
 Lower emissions
 Maintain fuel economy
 Increase power and performance.
The 540i/it will use the A5S 440Z automatic transmission with Steptronic as standard
equipment and continues to have the optional 6 speed manual. The 525i and 530i
models will use the A5S 390R (GM 5) with Steptronic as optional equipment until March of
2001 at which time the GM5 will be replaced by the A5S 325Z (5HP 19).
Please refer to the 2000 Systems Diagnosis course material ST 039 for information concerning the
M54 engine family.

The IHKR control module communicates with the DME via the K-Bus/KOMBI/CAN Bus
link to request permission for compressor activation. The control of the compressor
clutch is directly by the IHKA module via a final stage.
 
Rear Window Defroster:The rear window defroster is controlled via a request from
the button on the panel. After switching on for the first time, the rear window is heated
for 10 minutes. Output voltage to the window is provided by the K13 rear defogger
relay. After automatic switch off, if the button is pressed once again the control unit will
pro vide a clocked operation alternating at 40 seconds on and 80 seconds off. If the
vehicle voltage drops below 11.4V during this second heating operation the function is
stopped, however the LED on the button will not be extinguished. If voltage increases
past 12.2V for at least one second, clocked operation will resume. Clocked operation
continues until the button is pressed again or the ignition is cycled.
Washer Jet Heating:The IHKR provides operating current to the washer jet heaters
based on outside temperature. The washer jets are heated below an outside
temperature of 37
oF.
K-Bus Communication:The IHKR control unit is on the vehicle K-bus and receives
and sends information concerning:
 Engine temperature, RPM, KL61, KL50, compressor request, auxiliary fan request,
compressor load (DME)
 Outside temperature KL15 and road speed (KOMBI)

REST Function
The REST function continues to operate as usual except that the MAX button has taken the
place of the REST button. Activation criteria continues to be:
 Ignition “OFF” or in KL R.
 “MAX” button pressed.
 Outside temperature below 60
o F.
 Coolant temperature above 80o C.
 Battery voltage above 11.4V.
The REST feature operates as previously.
Diagnostics
The IHKA IV diagnosis has been upgraded to the E46 style diagnostic program.
Solar Sensor
The IHKA IV integrates the solar sensor into the
calculation used to automatically regulate the
interior vehicle temperature. The sensor is
located in the right side defrost outlet.
In the case of a very sunny day, the interior
warms faster than the control unit can compen-
sate for. Similar is true if the weather suddenly
becomes overcast.
The input of the solar sensor in the E39 can
affect the operation of:
 Blower setting
 Air distribution to center vent
Because the E39 IHKA IV is a dual zone system. the solar sensor housing contains two
photo-resistors that measure solar radiation on the left and right halves of the interior.
(Please refer to the Solar Sensor module in the 2000
Systems Diagnosis training course ST 039 for a com-
plete description of the solar sensor operation and
diagnosis)
