Revision: 2007 April2007 M35/M45
Zone Variation Setting ProcedureNKS004F5
NOTE:
The zone setting is factory preset (“default” setting) to zone 8.
1. Press and hold the compass switch for 3 – 9 seconds.
2. The current zone setting appears on the compass display.
3. Find the current geographical location number in the Zone Varia-
tion Chart.
4. Select the new zone number. (Press the compass switch until
the new zone number appears on the compass display.)
5. After select the new zone number, the compass display will
automatically shows a direction within a few seconds.
6. Preform the following Calibration Procedure for more accurate
indications.
Calibration ProcedureNKS004F6
NOTE:
The compass calibrates itself under normal driving conditions. However, occasional circumstances may cause
the compass to operate inaccurately. Example: Driving from rural (wide open) areas to crowded city areas, or
if an aftermarket (i.e., non original equipment) antenna with a magnetic base is attached to the vehicle. Cali-
brate the mirror compass if the display shows only one direction or a limited number of directions.
NOTE:

If “magnetic hats” are used in the dealership for vehicle identification, remove the hat from the vehicle
before performing the following steps. Do NOT put the hat back on the vehicle after the procedure is com-
pleted.

Drive the vehicle to an open level area; away from large metallic objects, structures, and overhead power
lines.

Turn off “non-essential” electrical accessories (rear window defrost, heater/air conditioning, wipers) and
close the doors.
1. Verify the correct compass zone setting for the geographical location. Refer to DI-104, "
Zone Variation
Setting Procedure" .
2. Press and hold the compass switch for more than 9 seconds.
3. “C” is displayed on the compass display, when calibration starts.
4. Drive slowly [less than 8 km/h (5 mph)] in a circle until the “C / CAL” is replaced with primary headings (N,
NE, E, SE, S, SW, W, or NW).
NOTE:
This will require driving at least 2 complete 360 degree circles; 3 complete circles may be required.
5. The compass calibration procedure is now complete. The compass should operate normally.
NOTE:
If at any time the compass continually displays the incorrect direction or the reading is erratic or locked,
repeat the calibration procedure.

BASIC SERVICE PROCEDURE
Revision: 2007 April2007 M35/M45
Accelerator Pedal Released Position LearningNBS004SU
DESCRIPTION
Accelerator Pedal Released Position Learning is an operation to learn the fully released position of the accel-
erator pedal by monitoring the accelerator pedal position sensor output signal. It must be performed each time
harness connector of accelerator pedal position sensor or ECM is disconnected.
OPERATION PROCEDURE

4. Repeat step 2 and 3 for 4 times.
Throttle Valve Closed Position LearningNBS004SV
DESCRIPTION
Throttle Valve Closed Position Learning is an operation to learn the fully closed position of the throttle valve by
monitoring the throttle position sensor output signal. It must be performed each time harness connector of
electric throttle control actuator or ECM is disconnected.
OPERATION PROCEDURE
1. Make sure that accelerator pedal is fully released.
2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds.
Make sure that throttle valve moves during above 10 seconds by confirming the operating sound.
Idle Air Volume LearningNBS004SW
DESCRIPTION
Idle Air Volume Learning is an operation to learn the idle air volume that keeps each engine within the specific
range. It must be performed under any of the following conditions:

Each time electric throttle control actuator or ECM is replaced.

Idle speed or ignition timing is out of specification.
PREPARATION
Before performing Idle Air Volume Learning, make sure that all of the following conditions are satisfied.
Learning will be cancelled if any of the following conditions are missed for even a moment.

Battery voltage: More than 12.9V (At idle)

Engine coolant temperature: 70 - 105°C (158 - 221°F)

PNP switch: ON

Electric load switch: OFF
(Air conditioner, headlamp, rear window defogger)
On vehicles equipped with daytime light systems, if the parking brake is applied before the engine
is started the headlamp will not be illuminated.

Steering wheel: Neutral (Straight-ahead position)

Vehicle speed: Stopped

Transmission: Warmed-up
–With CONSULT-II: Drive vehicle until “ATF TEMP SE 1” in “DATA MONITOR” mode of “A/T” system indi-
cates less than 0.9V.
–Without CONSULT-II: Drive vehicle for 10 minutes.
OPERATION PROCEDURE
With CONSULT-II
1. Perform EC-86, "Accelerator Pedal Released Position Learning" .
2. Perform EC-86, "
Throttle Valve Closed Position Learning" .
3. Start engine and warm it up to normal operating temperature.
4. Check that all items listed under the topic PREPARATION (previously mentioned) are in good order.

CONSULT-II Reference Value in Data MonitorNBS004T9
Remarks:

Specification data are reference values.

Specification data are output/input values which are detected or supplied by the ECM at the connector.
* Specification data may not be directly related to their components signals/values/operations.
i.e. Adjust ignition timing with a timing light before monitoring IGN TIMING, because the monitor may show the specification data in
spite of the ignition timing not being adjusted to the specification data. This IGN TIMING monitors the data calculated by the ECM
according to the signals input from the camshaft position sensor and other ignition timing related sensors.

TROUBLE DIAGNOSIS - SPECIFICATION VALUEPFP:00031
DescriptionNBS004TB
The specification (SP) value indicates the tolerance of the value that is displayed in “DATA MONITOR (SPEC)”
mode of CONSULT-II during normal operation of the Engine Control System. When the value in “DATA MONI-
TOR (SPEC)” mode is within the SP value, the Engine Control System is confirmed OK. When the value in
“DATA MONITOR (SPEC)” mode is NOT within the SP value, the Engine Control System may have one or
more malfunctions.
The SP value is used to detect malfunctions that may affect the Engine Control System, but will not light the
MIL.
The SP value will be displayed for the following three items:

B/FUEL SCHDL (The fuel injection pulse width programmed into ECM prior to any learned on board cor-
rection)

A/F ALPHA-B1/B2 (The mean value of air-fuel ratio feedback correction factor per cycle)

MAS A/F SE-B1 (The signal voltage of the mass air flow sensor)
Testing ConditionNBS004TC

Vehicle driven distance: More than 5,000 km (3,107 miles)

Barometric pressure: 98.3 - 104.3 kPa (1.003 - 1.064 kg/cm2 , 14.25 - 15.12 psi)

Atmospheric temperature: 20 - 30°C (68 - 86°F)

Engine coolant temperature: 75 - 95°C (167 - 203°F)

Transmission: Warmed-up
–After the engine is warmed up to normal operating temperature, drive vehicle until “ATF TEMP SE 1” (A/T
fluid temperature sensor signal) indicates more than 60°C (140°F).

Electrical load: Not applied
–Rear window defogger switch, air conditioner switch, lighting switch are OFF. Steering wheel is straight
ahead.

Engine speed: Idle
