DIAGNOSTIC TROUBLE CODE (DTC) – P1402 ELECTRIC EXHAUST GAS
RECIRCULATION BLOCKED
Circuit Description
An Electric Exhaust Gas Re-circulation (EEGR) system
is used to lower oxides of nitrogen (NOX) emission lev-
els caused by high combustion temperatures. It a ac-
complishes this by feeding small amounts of exhaust
gases back into the combustion chamber. When the air/
fuel mixture is diluted with the exhaust gases, combus-
tion temperatures are reduced.
A EEGR valve is used on this system. The linear EEGR
valve is designed to accurately supply exhaust gases to
the engine without the use of intake manifold vacuum.
The valve controls exhaust flow going into the intake
manifold from the exhaust manifold fhrough an orifice
with a engine control module(ECM) controlled pintle.
The ECM controls the pintle position using inputs from
the Throttle Position (TP) and the Manifold Absolute
Pressure (MAP) sensor. The ECM then commands the
EEGR valve to operate when necessary by controlling
an ignition signal through the ECM. This can be moni-
tored on a scan tool as the Desired EEGR position.
The ECM monitors the results of its command through a
feedback signal. By sending a 5 volt reference and a
ground to the EEGR valve, a voltage signal representing
the EEGR valve pintle position is sent to the ECM. This
feedback signal can also be monitored on a scan tool
and is the actual position of the EEGR pintle. The actual
EEGR position should always be near the commanded
or Desired EEGR position.
ThisDiagnostic Trouble Code(DTC) will detect an open
or short circuit.
Conditions for Setting the DTC

Engine Coolant Temperature(ECT) is greater than
80°C(176°F).
Intake Air Temperature(IAT) is greater than 15°C
(59°F).

Manifold Absolute Pressure is greater than 75kPA.

The EEGR differential rate is less than 3%.

Mass Air Flow is between 92 ~157mg/tdc.

Engine Speed Is Between 2,500~2,900rpm.

EEGR is disabled.
Action Taken When the DTC Sets

The Malfunction Indicator Lamp (MIL) will illuminate.

The ECM will record operating conditions at the time
the diagnostic fails. This information will be stored in
the Freeze Frame and Failure Records buffers.

A history DTC is stored.
Conditions for Clearing the MIL/DTC

The MIL will turn off after four consecutive ignition
cycles in which the diagnostic runs without a fault.

A history DTC will clear after 40 consecutive warm-up
cycles without a fault.

DTC(s) can be cleared by using the scan tool.
Diagnostic Aids
Due to moisture associated with exhaust systems, the
EEGR valve may freeze and stick in cold weather at
times. After the vehicle is brought into a warm shop for
repairs, the valve warms and the problem disappears.
By watching the Actual EEGR and desired EEGR posi-
tions on a cold vehicle with a scan tool, the fault can be

Return Pump Motor
The motor drives two pump elements through the ec-
centric wheel on its shaft.
Return Pump
Description: Each pump element consists of a fixed
displacement piston driven by an eccentric on the end of
the eccentric motor. It has two check valves (inlet and
outlet) and is fed with fluid by the low pressure accumu-
lator.
Operation:
Compression stroke: the pump is filled via the inlet ball
seat, then the motor eccentric rotates moving the piston
to displace the fluid. After the pressure build-up closes
the inlet valve the piston displacement increases the
pressure until the outlet ball opens. The outlet pressure
will continue to increase for the rest of the piston stroke.
Return Stroke: The piston retracts, forced by its spring,
as the motor eccentric returns to its low end position.
The pressure at the inlet side of the outlet ball then de-
creases due to the displaced volume and the pressure
difference across this ball holds it closed.
The pressure at the outlet side of the inlet ball seat,
which is set to open at a certain pressure level also de-
creases until this valve opens. With the outlet ball
closed, the pump is filled with additional fluid from the
low pressure accumulator.
The pressure will continue until a stall point is reached
and compression of the piston cannot generate enough
differential pressure anymore to open the outlet ball
seat.

EBCM (ELECTRONIC BRAKE
CONTROL MODULE)
Notice: There is no serviceable. The EBCM must be re-
placed as an assembly.
The EBCM is attached to the hydraulic unit in the engine
compartment. The controlling element of ABS is a mi-
croprocessor-based EBCM. Inputs to the system in-
clude the four wheel speed sensors, the stoplamp
switch, the ignition switch, and the unswitched battery
voltage. There is an output to a bi-directional serial data
link, located in pin M of the assembly line diagnostic link
(ALDL), for service diagnostic tools and assembly plat
testing.
The EBCM monitors the speed of each wheel. If any
wheel begins to approach lockup and the brake switch is
closed (brake pedal depressed), the EBCM controls the
dump valve to reduce brake pressure to the wheel ap-
proaching lockup. Once the wheel regains traction,
brake pressure is increased until the wheel again begins
to approach lockup. The cycle repeats until either the
vehicle comes to a stop, the brake pedal is released or
no wheels approach lockup.
Additionally, the EBCM monitors itself, each input (ex-
cept the serial data link), and each output for proper op-
eration. If it detects any system malfunction, the EBCM
will store a DTC in nonvolatile memory (DTCs will not
disappear if the battery is disconnected).

5B – 2 FIVE-SPEED MANUAL TRANSAXLE
DAEWOO M-150 BL2
DESCRIPTION AND OPERATION
FIVE-SPEED MANUAL TRANSAXLE
This five-speed transaxle assembly adopts the synchro-
nized mesh type of 5 forward speed. The reverse speed
gear is driven by sliding idle gear without synchronizer.
REVERSE GEAR MISSHIFT
PREVENTING MECHANISM
It prevents the gear from directly being shifted from 5th
to reverse when shifting to reverse from 5th. Shift to the
reverse in neutral position to prevent the shift cam from
being interfered to the shift guide bolt.
D103B001
In case of shifting to 5th gear, shift and select shaft ro-
tates to right that shift cam aparts from guide bolt and
moves upwards by returning spring. Therefore, shifting
to reverse in this condition is impossible because of in-
terference of guide bolt.
D103B002
When shifting to reverse from neutral position between
5th and reverse, shift cam rotates to left and shifting is
possible.
D103B003
DIFFERENTIAL
Differential is integrated with transmission case and
installed on chassis together with engine. It changes the
direction of power and increase torque by reducing
speed.
Reduction gear is installed parallel to counter shaft and
is helical gear type. Differential gear is bevel gear type
and is integrated with reduction gear.
