A mileage of approximately 33,000 km, the configuration
of this Chevrolet Cruze sedan 1.6L
motor . End users report: car or truck motor fault lights .
Troubleshooting : Connecting bmw icom a2
GDS2 MDI inspection , the engine manage module setup a " current"
mention from the fault codes : P0598, engine coolant thermostat heater command
circuit small voltage.
The motor command module (ECM) controls the
center beat width modulation (PWM) thermostat. Engine coolant heater thermostat
coolant circulation regulate and regulate the engine working temperature. The
motor command module supplies 12V voltage to the heater thermostat . The motor
command module Fgtech is usually a strong condition product called a push
management circuit to ground , to manage the temperature using the motor
coolant heater portion . The generate is provided having a responses circuit
coupled to the voltage . The motor command module displays the feed-back
voltage regulate circuit to ascertain regardless of whether outdoors circuit,
quick to ground or shorter to voltage on.
Engine coolant heater thermostat features a
mechanical failure defense purpose to forestall motor coolant heater thermostat
electrical fault develops . Mechanical thermostat opens at about 104 ℃
when . Mechanical thermostat from 104 cycle to 98. Heater is a component with
the thermostat . Engine tacho
2008 coolant thermostat heater and thermostat housing assembly as a
maintenance.Turn the ignition change during the OFF ( closed ) position ,
disconnect the harness connector E41 engine coolant heater thermostat at amongst
terminals one and Floor bmw icom abc
power circuit have a look at lamp attached to the ignition switch within the ON
placement , success from the test light-weight doesn't shine ; resistance
amongst a K20 engine regulate module wiring harness connector along with the
E41 motor coolant heater thermostat wiring harness connector that includes a
multimeter to evaluate the capability source terminal 35X2 terminal normal, no
short inside ground , indicating the circuit tests are normal , mainly because
failure would be the engine manage module ECM inner failure , wouldn't present
12V voltage for the heater thermostat .
Troubleshooting: Swap the engine management
module ECM, and troubleshooting maintenance programming.
