Today I repaired a Chevrolet Cruze with
33,000 miles on there. The automobile was furnished with a single.6L engine. And its particular check engine
light was always on in last two days.
Sometimes, an illuminated check engine
light problem is actually a small issue. Sometimes, it might talk about a
significant one. To look for the problem, I connected the engine control module
using a GM
Tech 2, and served a fault code: P0598. The error code described “Thermostat
Heater Control Circuit Low”.
Thermostat heater features anti mechanical
failure function to stop the heater from electrical accident. Usually the
thermostat is going to be active in a temperature at 104 Celsius. As heater can
be a indispensible component of thermostat, I often repair them being an
Initially when i first switched off the
lock, disconnected cable connector of E41 thermostat heater so started up the
ignition lock to try connection between 1st power circuit terminal and its bonding.
There was clearly the light source relating to the terminal and its particular
bonding. Should the connection was alright, the light would illuminate.
However, it did not.
I quickly used a MST-2800B multi-meter to
evaluate 35X2 power circuit terminal of K20 engine control module and the 1st
terminal of cable connector of E41 engine thermostat heater. In line with the
multi-meter, the resistance involving the two terminals was normal. This
indicated the circuit together was normal, and also the problem was likely
inside the engine control module, which failed to provide 12V voltage to
I replaced the ECM, tested the Chevrolet,
along with the check engine light would stop then
