Terminals of ecmCompressor lock sensor circuit
Description
This sensor sends 1 pulse per engine revolution to the air conditioning
amplifier. If the ratio of the
compressor speed divided by the engine speed is smaller than a predetermined
value, the air conditioning
amplifier turns the compressor off, and the indicator blinks at appro ...
Check mode procedure
Hint:
Intelligent tester only:
compared to normal mode, check mode is more sensitive to
malfunctions. Therefore, check mode can detect the
malfunctions that cannot be detected by normal mode.
Notice:
All the stored dtcs and freeze frame data are erased if:
The ecm is changed from normal mo ...
Low battery positive voltage
Description
When there is an abnormality in the power supply circuit of the brake
actuator (skid control ecu), the skid
control ecu sets a dtc and the operation is prohibited by the fail-safe
function. This dtc is set when the
voltage supplied to terminal ig1 is outside the dtc detection ...
