ITEM
No voltage is applied to the fuel pump,
although fuel pump relay is turned ON,
or voltage is applied to fuel pump
although fuel pump relay is turned
OFF.
Voltage is applied to fuel pump
although fuel pump relay is turned
OFF.
No voltage is applied to the fuel pump,
although fuel pump relay is turned ON.
No voltage is applied to the ECM,
although the ignition switch is turned
ON.
No voltage is applied to the speedom-
eter when turning the ignition switch
ON.
Ignition switch signal is not input to the
ECM.
* When the I.D. agreement is not verified.
* ECM does not receive communication
signal from the immobilizer antenna.
HO2 sensor output voltage is not input
to ECM during engine operation and
running condition.
(Sensor voltage < 1.0 V)
In other than the above value, C44
(P0130) is indicated.
The Heater can not operate so that
heater operation voltage is not supply
to the oxygen heater circuit, C44
(P0135) is indicated.
