|
Engine switch (push switch) | IPDM E/R (CAN) | Inputs the push-button ignition switch (push switch) signal and transmits the ignition switch status judged with BCM via CAN communication |
Door switch signal | Any door switch |
|
Inputs the door switch signal and transmits it via CAN communication |
Trunk switch signal | Trunk room lamp switch | Combination meter (CAN) | Inputs the trunk room lamp switch signal and transmits the trunk switch signal via CAN communication |
Oil pressure switch signal | IPDM E/R (CAN) | Combination meter (CAN) | Transmits the received oil pressure switch signal via CAN communication |
P1550 battery current sensor
Description
The power generation voltage variable control enables fuel consumption to be
decreased by reducing the
engine load which is caused by the power generation of the generator. The
battery current sensor is installed
to the battery cable at the negative terminal. The sensor measures ...

P0139, P0159 HO2S2
Description
The heated oxygen sensor 2, after three way catalyst (manifold),
monitors the oxygen level in the exhaust gas on each bank.
Even if switching characteristics of the air fuel ratio (A/F) sensor 1
are shifted, the air-fuel ratio is controlled to stoichiometric, by the signal
