Freeze Frame Data
FREEZE FRAME DATA DESCRIPTION (a) Whenever a forward recognition camera system DTC is stored, the forward recognition camera stores the current vehicle state (ECU and sensor information) as Freeze Frame Data. CHECK FREEZE FRAME DATA (a) Connect the Techstream to the DLC3. (b) Turn the ignit ...

Meter Illumination is Always Dark
DESCRIPTION In this circuit, the combination meter assembly receives auto dimmer signals from the main body ECU (multiplex network body ECU) using the CAN communication system (CAN V1 Bus). When the meter CPU receives an auto dimmer signal, it dims the meter illumination (warning and indicato ...

Pressure Sensor Circuit (B1423/23)
DESCRIPTION This DTC is stored if refrigerant pressure on the high pressure side is extremely low (176 kPa (1.8 kgf/cm2, 26 psi) or less) or extremely high (3140 kPa (32.0 kgf/cm2, 455 psi) or more). The air conditioner pressure sensor, which is installed on the pipe on the high pressure side ...
