TERMINALS OF ECU

1. CHECK AWD CONTROL ECU

(a) Measure the voltage and resistance of the connector.

Terminal No. (Symbol)	Terminal Description	Condition	Specified Condition
14 (CANH) - 16 (CANL)	CAN communication	Ignition switch off	54 to 69 Ω
23 (GND) - Body ground	Ground	Always	Below 1 Ω
11 (IG1) - 23 (GND)	Power source voltage	Ignition switch ON	10 to 14 V
13 (SLC+) - 32 (SLC-)	Electromagnetic solenoid signal	D position, Idling	Pulse generation (See waveform 1)
9 (BSLC) - 23 (GND)	Power source voltage	Always	10 to 14 V

If the result is not as specified, the AWD control ECU may have a malfunction.

(b) Using an oscilloscope, check the waveform 1.
