TERMINALS OF ECM
CHECK ECM
HINT:
The standard normal voltage between each pair of ECM terminals is shown in the table below. The appropriate conditions for checking each pair of terminals are also indicated. The result of checks should be compared with the standard normal voltage for that pair of terminals, displayed in the Specified Condition column. The illustration above can be used as a reference to identify the ECM terminal locations.

Toyota CH-R Service Manual > Airbag System: Front Airbag Sensor LH Malfunction (B1615/14)
DESCRIPTION
The front airbag sensor LH circuit consists of the airbag sensor assembly and
front airbag sensor LH.
The front airbag sensor LH detects impacts to the vehicle and sends signals to
the airbag sensor assembly to determine if the airbags and pretensioners should
be deployed.

Toyota CH-R Service Manual > Continuously Variable Transaxle System: Shift Solenoid "G" Control Circuit Low (Shift Solenoid Valve SC) (P099B,P099C)
DESCRIPTION
Based on the signal received by the shift solenoid valve SC, the ECM uses the
shift solenoid valve SLU to control the forward and reverse clutch pressure.
If there is an open or short in the shift solenoid valve SC circuit, the ECM
stops sending current to the defective shift solen ...
