DTC B1422/22 Compressor Lock Sensor Circuit
SYSTEM DESCRIPTION
The ECM sends an engine speed signal to the A/C amplifier via CAN communication and BEAN communication.
The A/C amplifier reads the difference between compressor speed and engine
speed. When the
difference becomes too large, the A/C amplifier determines that the compressor
locks, and turns the
magnetic clutch off.

Power Slide Door LH does not Operate When Using Inside / Outside
Handle
DESCRIPTION
The inside / outside handles have the ability to control operation
of the power slide door. Pulling either
handle transmits a request signal to the power slide door ECU LH, which then
commands the power
slide door control motor and clutch to open / close the power sli ...
