Toyota Corolla (E120): Circuit description
Monitor description
The ecm commands gearshift by turning the shift solenoid valves ”on/off”. When there is an open or short circuit in any shift solenoid valve circuit, the ecm detects the problem and the mil comes on. Illuminating the mil, the ecm performs the fail–safe and turns the other shift solenoid valves in good condition ”on/off” (in case of an open or short circuit, the ecm stops sending current to the circuit.).

LDA (Lane Departure Alert)
Basic functions
The LDA system warns the
driver if the vehicle may deviate
from the current lane or course*,
and also can slightly operate the
steering wheel to help avoid
deviation from the lane or
course*.
The front camera is used to
detect lane lines or a course*.

Circuit description
While driving uphill with cruise control activated, in order to minimize gear
shifting and provide smooth cruising
overdrive may be prohibited temporarily under some conditions.
The cruise control ecu sends o/d cut signals to the ecm as necessary and the ecm
cancels overdrive

Disposal
1. Dispose shock absorber assy front lh
fully extend the shock absorber piston rod.
using a drill, make a hole in the cylinder as shown in the
illustration to discharge the gas inside.
Caution:
when drilling, chips may fly out, work carefully.
The gas is colorless, o ...
