Toyota Corolla (E120): On–vehicle inspection
Notice
: ”cold” and ”hot” in these sentences express the temperature of the coils themselves. ”Cold” is from –10 c (14 f) to 50 c (122 f) and ”hot” is from 50 c (122 f) to 100 c (212 f).
1. Inspect ignition coil (with igniter) and spark test
- confirm dtc.
Notice
: if dtc is indicated, carry out troubleshooting in accordance with the procedure on the following dtc.
- check that the spark occurs.
- Remove the ignition coils (with igniter).
- Using a 16 mm (0.63 In) plug wrench, remove the spark plugs.
- Install the spark plugs to each ignition coils (with igniter), and connect the ignition coil connectors.
- Disconnect the 4 injector connectors.
- Ground the spark plugs.
- Check if spark occurs while engine is being cranked.
Notice
:
- be sure to ground the spark plug, when checking.
- Replace the ignition coil when it is given an impact.
- Do not crank the engine for more than 2 seconds.
Hint
: if the spark does not occur, do the test as follow.
- using a 16 mm (0.63 In.) Plug wrench, install the spark plugs.
Torque: 25 nvm (255 Kgf·cm, 18 ft·lbf)
- install the ignition coil with igniter.

Circuit description
The side airbag sensor assy (rh) circuit consists of the diagnosis circuit
and lateral deceleration sensor, etc.
It receives signals from the lateral deceleration sensor, judges whether or not
the srs must be activated,
and detects diagnosis system malfunction.
Dtc b1140/32 is recorded wh ...
Circuit description
The actuator motor is operated by signals from the cruise control ecu assy.
Acceleration and deceleration
signals are transmitted by changes in the duty ratio (see below).
Duty ratio:
the duty ratio is the ratio of the period of continuity in one cycle. For
example, if a is the period of co ...

Inspection procedure
1 Inspect outer ambient temperature sensor
Remove cooler (ambient temp. Sensor) thermistor.
measure resistance between terminals 1 and 2 of cooler
(ambient temp. Sensor) thermistor connector at each temperature.
Resistance:
at 0 c (0 f) ...
