Toyota Corolla Repair Manual: Inspection procedure
1 Inspect cruise control actuator assy
- Turn the ignition switch to off.
- disconnect the cruise control actuator assy connector.
- measure the resistance between terminals 1 (mo) and 2 (mc) of cruise control actuator assy.
Hint
: if control plate position is fully opened or fully closed, resistance cannot be measured.
Ok: resistance: more than 4.2 Ω
2 Check harness and connector(between cruise control ecu assy and cruise control actuator assy)
- Check for open and short circuit in harness and connector between cruise control ecu assy and cruise control actuator assy (actuator motor)
Check and replace cruise control ecu assy
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:

Inspection procedure
1 Inspect dlc3 terminal voltage(ts terminal)
Turn the ignition switch to on.
measure voltage between terminals ts and cg of dlc3.
Ok:
voltage: 10 – 14 v
2 Check harness and connector(dlc3 – body ground)
Check for open and short circuit in harness and connector between

Replacement
Hint: components:
1. Table of bolt, screw and nut
Notice:
be sure to tape the tip of the screwdriver when using it to disengage the
meshing of the clips and
claws.
Hint:
indicate the bolts, screws and nuts, which are necessary for installation and
removal of the instrument panel,

Source voltage drop
The srs is equipped with a voltage–increase circuit (dc–dc converter) in the
airbag sensor assy center
in case the source voltage drops.
When the battery voltage drops, the voltage–increase circuit (dc–dc converter)
functions to increase the
voltage of the srs to normal voltage.
The diag ...
