Actuator Control Cable
INSPECTION PROCEDURE
1 Actuator control cable inspection
OK:
(a) Check that the actuator and control cable throttle link are properly installed and that the cable and link
are connected correctly.
(b) Check that the actuator and bell crank operate smoothly.
(c) Check that the cable is not loose or too tight.
OK:
Freeplay: less than 10 mm
HINT:
If the control cable is very loose, the vehicle's loss of speed going uphill will be large.
If the control cable is too tight, the idle RPM will become high.

PRE±CHECK
1. DIAGNOSIS SYSTEM
(a) Description
ECM controls the function of immobiliser on this vehicle.
Data of the immobiliser or DTC can be read form DLC3 of
the vehicle. When a trouble occurs in immobiliser, MIL
does not light ON but DTC inspection is performed.
Therefore when there seems to be a trouble with immobi-
liser, use TOYOTA hand±held tester or SST to check and
troubleshoot it.
(b) DLC3 INSPECTION
The vehicle's ECM uses ISO 9141±2 for communication.
The terminal arrangement of DLC3 complies with
SAEJ1962 and matches the ISO 9141±2 format.
Tester connectionconditionSpecified condition
7 (Bus Line) ± 5 (Signal ground)During communicationPulse generation
4 (chassis Ground) ± BodyAlways1 W or less
5 (Signal Ground) ± BodyAlways1 W or less
16 (B+) ± BodyAlways9 ± 14 V
HINT:
If your display shows ºUNABLE TO CONNECT TO VEHICLEº
when you have connected the cable of OBD ll scan tool or TOY-
OTA hand±held tester to DLC3, turned the ignition switch ON
and operated the scan tool, there is a problem on the vehicle
side or tool side.
(1) If communication is normal when the tool is con-
nected to another vehicle, inspect DLC3 on the orig-
inal vehicle.
(2) If communication is still impossible when the tool is
connected to another vehicle, the problem is prob-
ably in the tool itself, so consult the Service Depart-
ment listed in the tool's instruction manual.

2. INSPECT DIAGNOSIS
(a) Check the DTC (Using TOYOTA hand±held tester)
(1) Prepare the OBD ll scan tool (complying with SAEJ
1978) or TOYOTA hand±held tester.
(2) Connect the OBD ll scan tool or TOYOTA hand±
held tester to DLC3 under the instrument panel low-
er pad.
(3) Turn the ignition switch ON and turn the OBD ll scan
tool or TOYOTA hand±held tester switch ON.
(4) Use the OBD ll scan tool or TOYOTA hand±held
tester to check the DTCs and freeze frame data;
note them down. (For operating instructions, see
the OBD ll scan tool's instruction book.)
(5) See page DI±924 to confirm the details of the DTCs.
(b) Check the DTC (Using diagnosis check wire)
(1) Turn ignition switch ON.
(2) Using SST, connect between terminals 8 (TE1) and
3 (E1) of DLC1.
SST 09843±18040
(3) Read the diagnostic trouble code from malfunction
indicator lamp.
HINT:
If a diagnostic trouble code is not output, check the Tc ter-
minal circuit .
ECM controls the immobiliser function on this vehicle,
DTC is out put with DTC of engine.
As an example, the blinking patterns for codes; normal, 12 and
99 are as shown in the illustration.

(4) When DTC º99º is output, there is a trouble with
immobiliser. Start troubleshooting referring to
PROBLEM SYMPTOM TABLE.
(5) After completing the check, disconnect terminals 13
(TC) and 4 (CG) and turn OFF the display.
HINT:
In the event of 2 or more malfunction codes. indication will begin
from the smaller numbered code and continue in order to the
larger.
(c) Clear the DTC
The following procedures will erase the DTCs and freeze frame
data.
(1) Operating the OBD ll scam tool (complying with
SAEJ1978) or TOYOTA hand±held tester to erase
the codes. (See the OBD ll scan tool's instruction
book for operating instructions.)
(2) Disconnecting the battery terminals or EFI fuse.

To reduce the unnecessary exchange of ECM, check that a trouble occurs with the original ECM at the time
of exchanging ECM and the trouble will disappear with a new ECM.
