POOR RECEPTION
Is the condition bad in comparison with other vehicle?
Are there any additional installation parts?
(Sun shade film, telephone antenna, etc.)
Check if there is any scratch and breaking of a wire on
the glass antenna and the defogger pattern.
(visual check. tester)
(See page BE-56)
Is the contact of the plug jack of the radio OK?
Does the condition get better by using the outer
antenna (such as pillar antenna)?
Is the contact of the antenna terminal on the glass
surface and the defogger terminal?
Is the continuity of the antenna cord OK?
Check the grounding of the antenna, antenna cord,
choke coil, and noise filter. (See page BE-72)
Does the condition get better by exchanging
the choke coil?
Does the condition get better by exchanging the
antenna cord?Take a measure for contact. An electric wave environment.
Does the condition get better if removing
them?
Influence of additional installation parts.
Influence of the sun shade film.
Repair. (See page BE-56)

4 Check are filter.
PREPARATION:
Remove air filter.
CHECK:
Visually check that the air cleaner element is not dirty or exces-
sively oily.
HINT:
If necessary, clean element with compressed air. First blow from
inside throughly, then blow from outside of element.
NG Repair or replace.
OK
5 Check idle speed.
PREPARATION:
(a) Warm up engine to normal operating temperature.
(b) Switch off all accessories.
(c) Switch off air conditioning.
(d) Shift transmission into ºNº position.
(e) Connect the OBD II scan tool or TOYOTA hand-held tester to DLC3 on the vehicle.
CHECK:
Use CURRENT DATA to check the engine idle speed.
OK:
Idle speed: 650 ± 50 rpm
NG Proceed to matrix chart of problem symptoms
on page DI-169.

DTC P1300 Igniter Circuit Malfunction
CIRCUIT DESCRIPTION
The ECM determines the ignition timing, turns on Tr1 at a predetermined angle (°CA) before the desired
ignition timing and outputs an ignition signal (IGT) º1º to the igniter.
Since the width of the IGT signal is constant, the dwell angle control circuit in the igniter determines the time
the control circuit starts primary current flow to the ignition coil based on the engine rpm and ignition timing
one revolution ago, that is, the time the Tr2 turns on.
When it reaches the ignition timing, the ECM turns Tr1 off and outputs the IGT signal º0º.
This turns Tr2 off, interrupting the primary current flow and generating a high voltage in the secondary coil
which causes the spark plug to spark. Also, by the counter electromotive force generated when the primary
current is interrupted, the igniter sends an ignition confirmation signal (IGF) to the ECM.
The ECM stops fuel injection as a fail safe function when the IGF signal is not input to the ECM.
DTC No.DTC Detecting ConditionTrouble Area
P1300No IGF signal to ECM for 6 consecutive IGT signals during
engine running
Open or short in IGF or IGT circuit from igniter to ECM
