INSPECTION
1. INSPECT CLUTCH DISC FOR WEAR OR DAMAGE
Using calipers, measure the rivet head depth.
Minimum rivet depth: 0.3 mm (0.012 in.)
If necessary, replace the clutch disc.
2. INSPECT CLUTCH DISC RUNOUT
Using a dial indicator, check the disc runout.
Maximum runout: 0.8 mm (0.031 in.)
If necessary, replace the clutch disc.
3. INSPECT FLYWHEEL RUNOUT
Using a dial indicator, check the flywheel runout.
Maximum runout: 0.1 mm (0.004 in.)
If necessary, replace the flywheel.
4. INSPECT DIAPHRAGM SPRING FOR WEAR
Using calipers, measure the diaphragm spring for depth and
width of wear.
Maximum:
Depth A: 0.6 mm (0.024 in.)
Width B: 5.0 mm (0.197 in.)
If necessary, replace the clutch cover.

DTC P1300 Igniter Circuit Malfunction No.1
DTC P1310 Igniter Circuit Malfunction No.2
CIRCUIT DESCRIPTION
The ECM determines the ignition timing, turns on Tr1 at a predetermined angle (°CA) before the desired
ignition timing and outputs and ignition signal (IGT) 1 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 O.
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.

± DIAGNOSTICSAUTOMATIC TRANSAXLE (A140E)
625 Author: Date:
The diagnosis system operates in normal mode
during normal vehicle use, and also has a check
mode for technicians to simulate malfunction symp-
toms and perform troubleshooting. Most DTCs use
2 trip detection logic(*) to prevent erroneous detec-
tion. By switching the ECM to check mode when
troubleshooting, the technician can cause the MIL
to light up and for a malfunction that is only detected
once or momentarily.
(TOYOTA hand±held tester) (See page DI±401)
*2 trip detection logic:
When a logic malfunction is first detected, the mal-
function is temporarily stored in the ECM memory.
If the same malfunction is detected again during the
2nd test drive, this 2nd detection causes the MIL to
light up.
(b) Inspect the DLC3.
The vehicle's ECM uses V.P.W. (Variable Pulse Width) for
communication to comply with SAE J1850. The terminal
arrangement of DLC3 complies with SAE J1962 and
matches the V.P.W. format.

5 (Signal Ground) ± BodyAlways1 W or less

HINT:
If your display shows ºUNABLE TO CONNECT TO VEHICLEº
when you have connected the cable of OBD II 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.
If communication is normal when the tool is connected to
another vehicle, inspect DLC3 on the original vehicle.
If communication is still not possible when the tool is con-
nected to another vehicle, the problem is probably in the
tool itself, so consult the Service Department listed in the
tool's instruction manual.
