2 Check voltage between terminal +B2 (B) of ECU connector and body ground.
PREPARATION:
Disconnect the theft deterrent and door lock ECU connector.
CHECK:
Measure voltage between terminal +B2 (B) of ECU connector
and body ground.

IGNITION TIMING
INSPECTION
1. WARM UP ENGINE
Allow the engine to warm up to normal operating temperature.
2. CONNECT TOYOTA HAND-HELD TESTER OR OBDII
SCAN TOOL
(a) Remove the fuse cover on the instrument panel.
(b) Connect the TOYOTA hand-held tester or OBDII scan
tool to the DLC3.
(c) Please refer to the TOYOTA hand-held tester or OBDII
scan tool operator's manual for further details.
3. CONNECT TIMING LIGHT
4. INSPECT IGNITION TIMING
(a) Using SST, connect terminals TE1 and E1 of the DLC1.
SST 09843-18020
(b) Using a timing light, check the ignition timing.
Ignition timing:
10° BTDC @ idle
(w/ Cooling fan OFF and transmission in neutral
position)
(c) Remove the SST from the DLC1.
SST 09843-18020
5. FURTHER CHECK IGNITION TIMING
Check that the ignition timing advances.
Ignition timing:
7 - 17° BTDC @ idle
(w/ Cooling fan OFF and transmission in neutral posi-
tion)
HINT:
The timing mark moves in a range between 7° and 17°.
6. DISCONNECT TIMING LIGHT

(f) Check that there are no fuel leaks after performing main-
tenance anywhere on the fuel system.
(1) Remove the fuse cover on the instrument panel.
(2) Connect the TOYOTA hand- held tester to the
DLC3.
(3) Turn the ignition switch ON and TOYOTA hand-
held tester main switch ON.
NOTICE:
Do not start the engine.
(4) Select the active test mode on the TOYOTA hand-
held tester.
(5) Please refer to the TOYOTA hand-held tester oper-
ator 's manual for further details.
If you have no TOYOTA hand-held tester, connect the positive
(+) and negative (-) leads from the battery to the fuel pump con-
nector (See page MF-5).
(6) Pinch the fuel return hose.
(7) The pressure in the high pressure line will rise to
approx. 392 kPa (4 kgf/cm
2, 57 psi). In this state.
Check to see that there are no leaks from any part
of the fuel system.
NOTICE:
Always pinch the hose. Avoid bending as it may cause the
hose to crack.
(8) Turn the ignition switch to LOCK.
(9) Disconnct the TOYOTA hand-held tester from the
DLC3.
(10) Install the fuse cover on the instrument panel.
