IGNITION TIMING
INSPECTION
1. WARM UP ENGINE
Allow the engine to warm up to normal operating temperature.
2. INSPECT IGNITION TIMING
(a) When using a hand±held tester.
(1) Connect a hand±held tester to the Controller Area
Network Vehicle Interface Module (CAN VIM). Then
connect the CAN VIM to the Date Link Connector 3
(DLC3).
(2) Please refer to the hand±held tester operator's
manual for further details.
Ignition timing: 5 to 15° BTDC at idle
(Transmission in neutral)
(3) Disconnect the hand±held tester and CAN VIM
from the DLC3.
(b) When not using a hand±held tester.
(1) Connect the tester probe of a timing light to the wire
(black ± red) of the ignition coil connector for the
No.1 cylinder.
(2) Using SST, connect terminals TC and CG of the
DLC3.

2. INSPECT ENGINE IDLE SPEED
(a) When using a hand±held tester.
(1) Connect a hand±held tester to the Controller Area
Network Vehicle Interface Module (CAN VIM). Then
connect the CAN VIM to the Date Link Connector 3
(DLC3).
(2) Please refer to the hand±held tester operator's
manual for further details.
(3) Race the engine speed at 2,500 rpm for approx. 90
seconds.
(4) Check the idle speed.
Idle speed: 700 ± 50 rpm
(Transmission in neutral)
If the idle speed is not as specified, check the air intake system.
(5) Disconnect the hand±held tester and CAN VIM
from the DLC3.
(b) When not using a hand±held tester.
(1) Using SST, connect the tachometer probe to termi-
nal TAC of the DLC3.
SST 09843±18030
(2) Race the engine at 2,500 rpm for approx. 90 se-
conds.
(3) Check the idle speed.
Idle speed: 700 ± 50 rpm
(Transmission in neutral )
If the idle speed is not as specified, check the air intake system.
