IGNITION TIMING INSPECTION AND
ADJUSTMENT
(2JZ±GE)
1. WARM UP ENGINE
Allow the engine to warm up to normal operating tempera-
ture.
2. CONNECT TACHOMETER AND TIMING LIGHT
Connect the tester probe of a tachometer to terminal IG of
the DLC1.
NOTICE:
wNever allow the tachometer terminal to touch ground as it
could result in damage to the Igniter and/or ignition coil.
wAs some tachometers are not compatible with this ignition
system, we recommend that you confirm the compatibility
of your unit before use.
