INSPECTION
1. INSPECT LIGHTING TIME OF GLOW INDICATOR
LIGHT
Turn the ignition switch ON, measure the lighting time.
Light lighting time (T1): Refer to the chart graph
2. INSPECT AFTER GLOW TIME
Turn the ignition switch ON, measure the time battery voltage
is applied to terminal SREL of the preheating timer.
After glow time (T2): Refer to the chart graph
3. INSPECT ENGINE ECU (See page DI--15)
4. INSPECT GLOW PLUG RELAY
(a) Remove the glow plug relay. (Marking: SUB GLW RLY)
(b) Inspect the glow plug relay continuity.
(1) Using an ohmmeter, check that there is no continu-
ity between terminals 1 and 2.
If there is continuity, replace the relay.
(2) Check that there is continuity between terminals 3
and 4.
If there is no continuity, replace the relay.
