Basic Inspection
Precaution:
Perform Basic Inspection without electrical or mechanical
loads applied;
lHeadlamp switch is off,
lAir Conditioner switch is off,
lRear defogger switch is off,
lSteering wheel is in the straight-ahead position, etc.
BEFORE STARTING
1. Check service records for any
recent repairs that may indicate a
related problem, or the current need
for scheduled maintenance.
2. Open engine hood and check the
following:
lHarness connectors for faulty con-
nections
lVacuum hoses for splits, kinks, or
faulty connections
lWiring for faulty connections,
pinches, or cuts
3. Using priming pump, bleed air from
fuel system. Refer to ªFuel Filter
Checkº in MA section.
CONNECT CONSULT-II TO THE
VEHICLE.
Connect ªCONSULT-IIº to the data link
connector for CONSULT-II and select
ªENGINEº from the menu. Refer to EC-
CD-27.
DOES ENGINE START?
Ye s
ENo
Turn ignition switch to
the ªLOCKº position, wait
5 seconds and then start
engine. If engine fails to
start, check malfunction
item.
Run engine for 10 minutes.
CHECK IDLE SPEED.
Read engine idle speed in
ªDATA MONITORº mode with
CONSULT-II.
825 rpm   25 (in N position)
---------------------------------------------------------------------------------------------------------------------------------OR---------------------------------------------------------------------------------------------------------------------------------
Check idle speed using tachom-
eter tester.
