Basic Inspection
Precaution:
Perform Basic Inspection without electrical or mechanical
loads applied;
IHeadlamp switch is OFF,
IAir conditioner switch is OFF,
IRear defogger switch is OFF,
ISteering 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 fol-
lowing:
IHarness connectors for improper con-
nections
IVacuum hoses for splits, kinks, or
improper connections
IWiring for improper 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.
DOES ENGINE START?
Ye s
ENo
Turn ignition switch to
ªLOCKº position, wait 5
seconds and then start
engine. If engine fails to
start, check diagnostic
trouble code (DTC).
Run engine for 10 minutes.
CHECK IDLE SPEED.
Read engine idle speed in ªDATA
MONITORº mode with CONSULT-II.
725 rpm  50 (in N position)
------------------------------------------------------------------------------------------------------------------------------------OR------------------------------------------------------------------------------------------------------------------------------------
Check idle speed using tachometer
tester.
