Remove relay from engine compartment fuse/relay box. Using an
ohmmeter, check relay continuity. With battery voltage not supplied to
relay, continuity should exist between terminals No. 1 and 3. With
positive battery terminal connected to relay terminal No. 1 and
negative battery terminal connected to relay terminal No. 3,
continuity should exist between terminals No. 4 and 5. See Fig. 33. If
continuity is not as specified, replace relay.

HAZARD LIGHT SWITCH TEST
Eclipse, Mirage & Montero Sport
Remove hazard light switch from instrument panel. Disconnect
switch connector. Using an ohmmeter, check switch continuity. With
switch in OFF position, continuity should exist between terminals No.
5 and 7, and between terminals No. 9 and 10. With switch in ON
position, continuity should exist between terminals No. 1, 2 and 4,
between terminals No. 5 and 6, and between terminals No. 9 and 10. See
Fig. 34 . If continuity is not as specified, replace switch.

INTRODUCTION
NOTE: Unless stated otherwise in testing procedures, perform all
voltage tests using a Digital Volt-Ohmmeter (DVOM) with a
minimum 10-megohm input impedance. Voltage readings may vary
slightly due to battery condition or charging rate.
Pin voltage charts are supplied to reduce diagnostic time.
Checking pin voltages at the PCM connector determines whether it is
receiving and transmitting proper voltage signals. Diagnostic charts
may also help determine if PCM harness is shorted or open.
TEST PROCEDURE
CAUTION: Shorting positive DVOM lead between connector terminal and
ground could damage vehicle wiring, sensor and PCM.
1) If necessary, remove Powertrain Control Module (PCM) to
access harness connector. For PCM location, see PCM LOCATION table.
Leave PCM connectors connected.
2) Using DVOM, backprobe terminals. Connect positive DVOM
lead to appropriate PCM terminal. Connect negative DVOM lead to PCM
ground terminal. For PCM terminal identification, see appropriate
chart. See Figs. 1-24.
3) All measurements are applicable to vehicle at normal
operating temperature at sea level. Unless otherwise noted, engine is
idling when specification requires engine running. Ensure transmission
shift selector is in Neutral or Park (as applicable). If DVOM displays\
measurement that is not within specification, see G - TESTS W/CODES
article.

INTRODUCTION
Sensor operating range information can help determine if a
sensor is out of calibration. An out-of-calibration sensor may not set
a diagnostic trouble code, but it may cause driveability problems. For
sensors not listed in this article, see G - TESTS W/CODES article.
NOTE: Unless stated otherwise in test procedure, perform all
voltage tests using a Digital Volt-Ohmmeter (DVOM) with a
minimum 10-megohm input impedance. For connector terminal
identification, see TERMINAL IDENTIFICATION in

INTRODUCTION
This article contains underhood views or schematics of vacuum
hose routing. Use these vacuum diagrams during the visual inspection
in F - BASIC TESTING article. This will assist in identifying
improperly routed vacuum hoses, which cause driveability and/or
computer-indicated malfunctions.
NOTE: California and Federal applies to installed emission
equipment, which may be verified by underhood Emission
Control label. California emissions may be available in
other states.
NOTE: Always refer to Emission Control label in engine compartment
before attempting service. If manual and label differ,
always use emission label specifications.

MAINTENANCE SERVICE INFORMATION
SEVERE & NORMAL SERVICE DEFINITIONS
Service is recommended at mileage intervals based on vehicle
operation. Service schedules are based on the following primary
operating conditions.
Normal Service
* Driven More Than 10 Miles Daily
* No Operating Conditions From Severe Service Schedule
Severe Service (Unique Driving Conditions)
NOTE: Use the Severe Service schedule if the vehicle to be serviced
is operated under ANY (one or more) of these conditions:
* Driving In Dusty Conditions
* Towing A Trailer, Police, Taxi, Or Commercial Type Operation
* Extensive Idling, Driving In Stop And Go Traffic
* Short-Trip Operation At Freezing Temperatures
(Engine Not Thoroughly Warmed Up)
* Driving In Sandy Areas
* Driving In Salty Areas
* More Than 50% Operation In Heavy City Traffic Or At Sustained
High Speeds During Hot Weather Above 90
\bF (32\bC)
* Driving On Off-Road
CAMSHAFT TIMING BELT
Replace the camshaft timing belt every 60,000 miles. It is
recommended that the timing belt be inspected every 30,000 miles after
replacement.
CAUTION: Failure to replace a faulty camshaft timing belt may result
in serious engine damage.
The condition of camshaft drive belts should always be
checked on vehicles which have more than 50,000 miles. Although some
manufacturers do not recommend belt replacement at a specified
mileage, others require it at 60,000-100,000 miles. A camshaft drive
belt failure may cause extensive damage to internal engine components
on most engines, although some designs do not allow piston-to-valve
contact. These designs are often called "Free Wheeling".
Many manufacturers changed their maintenance and warranty

WHEEL & TIRE SPECIFICATIONS
Tire specifications are imprinted on the tire side wall. The
recommended cold tire inflation pressures are listed on a label
attached to the rear face of the driver's door. These pressures
provide the best combination of ride comfort, tire wear and stability
under normal conditions.
CAUTION: DO NOT mix tires of different design such as radial ply
with bias or bias-belted tires. Mixing tire types will
adversely affect road handling and may lead to loss of
vehicle control. When using snow tires, they must be used
in set of four for maneuverability and safety. DO NOT use
tire chains on front wheels.
