2. Disconnect the front combination lamp connectors, rear combination lamp connectors or license plate
lamp connectors.
3. Check continuity between the front combination lamp harness
connector terminal and ground.
4. Check continuity between the license plate lamp harness con-
nector terminal and ground.
5. Check continuity between the rear combination lamp harness
connector terminal and ground.
Does continuity exist?
YES >> Inspect the parking lamp bulb.
NO >> Repair the harness.
WITHOUT DAYTIME LIGHT SYSTEM
WITHOUT DAYTIME LIGHT SYSTEM : DescriptionINFOID:0000000001527574
The IPDM E/R (Intelligent Power Distribution Module Engine Room) controls the tail lamp relay based on
inputs from the BCM via the CAN communication lines. When the tail lamp relay is energized, power flows
through fuse 37, located in the IPDM E/R. Power then flows to the front and rear combination lamps.

2. With test items operating, check that the parking lamp is turned ON.
Is the parking lamp turned ON?

PRECAUTIONS

P
 Use hand tools, power tools (disassembly only) and recommended
special tools where specified for safe and efficient service repairs.
 When repairing the fuel, oil, water, vacuum or exhaust systems,
check all affected lines for leaks.
 Before servicing the vehicle:
Protect fenders, upholstery and carpeting with appropriate covers.
Take caution that keys, buckles or buttons do not scratch paint.
WARNING:
To prevent ECM from storing the diagnostic trouble codes, do not carelessly disconnect the harness
connectors which are related to the engine control system and TCM (transmission control module)
system. The connectors should be disconnected only when working according to the WORK FLOW of
TROUBLE DIAGNOSES in EC and AT sections.
Precaution for Three Way CatalystINFOID:0000000001606119
If a large amount of unburned fuel flows into the catalyst, the catalyst temperature will be excessively high. To
prevent this, follow the instructions.
 Use unleaded gasoline only. Leaded gasoline will seriously damage the three way catalyst.
 When checking for ignition spark or measuring engine compression, make tests quickly and only when nec-
essary.
 Do not run engine when the fuel tank level is low, otherwise the engine may misfire, causing damage to the
catalyst.
Do not place the vehicle on flammable material. Keep flammable material off the exhaust pipe and the three
way catalyst.
Precaution for Fuel (Unleaded Regular Gasoline Recommended)INFOID:0000000001606120
Use unleaded regular gasoline with an octane rating of at least 87 AKI (Anti-Knock Index) number (Research
octane number 91).
CAUTION:
Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Do not use E-85
fuel (85% fuel ethanol, 15% unleaded gasoline) unless the vehicle is specifically designed for E-85 fuel
(i.e. Flexible Fuel Vehicle - FFV models). Using a fuel other than that specified could adversely affect
the emission control devices and systems, and could also affect the warranty coverage validity.

PRECAUTIONS
Precaution for Multiport Fuel Injection System or Engine Control System
INFOID:0000000001606121
 Before connecting or disconnecting any harness connector for the
multiport fuel injection system or ECM:
Turn ignition switch to “OFF” position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.
 Before disconnecting pressurized fuel line from fuel pump to injec-
tors, be sure to release fuel pressure.
 Be careful not to jar components such as ECM and mass air flow
sensor.
Precaution for HosesINFOID:0000000001606122
HOSE REMOVAL AND INSTALLATION
 To prevent damage to rubber hose, do not pry off rubber hose with
tapered tool or screwdriver.
 To reinstall the rubber hose securely, make sure that hose insertion
length and orientation is correct. (If tube is equipped with hose
stopper, insert rubber hose into tube until it butts up against hose
stopper.)
HOSE CLAMPING
 If old rubber hose is re-used, install hose clamp in its original posi-
tion (at the indentation where the old clamp was). If there is a trace
of tube bulging left on the old rubber hose, align rubber hose at
that position.
 Discard old clamps; replace with new ones.

STEP DESCRIPTION
STEP 1Get detailed information about the conditions and the environment when the incident occurred.
The following are key pieces of information required to make a good analysis:
WHATVehicle Model, Engine, Transmission/Transaxle and the System (i.e. Radio).
WHENDate, Time of Day, Weather Conditions, Frequency.
WHERERoad Conditions, Altitude and Traffic Situation.
HOWSystem Symptoms, Operating Conditions (Other Components Interaction).
Service History and if any After Market Accessories have been installed.
STEP 2Operate the system, road test if necessary.
Verify the parameter of the incident.
If the problem cannot be duplicated, refer to “Incident Simulation Tests”.
STEP 3Get the proper diagnosis materials together including:
 Power Supply Routing
 System Operation Descriptions
 Applicable Service Manual Sections
 Check for any Service Bulletins
Identify where to begin diagnosis based upon your knowledge of the system operation and the customer comments.
STEP 4Inspect the system for mechanical binding, loose connectors or wiring damage.
Determine which circuits and components are involved and diagnose using the Power Supply Routing and Harness Lay-
outs.
STEP 5 Repair or replace the incident circuit or component.
STEP 6Operate the system in all modes. Verify the system works properly under all conditions. Make sure you have not inad-
vertently created a new incident during your diagnosis or repair steps.
