WS5scan tool diagnostics

Make Toyota Model Accord Year 2004
 

Our cause is to used the scan tool to provided us enough information due to engine conditions and as for creating fault codes, we can discuss in group and come to conclusion to fix the problem.

This live data's show normal engine condition before the tutor create a fault in the system.

Type of infoormation PID Parameter Iden	Letters to describe it E.g TPS	Value of      data	Units for    data E.g Volts
Engine Load
Engine RPM	Crank S	91	C
Throttle angle	TPS		Volts
Engine Cooling Temp	ECT	90	C
Intake air temp	IAT	65	C
Fuel Injection (pulse)	FI	2.41	ms
Transmission select P	00	00	00
Vehicle Speed	---	--	--
Oxygen sesor(s)	O2 sensor	0.5	volts
Fuel Trim	Short/Long	1.02/0.99	%
Idle control	Ic	on
Power steering condition
Air conditioning		0.05	volt
Exhaust Gas (EGR)	EGR	no	%
Fuel Evap or puge condi	MIL	yes
Malfunction Indicator Light	BP	8.5	Hz

Trouble Codes or Fault Codes

Here is the list of codes we found on this Engines 

Record any codes and what system and condition they describe in the chart below 

Code number	System affected	Condition described
03 – 02	MAP	High voltage
10 – 02	IAT	High voltage
06 – 02	ECT	Current high input

 Find What Data Has Changed

 This picture shown change in the engine operation TPS is not working.

5.2 Record the PIDs that have changed below:

Type of information (PID = Parameter Identification)	Letters to describe it	Value of data	Units for data
Intake air temperature	IAT	16	C
Throttle position sensor	TPS	0.00	C
Manifold Air pressure	MAP	110	Kpa
Idle Air Control	IAC	1.20	Volts

Visual Inspection to find fault

We found that TPS has been disconnected from its fusible link

Repair fault

We repaired it by plug the sensor back to connector than erase the codes, follow by rechecked the other sensor if were clear from the system.

Recheck Data PIDs

Recheck the data with the scan tool

Record the voltages for the PIDs related to the problem, to confirm they are back to normal

Type of information (PID = Parameter Identification)	Letters to describe it	Value of data	Units for data
MAP Sensor	MAP	102	Kpa
Idle Air Control	IAT	60	C
Engine Coolant	ECT	90	C

Clear Codes

Describe what you did to clear codes:

With the engine on, plug the scan tool to ECU than eraser the code.

Recheck for codes and record codes in system now:

Once the codes is clear than recheck for other codes.

Discuss the importance live data when fault finding

The live data provide detail which used to determine the engine condition, finding codes and used to compare weather this information match specification.

Explain the need for parameters when checking live data

Checking and monitor the engine condition while is running. This live data is use  to compare and make conclusion base on the engine condition, this information is helpful for diagnose problems in the motor vehicle.

Discuss how a scan tool can aid you when fault finding

Very useful equipment to provide codes and other information so we can locate fault components while the engine is operating give us direction were to look for diagnosing.
