TERMINAL AND CONNECTOR INSPECTION
E26DFBE2
1.
Electrical systems consist of a lot of harness and connectors, poor connection of terminals can cause various prob-
lems and damge of component.
DTC TROUBLESHOOTING PROCEDURES
FL -399
2.
Perform checking procedure as follows.
1)
Check damage of harness and terminals : Check terminals for contact resistance, corrosion and deformation.
2)
Check connecting condition of ECM and component connector : Check terminal seperation, damage of locking
device and connecting condition between terminal and wiring.
NOTE
Disconnect the pin which requires checking at male connector and insert it to the terminal at female connector for
checking connecting condition. ( after checking, reconnect the pin at correct position. )
3.
Is the problem found?
YES
▶
Repair the trouble causing part and go to "Verification of Vehicle Repair".
NO
▶
Go to "Signal Circuit Inspection".
SIGNAL CIRCUIT INSPECTION
EC583E92
1.
Neutral gear switch Voltage Inspection
1)
IG KEY "OFF", ENGINE "OFF"
2)
Disconnect neutral gear switch connector.
3)
IG KEY "ON"
4)
Check the voltage of neutral gear switch connector terminal 1.
Specification : 11.5V~13.0V
5)
Is the measured voltage within the specification?
YES
▶
Go to "Ground Circuit Inspection".
NO
▶
Go to "2. Check open in neutral gear switch signal cicuit" as follows.
2.
Check open in neutral gear switch signal cicuit
1)
IG KEY "OFF", ENGINE "OFF"
2)
Disconnect neutral gear switch connector and ECM connector.
3)
Check the continuity between neutral gear switch connector terminal 1 and ECM connector (C230-K) terminal
57.
specification : Continuity ( below 1.0
Ω
)
4)
Is the continuity test within within the specification?
FL -400
FUEL SYSTEM
YES
▶
Repair short to ground in signal circuit and go to "Verification of Vehicle Repair".
NO
▶
Repair open in signal circuit and go to "Verification of Vehicle Repair".
GROUND CIRCUIT INSPECTION
E56122CD
1.
IG KEY "OFF", ENGINE "OFF"
2.
Disconnect neutral gear switch connector and ECM connector.
3.
IG KEY "ON"
4.
Measure the voltage of neutral gear switch connector terminal 1. [ TEST "A" ]
5.
Measure the voltage between neutral gear switch connector terminal 1 and terminal 2. [ TEST "B" ]
( Terminal 1 : Check + prove , terminal 2 : Check - prove )
Specification : [TEST "A"] Voltage - [TEST "B"] Voltage = below 200mV
6.
Is the measured voltage within the specification?
YES
▶
Go to "Component Inspection".
NO
▶
When "B" voltage is not detected : Repair open in ground circuit and go to "Verification of Vehicle Repair".
▶
When the voltage difference between "A" and "B" is above 200mV : Eliminate the causes of excessive resistance
and go to "Verification of Vehicle Repair".
COMPONENT INSPECTION
E3414D89
1.
IG KEY "OFF", ENGINE "OFF"
2.
Disconnect neutral gear switch connector and ECM connector.
3.
Check the contituity between neutral gear switch component terminal 1 and 2 as shifting gear lever two or three times.
specifications : The measured resistance varies from below 1.0
Ω
(Continuity) to infinite
Ω
(Discontinuity) in accordance with gear shifting.

4.
Is the measured resistance within the specification?
YES
▶
Go to "Verification of Vehicle Repair".
NO
▶
Replace neutral gear switch and go to Verification of Vehicle Repair".
VERIFICATION OF VEHICLE REPAIR
ECB80C0D
After a repair, it is essential to verify that the fault is corrected.
1.
After connecting Scantool select "DIAGNOSTIC TROUBLE CODES(DTCs)" mode.
2.
Clear recorded DTC using Scantool.
3.
Drive the vehicle within DTC "Enable conditions" in "General information".
4.
After selecting "DIAGNOSTIC TROUBLE CODES(DTCs)" mode and check if DTC is recorded again.
5.
Are any DTCs recorded ?
YES
▶
Go to the DTC guide of recorded NO. in Scantool.
NO
▶
System operates within specification.
