1.

Electrical systems consist of a lot of harness and connectors, poor connection of terminals can cause various problems and damge of component.

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

a.

Repair the trouble causing part and go to "Verification of Vehicle Repair".

NO

a.

Go to "Signal Circuit Inspection".

1.

Neutral gear switch Voltage Inspection

(1)

IG KEY "OFF", ENGINE "OFF".

(2)

Disconnect neutral gear switch connector.

(3)

Check the voltage of neutral gear switch connector terminal 1.

1)

Secification : 11.5V~13.0V

(4)

Is the measured voltage within the specification?

YES

a.

Go to "Ground Circuit Inspection".

NO

a.

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 Continuity between neutral gear switch connector terminal 1 and ECM connector(CUD-K) terminal 57.

1)

Secification : Approx. below 1Ω

(4)

Is the measured resistance within the specification?

YES

a.

Repair short to ground in signal circuit and go to "Verification of Vehicle Repair".

NO

a.

Repair open in signal circuit and go to "Verification of Vehicle Repair".

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 )

1)

Specification : [TEST "A"] Voltage - [TEST "B"] Voltage = below 200mV

6.

Is the measured voltage within the specification?

YES

a.

Go to "Component Inspection".

NO

a.

When "B" voltage is not detected : Repair open in ground circuit and go to "Verification of Vehicle Repair".

b.

When the voltage difference between "A" and "B" is above 200mV : Eliminate the causes of excessive resistance and go to "Verification of Vehicle Repair".
