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?

	▶ Repair the trouble causing part and go to "Verification of Vehicle Repair".
	▶ Go to "Power Circuit Inspection".

1.

IG KEY "OFF", ENGINE "OFF".

2.

Disconnect Cruise remocon switch connector.

3.

IG KEY "ON".

4.

Measure the voltage of Cruise remocon switch connector terminal 1.

Specification : 4.8V~5.1V

5.

Is the measured voltage within the specification?

	▶ Go to "Signal Circuit Inspection".
	▶ Repair short to ground or open in control circuit and go to "Verification of Vehicle Repair".

1.

IG KEY "OFF", ENGINE "OFF".

2.

Disconnect Cruise remocon switch connector.

3.

IG KEY "ON".

4.

Measure the voltage of Cruise remocon switch connector terminal 2.

Specification : 4.0V~4.2V

5.

Is the measured voltage within the specification?

	▶ Go to "Ground Circuit Inspection".
	▶ Repair short to ground or open in control circuit and go to "Verification of Vehicle Repair".

1.

IG KEY "OFF", ENGINE "OFF".

2.

Disconnect Cruise remocon switch connector.

3.

IG KEY "ON".

4.

Measure the voltage of Cruise remocon switch connector terminal 1. [ TEST "A" ]

5.

Measure the voltage of Cruise remocon switch connector terminal 1 and terminal 3. [ TEST "B" ]

( terminal 1 : Check + prove , terminal 3 : Check - prove )

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

6.

Is the measured voltage within the specification?

▶ Go to "Component Inspection".

▶ 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".
