W/Harness Inspection

Terminal and connection inspection

1. Many malfunctions in the electrical system are caused by poor harness(es) and terminals. Faults can also be caused by interference from other electrical systems and mechanical or chemical damage.
2. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration or damage.
3. Has a problem been found?






Power Circuit Inspection

Check power circuit voltage
1. IG key OFF.
2. Disconnect 'CRUISE REMOCON SWITCH' connector.
3. IG key ON.
4. Measure voltage between 'CRUISE MAIN' terminal of 'CRUISE REMOCON SWITCH' harness connector and chassis ground.

Specification : 11.5V ~ 13.0V





5. Is the measured value within specification?






Signal Circuit Inspection

Check signal circuit voltage
1. IG key OFF.
2. Disconnect 'CRUISE REMOCON SWITCH' connector.
3. IG key ON.
4. Measure voltage between 'Signal (Cruise SW)' terminal of 'CRUISE REMOCON SWITCH' harness connector and chassis ground.

Specification : 4.8V ~ 5.1V





5. Is the measured value within specification?





Check short in signal circuit
1. IG key OFF.
2. Disconnect 'CRUISE REMOCON SWITCH' connector and ECM connector.
3. Check resistance between 'Signal (Cruise SW)' terminal and 'CRUISE MAIN' terminal of 'CRUISE REMOCON SWITCH' harness connector.
4. Check resistance between 'Signal (Cruise SW)' terminal and 'Ground (Cruise SW)' terminal of 'CRUISE REMOCON SWITCH' harness connector.

Specification : Infinite





5. Is the measured value within specification?





Check open in signal circuit
1. IG key OFF.
2. Disconnect 'CRUISE REMOCON SWITCH' connector and ECM connector.
3. Measure resistance between 'Signal (Cruise SW)' terminal of 'CRUISE REMOCON SWITCH' harness connector and 'Signal (Cruise SW)' terminal of ECM connector.

Specification : Below 1.0 Ohm





4. Is the measured value within specification?
