Weight Classification
B1112 Ignition Voltage Low - Inspection/Repair:_:W/Harness Inspection

Terminal and Connector Inspection

1. Many malfunctions in the electrical system are caused by poor harness 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?






Charging System Inspection

1. Engine "ON", headight and heatwire "ON".
2. Measure voltage between the battery terminal (+) and (-) maintaining ENG. RPM 2,500RPM (idle) over 2 minutes.

Specification :Approx. 9 ≤ Vbatt ≤ 16




3. Is the measured voltage within specifications?






Power Circuit Inspection

1. Ignition "OFF'.
2. Disconnect the battery (-) terminal cable from the battery, and wait at least one minutes.
3. Disconnect the WCS ECU connector.
4. Connect the battery (-) terminal cable and start engine.
5. Measure voltage between power terminal of the WCS harness connector and chassis ground.

Specification :Approx. 9 ≤ Vbatt ≤ 16




6. Is the measured voltage within specifications?






WCS Reset

1. Ignition "OFF", connect scantool.
2. Ignition "ON"& Engine "OFF", select Weight Classification System and select "WCS Reset" mode.
3. You will see comments and current weight measured.
4. Make sure the measure weight is caused by occupant or tools or interference.
5. And then press "ENTER"
