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.
Thoroughly check all connectors (and connections) for looseness, bending, corrosion, contamination, deterioration, and/or damage.
Has a problem been found?
YES
Repair as necessary and go to "Verification of Vehicle Repair" procedure
NO
Go to "Charging System Inspection" procedure
Disconnect the battery (+) & (-) terminal cable from the battery, and wait at least one minutes.
Disconnect the SRSCM connector.
Connect the battery negative(-) terminal and turnd the ignition switch ON.
Measure voltage between terminal "23" of the SRSCM harness connector and chassis ground.
Specification : Approx. 10 ~ 16V
Is the measured voltage within specifications?
YES
Go to "Ground circuit inspection" procedure
NO
Check the haness between the battery and SRSC. Check the battery and charging system.
Repair or replace wire harness or related parts if necessary.
Disconnect the battery (+) & (-) terminal cable from the battery, and wait at least one minutes.
Disconnect the SRSCM connector.
Connect the battery negative(-) terminal.
Measure resistance between terminal "49" of the SRSCM harness connector and chassis ground.
Specification : Approx. 1Ω
Is the measured resistance within specifications?
YES
Try to change SRSCM from other vehicle or new part for the test purpose.
If the problem solved go to "Verification vehicle of Repair" procedure
NO
Repair the ground condition.
If the problem solved go to "Verification vehicle of Repair" procedure
Engine "ON", headight and heatwire "ON".
Measure voltage between the battery terminal (+) and (-) maintaining ENG. RPM 2,500RPM (idle) over 2 minutes.
Specification : Approx.10V ~ 16.5V
Is the measured voltage within specifications?
YES
Go to "Power Circuit Inspection" procedure.
NO
Check for fault in charging system and thoroughly check all connectors (and connections) for looseness, bending, corrosion, contamination, deterioration, and/or damage.
Repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure.
