NO
Go to "Charging System Inspection" procedure
Disconnect negative(-)terminal cable from the battery than wait more than 30sec for the safety reason.
Disconnect the SRSCM connector.
Connect the battery negative(-) terminal and turnd the ignition switch ON.
Measure the voltage between the terminal 11 of the SRS connector and body 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 negative(-)terminal cable from the battery than wait more than 30sec for the safety reason.
Disconnect the SRSCM connector.
Connect the battery negative(-) terminal.
Measure the resistance between the terminal 12 and 23 of the SRS connector and body 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 of Vehicle Repair" procedure
NO
Repair the ground condition.
If the problem solved go to "Verification of Vehicle Repair" procedure
Ignition "ON"& Engine "ON", headight and heater ON.
Measure voltage between terminal (+) and (-) of battery while maintaining ENG. RPM in idle to 2,500RPM over the 2 minute.
Specification : Approx.10V ~ 16.5V
Is the measured voltage within specifications?
YES
Go to "Power circuit inspection" procedure.
NO
Check tension of alternator drive belt, ENG.idle rpm, poor connection of fuse and harness from battery to alternator.
☞ Repair charging system as necessary and then go to "Verification of Vehicle Repair" procedure.
