Diagnostic Procedure

STEP	INSPECTION		ACTION
1	INSPECT BATTERY VOLTAGE Is the battery positive terminal voltage normal?	Yes	Inspect for normal connection of the battery terminals. Go to the next step.
1		No	Charge or replace the battery, then go to Step 7. (See BATTERY RECHARGING [MZR 2.5] .) (See BATTERY REMOVAL/INSTALLATION [MZR 2.5] .)
2	INSPECT BATTERY GRAVITY Is battery specific gravity as specified?	Yes	Go to the next step.
2		No	Replace the battery, then go to Step 7. (See BATTERY REMOVAL/INSTALLATION [MZR 2.5] .)
3	INSPECT CHARGING SYSTEM Are the generator and the drive belt tensions normal?	Yes	Go to the next step.
3		No	Replace the generator and/or drive belt if necessary. (See GENERATOR REMOVAL/INSTALLATION [MZR 2.5] .) (See DRIVE BELT REMOVAL/INSTALLATION [MZR 2.5] .) Go to Step 7.
4	INSPECT FUSE CONDITION Is the fuse (SAS 10A/ABS V 20A/ABS P 40A/IG KEY1 50A/BTN 60A) normal?	Yes	Go to the next step.
4		No	Replace the fuse, then go to Step 7.
5	INSPECT DSC HU/CM POWER SUPPLY FOR OPEN CIRCUIT Disconnect the DSC HU/CM connectors. Switch the ignition to ON. Measure the voltage between following connector terminals of the DSC HU/CM (vehicle harness-side) and body ground: DSC HU/CM: Y-Body ground DSC HU/CM: AU-Body ground DSC HU/CM: AT-Body ground Is the voltage 10 V or more ?	Yes	Go to the next step.
5		No	Repair or replace the wiring harness, then go to Step 7.
6	INSPECT DSC HU/CM GROUND FOR POOR GROUND OR OPEN CIRCUIT Switch the ignition to off. Measure the resistance between the DSC HU/CM terminal B (vehicle harness-side) and body ground. Is the resistance within 0-1 ohm ?	Yes	Go to the next step.
6		No	If there is open circuit: Repair or replace the wiring harness, then go to the next step. If resistance is not within specification: Repair or replace the poor ground part, then go to the next step.
7	VERIFY THAT THE SAME DTC IS NOT PRESENT Reconnect all disconnected connectors. Clear the DTCs from the memory. (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)] .) Start the engine and drive the vehicle at 20 km/h {12 mph} or more . Are the same DTCs present?	Yes	Repeat the inspection from Step 1.
7		No	Go to the next step.
8	VERIFY THAT NO OTHER DTCS ARE PRESENT Are any other DTCs output?	Yes	Go to the applicable DTC inspection. (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)] .)
8		No	DTC troubleshooting completed.
