Diagnostic procedure

WARNING: This page is about a different car, the 2016 Mazda CX-5. However, it is still accessible from the selected car via links, so may be relevant.

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 [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) (See BATTERY REMOVAL/INSTALLATION [SKYACTIV-G 2.0, SKYACTIV-G 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 [SKYACTIV-G 2.0, SKYACTIV-G 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 [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) (See DRIVE BELT REMOVAL/INSTALLATION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) Go to Step 7.
4	INSPECT FUSE CONDITION Inspect the following fuses. SRS1 7.5A ABS/DSC S 30A ABS/DSC M 50A Is the fuse normal?	Yes	Go to the next step.
4		No	Replace the fuse, then go to Step 7.
5	INSPECT DSC HU/CONTROL MODULE POWER SUPPLY FOR OPEN CIRCUIT Disconnect the DSC HU/Control Module connectors. Switch the ignition ON (engine off). Measure the voltage between following connector terminals of the DSC HU/Control Module (vehicle harness-side) and body ground: DSC HU/Control Module: A-Body ground DSC HU/Control Module: B-Body ground DSC HU/Control Module: Q-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/CONTROL MODULE GROUND FOR POOR GROUND OR OPEN CIRCUIT Switch the ignition to off. Measure the resistance between the DSC HU/Control Module terminal AL (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.
