System Inspection

■ Check Charging System 

1. Start the engine and raise the engine speed to 2, 500~3, 000 RPM.
2. Turn ON all electrical loads by turning on the headlamps, and by turning on the high blower motor, etc.
3. Monitor the battery (ignition) voltage parameter on the GDS data list.

   Specification: 

   Ambient temperature °C (°F)	Reference Voltage (V)
   -20 (-4)	Approx. 14.2~15.4
   20 (68)	Approx. 14.0~15.0
   60 (140)	Approx. 13.7~14.9
   80 (176)	Approx. 13.5~14.7

4. Is the battery voltage within the specification?

   YES 

   • Check for poor connection between PCM and component: backed out terminal, improper mating, broken locks or poor terminal to wire connection. Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.

   NO 

   • Possibility of charging system malfunction. Repair or replace alternator and battery. Refer to "CHARGING SYSTEM - 2.0L - SONATA (EXCEPT HEV) ". And then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
