What does it mean when my car says check charging system?
What’s happening when the battery/check charging system light comes on? Whenever this light goes on, it means that the vehicle is running solely on battery power. If the problem continues and your charging system fails, the battery won’t be able to recharge and it will soon run down, leaving you with a dead battery.
Why does my Toyota Tomorrows Charger not charge?
If the decoupler pulley fails, the alternator won’t charge because it is “free-wheeling.” Next, inspect the battery warning light to see if it illuminates as the ignition is turned on and if it turns off as the engine is started. If the battery warning light turns off with the engine running, accelerate the engine speed to 2,000 rpm.
How does a Toyota battery charging system work?
Most Toyota charging systems integrate their voltage regulators into the alternator assembly. While charging voltage specifications vary according to application, the voltage regulator generally adjusts battery-charging voltage according to ambient air temperature.
What kind of voltage does a Toyota Charger need?
Photo 1: This 10.64 battery cranking voltage is well above Toyota’s threshold of 9.6 volts, which means the battery isn’t causing the charging system problem. According to Toyota, a dynamic battery state of charge (SOC) and state of health (SOH) test can be performed with the aid of a simple voltmeter.
What does diagnostic code mean on Toyota Charger?
Depending on the diagnostic capability of the scan tool and the software written into the engine control module (ECM), the scan tool might display diagnostic trouble codes (DTCs) indicating problems within the charging system.
