Charged Too High

ECM-8010 BATTERY VOLTAGE
CHARGE TOO HIGH

Checking charge voltage



Hint: When a battery charger or starter unit is connected to the battery it is important that the correct voltage is set. Charging at too high a voltage can cause diagnostic trouble codes (DTCs) to be stored.

- Start the engine.
- Connect a voltmeter between battery terminals.

Battery voltage should be less than 16 V.

Is the battery voltage OK?
Yes - Continue below.
No - Skip to "Checking Charging System"


Intermittent fault
The control module has earlier registered too high voltage. This may have been caused by a battery charger with faulty voltage being connected to the battery or an intermittent fault in the charging regulator.


Fault-tracing information
If the fault is intermittent, do not verify fault-tracing if the fault does not recur.

Checking Charging System
Check charging system for too high charge voltage.


Fault-tracing information
If the fault is intermittent, do not verify fault-tracing if the fault does not recur.
