Signal Too High

Signal too high

Checking charge voltage

Hint: It is important that the correct voltage is set when the battery charger or start unit is connected to the battery.
Charging with too high a voltage can cause a diagnostic trouble code (DTC) to be stored.




- Engine running
- Connect a voltmeter between the battery terminals.
The battery voltage must be less than 16 V.





Is the battery voltage OK?

Yes - Intermittent fault

No - Checking the charging system

-------------------------------------------------

Checking the charging system
Check the charging system for excessive charge voltage. See relevant information.

Intermittent fault
The combustion preheater module (CPM) has previously registered too high a voltage. This may have been caused by the connection of a battery charger with incorrect voltage to the battery, or by an intermittent fault in the charging regulator.
