2.2.67. SPN 168, FMI 0, Battery voltage: Voltage ABOVE NORMAL (>17V(12V)) (>32V(24V)).ΒΆ

Description

The EEM4 monitoring system has detected a too high battery voltage.

  • The fault code limit for the 12V systems: 17 V.
  • The fault code limit for the 24V systems: 32 V.

Reaction in EEM

The FC is stored and the warning lamp is activated. The CAN message indicates an active fault.

Solution

First save the error log and then do the procedure that follows:

  • Verify and measure that the supply voltage is correct.
  • Make sure the generator is working correctly and measure that the charging voltage is correct. (see Engine ECU power supply)
