Conditions Which Generate This Code:
This code indicates that the battery circuit for the Electronic Control Module (ECM) has low voltage
while the engine is running. If battery voltage disappears without returning, the ECM will not log
this diagnostic code and the engine will shut down.
The ECM detects the following conditions:
• The keyswitch is in the ON position.
• The engine is not cranking.
• The engine is running for more than three seconds.
• For 24 Volt DC systems, the battery voltage to the
ECM is below 18 Volts for more than 0.5 seconds.
• For 12 Volt DC systems, the battery voltage to the ECM is below 9 Volts for more than 0.5 seconds.
System Response:
If equipped, the diagnostic lamp will flash and the derate lamp will come on. The ECM will normally log the diagnostic code. If battery voltage disappears without returning, the ECM will not log this diagnostic code and the engine will shut down.
Possible Performance Effect:
The engine will derate 100 percent.
The engine may experience changes in the engine rpm, and intermittent engine shutdowns or complete engine shutdowns while the conditions that cause this diagnostic code are present.
Troubleshooting:
This diagnostic code will detect low voltage in the battery circuit for the Electronic Control Module
(ECM) while the engine is running.
Perform the following diagnostic procedure: “Ignition Keyswitch Circuit and Battery Supply Circuit
– Test” Results:
• OK – STOP.
