Supply voltage too low.
â–¶ How to fix
Check the alternator, batteries, connectors and wiring.
What you'll see
No driver-visible symptom recorded.
System reaction
When the voltage is low, there can be problems to activate the solenoid valves depending on how low the voltage is. The fault code is only generated when the engine speed is above 400 rpm. Therefore not during the cranking procedure.
Diagnostic depth
Detection
The supply voltage has been too low, below 16 V. This DTC only occurs when the engine speed is greater than 400 rpm, i.e., not while cranking.
Possible cause
Components or wiring may be defective or have a loose connection.
