Check CAN Bus Lines for Short Circuit

Transcription

1 30 N COMMUNITION N COMMUNITION SYSTEM Check N us Lines for Short Circuit DESCRIPTION The N bus lines are considered to be shorted when the resistance between terminals 6 () and 4 () of the DLC3 is below 54 Ω. Symptom Resistance between terminals 6 () and 4 () of the DLC3 is below 54 Ω.
