itcc maint1 light is red
Thread Content
The maint1 light on the itcc is red; from the start there was an AI fault. After removing it and replugging it in, the fault disappeared. However, all three maint1 lights on the MP are red. So I removed one of the MPs after some time, but only the maint1 light on the second MP went out, while the other two remained red. Please ask an expert to help analyze and give some advice
The maint1 light, which is red, can also be in a ready state or blinking
Connect to the diagnostic software to see what specific error is reported.
The third type of fault. . Currently, MP A C are all in the maint1 red state, while pass and others are green. How can this problem be resolved? Thank you very much for providing this diagram.
From the picture you sent, it seems that PASS is green, active is yellow, and maint1 is red; this indicates that the faulty battery is out of power. How long has it been in use?
