1.1.3.2.1.3.1. Test voltage supply of circuit 87. ( Check using actual value )
Test prerequisite
- The voltage test at component G1 (Battery) is o.k.
- Ignition ON
Status of relevant actual value:
- Battery voltage:Warning! Communication with ECU required.
Specified value
- Battery voltage[11.0 ... 15.0] V
Question:Is the actual value o.k.?
YES
The actual value is okay.End of test
NO
The actual value is not o.k.Possible cause and remedy
- Test voltage supply of circuit 30.
- Test voltage supply of circuit 87.
