Fault symptoms
If a fuse is missing, then SID and MIU are "black" and Trionic is shown as being a fused unit. Communication for diagnostics is still possible, however, even though a fuse is missing.
Diagnostic help
+15 can be read with scan tool.
Interior lighting does not come on when the key is removed from the ignition and no doors are opened.
+B can be read with the scan tool.
Varies depending on fault characteristics.
