| Circuit 30 | Power input supplies ignition/starter switch | 12 VDC at all times | Feed from battery via X4 |
| Circuit 50 | Power output supplies Engine ECM. Starter lock-out signal is activated by K40/4 |
12 VDC with key in steering lock position "3" | Note |
| Circuit 15 | Power output, supplies several subsystems | 12 VDC with key in steering lock position "2" | |
| G2 | |||
| B+ | Circuit B+ power output, supplies circuit 30 and charges battery when engine is running | Ignition on 12 VDC when engine is running |
|
| D+ | Circuit D+ signal output to charge indicator lamp A1e5 | Ignition on 12 VDC when engine is running, A1e5 not lit 0 VDC when engine is not running, A1e5 lit |
|
| A1 | |||
| 1A.9 | Circuit 15 power input, supplies charge indicator lamp A1e5 | 12 VDC with ignition on | Also supplies other electric circuits in instrument cluster |
| 1B.1 | Circuit D+ power input to charge indicator lamp A1e5 extinguishes when applied | Ignition on 12 VDC when engine is running, A1e5 not lit 0 VDC when engine is not running, A1e5 lit |
D+ is also processed into 61e as engine running recognition signal |
| Note | Signal from gear shifter in position P or N is transfered via CAN to Engine ECM | ||
