| A.1 | Circuit 15 power output, supplies several subsystems | 12 VDC with key in steering lock position "2" | |
| A.2,3 | Circuit 30 power input supplies EIS ECM | 12 VDC at all times | Feed from battery via X4 |
| B.3 | Main ground to W1 | Approx. 0 Ohms to ground | |
| B.9 | Circuit 50 starter signal output | Key held in starting position 12 VDC | Feed to engine ECM via K40/2 |
| B.10 | CAN Class B bus (high side). Mid speed data transfer bus input and output, exchanges data with other ECMs | No reliable test. Check continuity of wiring. Approx. 5 VAC when data is on bus | Note 1 |
| B.11 | CAN Class B bus (low side). Mid speed data transfer bus input and output | See pin B10 | |
| Note 1 | N73 is gateway for data exchange between CAN Class B and Class C bus. | ||
