PRE-RELEASE
Control module power supply
| Control module power supply |
| Battery voltage +30 |
Voltage +30 is supplied via fuse 8 (22a) to pin 13 of the SID connector.
| Battery voltage +15 |
Current +15 is supplied via fuse 27 (22a) to pin 30 of the SID connector.
The SID control module is activated with the +15 voltage.
| Diagnosis |
If +30 is not present, the main instrument unit information display will be switched off and diagnostic communication will not be possible.
If +15 is not present, the information display will be switched off but can be activated via the bus. Diagnostic communication, with limited functions, is available if the ignition is switched to ON.
The SID control module will not generate a diagnostic trouble code if no voltage is present from either the +30 or +15 circuits.
