Relay, +54 (21)
Location: In main fuse box in instrument panel
Scheme 190
The electrical centre for most of the operations in the compartment and dashboard.
BCM control module 707 is located in the electrical centre
Electrical centre with relays, maxi and micro-fuses.
The 16 pin connector from the BCM 707 control module is connected directly to the electrical centre.
The electrical centre is fed with +30 voltage from the engine bay electrical centre 342 and is connected to the dashboard harness via a 42 pin connector.
Scheme 191
The following current circuits are distributed by the electrical centre
- Power supply +30, dashboard's electrical centre
- Power supply +15, dashboard's electrical centre
- Power supply +54, dashboard electrical centre
Scheme 192
The electrical centre can contain a greater number of fuses than those listed below. In such cases, these are not connected to a wiring harness.
