DESCRIPTION OF OPERATION
Cars for certain markets are pre-wired for the installation of a mobile telephone, for instance. Current from fuse 20 (+30 circuit) and fuse 13 (+15 circuit) is supplied via a special 4-pin connector, which also has a ground connection.

IMPORTANT
1. When fitting a mobile telephone, etc., the lead from the +15 circuit cannot be used as a power supply lead and must only be used for operating relays.

2. When using a mobile telephone or other type of transmitter inside the car, it must always be connected to an external aerial.

FAULT DIAGNOSIS HINTS
1. Check that fuse 20 is intact and supplied with current.
2. Check that current is supplied to pin 4 of 4-pin connector 372 (H4-3).
3. Check that fuse 13 is intact and supplied with current.
4. Check that current is supplied to pin 1 of 4-pin connector 375 (H4-3).
