DESCRIPTION OF OPERATION
Interior Lighting With/without Time Delay
For certain markets and/or models, the interior lighting circuit incorporates relay 151 which delays switching off the interior lighting for a certain time.

The interior lighting and time-delay relay are supplied with current via fuse 16, the relay is also supplied from the +15 circuit.

The interior lighting comes on when a door is opened. Door switch 54 closes and relay 151 operates because its T terminal is then grounded.

When the door is closed the door switch opens and the circuit is broken. Since the relay's time-delay circuit maintains the ground connection across contacts T and 31,the interior lighting remains on.

The time delay is about 15 seconds, but will be interrupted if the ignition switch is turned to the Drive position. Relay terminals 15 and 30 will then both be supplied with positive current, at which point the relay releases and the ground circuit across contacts T and 31 is broken.

FAULT DIAGNOSIS HINTS
1. Check that fuse 16 is intact and supplied with current.
2. Check that lamps 50C and 50F are OK and supplied with current.
3. Check that terminal 30 of relay 151 is supplied with current.
4. Turn the ignition switch to the Drive position. Check that fuse 13 is intact and supplied with current.
5. Check that relay terminal 15 is supplied with current.
6. Check that switch 53 is in working order.
7. Check the door switches, connectors, wiring harness and ground connections.
