Message: [QUOTE="G Racing, post: 116386, member: 31"] will this help you? Vehicle Security Module The vehicle security module receives inputs from the following: ^ door ajar switches ^ keyless entry keypad ^ ignition switch ^ remote keyless entry transmitter The vehicle security module uses these inputs to control an output signal to the instrument cluster which controls the internal battery saver relay and interior lamp relay. Interior Lighting Systems The instrument cluster grounds the battery saver relay and interior lamp relay coils when any door ajar switch is opened, or the interior lamp (headlamp) switch is closed. The interior lamp relay then supplies voltage to the interior lamp circuit. Vehicle speed must be less than 24 kph (15 mph) for the instrument cluster module to ground the interior lamp relay. The interior lamps will remain illuminated for up to 25 seconds after all doors are closed unless the instrument cluster module receives an input from any of the following: ^ voltage from the ignition switch ^ a vehicle speed signal ^ input from the keyless entry keypad through the vehicle security module ^ input from the remote keyless entry transmitter unlock or panic switch through the vehicle security module Illuminated Entry Illuminated entry is activated when a keyless entry keypad switch provides an input to the vehicle security module or when the vehicle security module receives an unlock signal from the remote keyless entry transmitter. The vehicle security module then requests that the instrument cluster module activate the battery saver and interior lamp relays by providing ground to the relay coils. Illuminated entry is deactivated when the vehicle security module receives a lock signal from the remote keyless entry transmitter or receives an input from the keyless entry keypad. Illuminated entry will also be deactivated when the instrument cluster module receives input voltage from the ignition switch. Battery Saver The battery saver is activated when the instrument cluster module is not receiving voltage input from the ignition switch (OFF position). The instrument cluster module will then provide ground to the battery saver relay coil, activating the relay, for a period of 10 minutes with the interior lamp (headlamp) switch in the off position, or a maximum period of 30 minutes with the interior lamp (headlamp) switch in the on position or a door is ajar, provided that the instrument cluster module does not receive any other input signals within the time-out period. The activated battery saver relay switches voltage to the demand lamp circuit and the interior lamp relay coil. After time-out, the instrument cluster module disconnects ground from the battery saver relay coil, disabling the demand lamp circuit. [/QUOTE]
