within 12 ±5 msec after crash signal is received. Unlock pulse is 5 sec period. If crash unlock is not usedin a
particular variant then the crash input is to be left floating.
The crash sensor is normally high. A crash signal is defined as when voltage is below 1.5V. Crash input signal
characteristic: Normal hi & 200msec period ground after crash. Only one crash unlock can occur duringone
ignition on cycle.
Time specification
T1 : 200 msec.
T2 : 12 ± 5 msec.
T3 : 5 sec.
9. Auto light control
Lights must be turned on 500±100 msec. after the input light to the light sensor has been received.
Lights must be turned off 3±1 sec. after the input light to the light sensor has been removed. Head lamps must
be turned off 300msec before the tail lamps are switched off. When the headlight switch is in the auto position
and light intensity fulfilling the table below is detected, the tail lamp and the head lamps will be turned on.
These figures are based upon theuse of untinted solar glass.
The headlamps must remain on when the headlamp switch is rotated from the ON to the AUTO position until
such time that the light sensor input isevaluated as per the following table.
If the option select input is grounded, both the headlamps and the tail lamps shall illuminate when the voltage
drops below the tail lamp threshold. When the voltage rises above the tail lamp threshold, both the
headlampsand the tail lamps shall extinguish.
Tail lamp
Head lamp
ON
1.77 ± 008V
0.61 ± 0.06V
OFF
3.47 ± 0.10V
1.00 ± 0.06V
10. Tail lamp auto cut
When key is in the ignition key cylinder and tail lamp switch is on, followed by removing key from ignition and
then opening of the drivers doors will turn off the tail lamp relay. If driver door is opened first, followedby
removing key from ignition, then tail lamp is switched off.
If tail lamps have been cut automatically, and then the tail lamp switch is turned off and on, then tail lamp is
switched on and auto cut function is cancelled. If tail lamps have been cut automatically, and the ignitionkey
is inserted, then tail lamps are turned on.
11. Power window timer
When Ignition 2 is on, the power window relay output is turned on.
When Ignition 2 is turned off the power window feed is maintained on for 30 seconds and then turned off.
If the driver door or assist door is opened during 30 sec interval the output shall be turned off immediately.
If doors are open and ignition 2 is then turned on, the output shall be turned on immediately. If doors are
open and ignition 2 is then turnedoff, the output shall be turned off immediately.
