SV 19 - (-) AUX 2 Trigger INPUT: This setting allows any PIC programmed with value 19 to be used
to activate AUX2 output (timing output based on feature 4-02) with a Pulsed or latched
ground/negative source.
SV 20 – (-) Closed Loop Input: This setting allows any PIC programmed with value 20 to be used as a
closed loop alarm trigger. While armed; when this input is grounded the system will consider it
a closed loop circuit, once ground is removed it will trigger an alarm event. A good use case
example would be protecting catalytic converter.
SV 21 – (-) Closed Loop Input: This setting allows any PIC programmed with value 21 to be used as a
closed loop alarm trigger. While armed; when this input is grounded the system will consider it
a closed loop circuit, once ground is removed it will trigger an alarm event. A good use case
example would be protecting catalytic converter.
SV 22 – (-) NEG. Valet Input: This setting allows any PIC programmed with value 22 to be used as an
enter/exit Valet mode input. To enter/exit Valet mode using this input, it must see ground for a
minimum of 5 seconds, then ground pulse input 5 times. This PIC wire can be used with a
momentary or latching toggle switch to enter/exit valet mode. When using valet mode for
security purposes, make sure the switch is mounted discreetly but is still accessible by the user.
**There are several benefits to using the PIC inputs:
Example 1: 4 N/C door inputs would be available for Manual transmission scenario without requiring
a module, wire cutting, resistors, diodes, or relays
Example 2: 4 individual (-) door inputs could be connected (with no diodes) eliminating the need for
diodes to isolate the door pins from each other when connecting multiple door pins to 1 door
input on the CM
Example 3: Allow for a N/C hood pin or Trunk pin input that does not require a module, wire cutting,
diodes, resistors, or relays
Example 4: will make the CM an install more efficient by allowing for unused inputs to be
reprogrammed for other functional inputs
Special Option Group 4
This special option group allows you to program the output function of the High Current Programmable
output (HCP). The settings values changes will apply to both High Current (HC) and Low Current (LC)
Outputs found on CN1 and CN2. NOTE: Using the HC and LC outputs simultaneously may result in
damage to the CMX. OP500 MUST be updated with v.33 to access the HCP features on the CMX
HCP 1 - Green/White (default) – Low Current (LC) Programmable Output (2A MAX) (HC 10A
MAX): This positive (+) parking light (default setting) wire activates with lock, unlock,
remote start, or during troubleshooting diagnostics.
HCP 2 - White – Low Current (LC) Programmable Output (3A MAX) High Current (HC 20A
MAX): Accessory 12V positive (+) output (default setting). This wire can be connected to
the vehicle accessory / HVAC blower motor wire. The proper wire will test 0V with the key
in the off position, (+) 12V while key is in the on position, 0V while cranking and back to (+)
12V-14V when the key is returned to the on position
HCP 3 - Blue – Low Current (LC) Programmable Output (3A MAX) High Current (HC 20A
MAX): Positive 12V (+) Ignition output (only) (default setting) This wire can be connected
to the vehicle 2
nd
Ignition wire. The proper wire will test 0V with the key in the off position,
(+) 12V while key is in the on position, (+)9V-12V while cranking and back to (+) 12V-14V
when the key is returned to the on position.
