TROUBLESHOOTING
INFORMATION
Complaint: Remote Control Inoperative
Common causes for this complaint:
Mis-spliced Key Unlock wire, weak or dead battery in remote, remote programmed improperly (see KNOWN
ISSUES page), remote not programmed, connectors not plugged in securely.
RS3200PLUS SECURITY SYSTEM
What to Ask and Verify What to Check
Does the panic mode
operation work?
Yes Check and correct the key unlock warning wire’s splice location (does
not apply to all vehicles).
Verify the splice connector was applied properly.
Clear the remote control codes from the ECU, then reprogram both (or
all) remotes (they may have accidentally been programmed for second
channel output).
No
Open
the
remote
control(s) and carefully clean the battery and contacts, then check the
battery for a minimum 2.7V during remote operation. Replace the battery
if necessary.
Clear the remote control codes from the ECU, then reprogram both (or
all) remotes (they may have accidentally been programmed for second
channel output).
Check the automatic door locking/unlocking function.
Complaint: System Inoperative (No Remote Arming/Disarming)
Common causes for this complaint:
Mis-spliced Key Unlock Warning wire, mis-spliced door courtesy wire, connectors not plugged in securely, Fuse
or shortpin not installed in vehicle, blown fuse in RS3200PLUS harness (does not apply to all vehicles).
RS3200PLUS SECURITY SYSTEM
What to Ask and Verify What to Check
Do the vehicle’s door
locks work with the door
switches or key?
Yes
Check and correct the key unlock warning wire’s splice location (does not
apply to all vehicles).
Verify the splice connector was applied properly.
No Confirm the door lock control connectors are plugged in securely. Discon-
nect the RS3200PLUS harness’ Door Lock Control connectors and recon-
nect the vehicle’s connectors, then try again, If there is no function, there
is probably a problem with one vehicle’s components.
Do the vehicle’s door
locks work with the door
switches or key?
Yes
Check and correct the key unlock warning wire’s splice location (does not
apply to all vehicles).

No Confirm the door lock control connectors are plugged in securely. Discon-
nect the RS3200PLUS harness’ Door Lock Control connectors and recon-
nect the vehicle’s connectors, then try again, If there is no function, there
is probably a problem with one vehicle’s components.

What to Ask and Verify What to Check
Does the head lamp
switch in the vehicle
work?
Yes Check and correct the head light wire’s splice location (applies to most
vehicles).
Verify the splice connector was applied properly.
Check for continuity between the RS3200PLUS ECU connector and the
head lamp circuit connection.
No Check the vehicle’s head lamp fuse and replace if necessary.
Confirm that the combination switch connector for the head lamp circuit is
plugged in securely.
Is there continuity
between pin 10 of the
RS3200PLUS harness’
ECU connector?
Yes Activate the panic mode and check pin 10 for pulsed continuity to ground.
If there is continuity, check fix the wire harness.
Check the RS3200PLUS ECU for signs of liquid damage; it may be nec-
essary to open the ECU case. LIQUID DAMAGE ITEMS ARE NOT COV-
ERED UNDER WARRANTY.
No If no continuity, there is a wire harness problem. Fix as necessary.

No Check the vehicle’s horn fuse and replace if necessary.
Confirm that the combination switch connector for the horn circuit is
plugged in securely.
Is there continuity
on pin 10 of the
RS3200PLUS harness’
ECU connector?
Yes Activate the panic mode and check pin 10 for pulsed continuity to ground.
If there is continuity, check fix the wire harness or check BODY ECU
signal.
Check the RS3200PLUS ECU for signs of liquid damage; it may be nec-
essary to open the ECU case. LIQUID DAMAGE ITEMS ARE NOT
COVERED UNDER WARRANTY.
No
If no continuity, there is a wire harness problem. Fix as necessary.
