repair and/or diagnostic support. Please also assist customers with the required preconditions when

1. Remote Engine Starter Preconditions and Tips:
Utilize the following table as a guide to successful operation of the control apps (cell phone) based
remote engine starter system.
NOTE: Network/cellular coverage may influence response time from each command. Sending
multiple commands in a short period of time is not recommended. The remote start by key FOB is only

2. Remote Door Lock/Unlock Preconditions and Tips:
Utilize the following table as a guide to successful operation of the control apps (cell phone) based door
lock and unlock system.
NOTE: Network/cellular coverage may influence response time from each command. Sending multiple
commands in a short period of time is not recommended. Make sure door locks work normally by panel
switch and FOB, and that the remote door lock operation is not customized to OFF.
3. Vehicle ECU Initializations:
Ensure the vehicle settings and initializations for door lock and remote engine starter are correct as
per the repair manual.
A. Make sure that “Communication Remote Engine Starter” in Techstream customized settings that
is designed/intended for an add-on or aftermarket RES kit is set to “Not Available”.
Customize>Others>Communication Remote Engine Starter > Not Available
EXAMPLE:
B. With the related DTCs cleared, perform the following registrations/initializations:
i. Smart Key Live>ECU Communication ID Registration>Remote Engine Starter
ii. Smart Key Live>ECU Communication ID Registration> I.D. Code Box/Steering Lock
iii. Telematics>Remote Door Lock Setting
NOTES:
 If settings are improper, related DTCs may include: B126A, B2779, U0198, and U1117.
 Performing these specific “initializations” can be safely done even if not needed.
 Make sure the Telematics initialization utility includes the words “door lock” as a general
“initialization” titled utility may be unrelated and not supporting the door lock/unlock app.
 Make sure that any customized setting for remote door locks has the feature enabled.
 Do NOT use the Telematics “activation” utility for existing DCMs with established accounts. [This
is only for new off-the-shelf DCMs when first installed into vehicles.]
