LED Description Troubleshooting Comment
Flashes red x 1
CAN/J1850 not de-
tected.
Check the Orange/Green - Orange/Brown

error.
Bypass calculation failed. Reset the module
and try again.
Might be caused by a bad reading in the first pro-
gramming attempt or by an unknown bypass value.
If a second attempt fails, connect the module to
XPRESSKIT and call Tech Support with the module
ID in hand.
