OBD2 Off Time
0-600 Time in seconds after vehicle and engine
speed are zero before dropping OBD
communications with the ECU.
0 – Ignition off when vehicle and engine speed are zero.
1 – Ignition off after OBD2 off time expires
The recommended setting for hybrids and stop/start vehicles is 180,1. A longer
time can be used safely if the ECU stops communicating after the key is
removed. There is a power consumption trade off for ECUs that continue trans-
mitting after the key is removed. The default setting and recommended setting
for all other vehicles is 60,0.
