PURPOSE
Some vehicles with One-Touch Start System (OSS) may exhibit a condition where the ignition cannot
be turned off when battery voltage drops. When battery voltage drops, the vehicle cannot perform
CAN communication correctly and will go into the fail-safe mode. Fail-safe mode prevents the
vehicle from turning the ignition off even when the ignition switch is pushed.
This TSB instructs dealers to explain to customers that the battery voltage should be checked during
routine maintenance, and that proper battery voltage should prevent the condition from occurring.
BACKGROUND
In order to prevent the engine from stopping if the ignition switch is pushed accidentally while driving,
the driving condition is being monitored via CAN (Controller Area Network) communication. If CAN
communication fails, due to low battery voltage, the driving condition cannot be monitored and the
vehicle enters fail-safe mode. Fail-safe mode judges the vehicle as being in a running state (even if
the engine is not running), and prevents the ignition from being turned off.
AFFECTED VEHICLES
The following vehicles with One-Touch Start System (OSS):
D
2014-2017 Mirage
D
2017 Mirage G4
D
2014-2017 Outlander
D
2011-2017 Outlander Sport/RVR
EXPLANATION TO CUSTOMER
Dealers should explain to the customer that since a drop in battery voltage causes the issue, the
battery condition and voltage should be checked as part of routine vehicle maintenance. When battery
voltage is normal, the issue should not occur.
Also explain the following points to the customer:
D
When the ignition cannot be turned off, doors also cannot be locked by the Keyless Operation
system. The emergency key may be used to lock the doors.
D
The steering lock cannot be operated.
D
Refer to the Owner's Manual, “For emergencies” section, to properly jump-start and/or charge
the battery.

REPAIR PROCEDURE
1. If the vehicle ignition cannot be turned off due to low battery voltage, jump-start and/or charge the
battery following all instructions and warnings in the Owner's Manual, “For emergencies” section.
2. Using MUT-III, perform an “Erase and Read all DTCs” to clear any DTCs that may have been set due
to this condition. Confirm that DTCs do not reset.
3. If any DTCs do not clear, diagnose and repair following instructions in the Service Manual.
4. If the battery cannot be charged to proper voltage, or if the battery is dead, advise the customer to
replace the battery with a new one.
