Supplemental Diagnosis Table

The engine does
not start using
the RES feature
(see steps
a-d above)

Possible Cause

Confirmation of Cause

Resolution

1

ECM has not
completed the shutdown
procedure after
engine/ignition OFF.

ECM has to end the
shutdown process and save
data prior to allowing RES to
operate. The shutdown
process takes 6 seconds to
complete after engine/ignition
is turned OFF.

Wait 6 seconds after the
engine has stopped before
attempting RES activation.

2

RES is correctly activated
more than 2 times
consecutively
OR
RES is activated once, and
with the engine running,
another request is generated.

Not possible to confirm how
many times RES has been
activated.

Perform steps a-d above.
This action will reset counter.

One or more Intelligent Keys
for the vehicle are still inside
the vehicle.

With all known Intelligent
Keys outside and out of
range of the vehicle, try to
turn ON the ignition with
push-button ignition switch.
If the ignition turns ON, at
least one Intelligent Key is
inside the vehicle.

Find and remove all
remaining Intelligent Keys
from the vehicle, lock doors
with the Intelligent Key, and
then perform RES.

Possible Cause

Confirmation of Cause

Resolution

Environmental factors block,
reduce, or scramble signal
strength from Intelligent Key
to BCM.

Devices inside the vehicle
may cause RF interference,
such as after-market alarms,
highway toll passes, cell
phones or garage door
opener remotes.

Remove all devices that may
cause RF interference inside
the vehicle.

Stop lamp switch is
misadjusted or inoperative,
giving a stop lamp switch ON
signal (or brake pedal is
applied).

Stop lamp switch adjustment
may not
be within specification.

Confirm switch operation
using ABS Data Monitor:
Stop Lamp SW = OFF (with
brake pedal released, not
pressed)
Adjust / replace stop lamp
switch.
Check as needed:

The engine does
not start using
the RES feature
(see steps

Hood may not be
completely closed.

Hood is open.

Security system is currently
activated (activation keeps

Note: The horn may not be
heard and lights may not be
flashing.

Check the Security system
activation by trying to start
engine normally (with pushbutton ignition switch).
Note: The engine will not
start with Security system
activated.

 Verify the hood is
closed.
 Confirm the hood
switch connection
is secure.
 Confirm hood switch
operation using IPDM
Data Monitor:
Hood Switch-2 = ON
(when hood is closed)
 Adjust / replace
switch.

Turn OFF/deactivate the
Security system (unlock
doors with Intelligent Key). If
condition persists, diagnose
further using ESM.

15

RES is attempted from within
the vehicle.

RES can only operate
from outside the vehicle
with doors locked.

Exit the vehicle WITH the
Intelligent Key, lock the
doors, and within 5 seconds
activate RES.

Specific DTCs may prevent
RES from operating: B261B,
B26FE, B26FD

Confirm with C-III plus
that no DTCs are stored.

Clear DTC(s) with C-III plus.
If DTC(s) persist, perform
further diagnosis using the
ESM.
