One-Push Start Troubleshooting Tips
Currently Applies To: ’13 and later ILX, ’13 and later RDX, and ’14 and later RLX
Got a one-push start vehicle with one of these
symptoms?
• The engine cranks, but won’t start.
• The engine starts, but then stalls.
• The engine start/stop button turns on electrical
power, but won’t crank the engine.
• The engine start/stop button won’t turn on
electrical power and the engine won’t crank
Here’s the best way to find and fix the problem:
1. Press the lock/unlock buttons on the keyless
access remote.
Does the remote’s LED blink?
Yes – Go to step 2.
No – Check the remote battery condition and
installation. If it’s OK, check the water
detection sticker on the inside of the back
panel:
White or white with red dots - No water
damage, go to step 2.
Solid Red - Water damage. Replace the
remote, and recheck
For more info, be sure to check out
Tech2Tech segment “One-Push Start
Problem? Check the Keyless Access
Remote for Water Damage.”
2. Press the lock/unlock buttons on the keyless
access remote.
Do the doors lock/unlock?
Yes – Go to step 3.
No – Check the remote registration.
NOTE: An unregistered remote will not
blink its LED.
3. With your foot off the brake pedal, push the
engine start/stop button.
Does the vehicle go into ACCESSORY mode?
Yes – The remote is correctly registered in the
keyless access system. Now, make sure
the vehicle goes into ACCESSORY mode
using the backup function. To do that, hold
the remote outside the open driver’s
window and push the engine start/stop
button. When the MID prompts you, touch
the button with the remote. The LED on
the start/stop button will blink up to
30 seconds until it detects the remote,
then solid for 10 seconds. Now, turn on
the vehicle.If it doesn’t go into
ACCESSORY mode, register the backup
control unit, if it does, go to step 4.
No – Check power to the keyless access
system.
4. Press the brake pedal, and push the engine start/
stop button.
Does the engine crank?
Yes – Go to step 5.
No – Check the brake switch circuit and the
starting system.
5. Push the engine start/stop button to go into ON
mode.
Does the immobilizer indicator blink?
Yes – Go to step 7.
No – Go to step 6.
6. Press the brake pedal, and push the engine start/
stop button.
Does the engine start and run?
Yes – Intermittent problem.
No – Check the PGM-FI system.
7. Check the immobilizer status in the HDS PGM-FI
Data List.
RUN – Keyless access system is OK, check the
PGM-FI system. Go to step 8.
BAN – This should cause the immobilizer
indicator to blink and the engine to start
(not just crank), then stall in 2 seconds. If
that happens, there are multiple problems
that will need more troubleshooting.
8. Turn on the vehicle using the backup function,
and make sure the immobilizer status reads RUN
in the PGM-FI Data List. This tells you the
backup system is correctly registered.
Does the status read RUN?
Yes – The keyless access and backup control
units are registered and aren’t the cause
of the starting problem. Continue with
normal troubleshooting.
No – Register the backup control unit.
Always Lube Oil Filter
Gasket Before Installing New
Oil Filter
There’s been a recent change to the oil filter
manufacturing process and, as a result, oil filters no
longer come pre-lubed.
So now, more than ever, it’s really important to lube
the oil filter gasket before installing a new oil filter.
Lubing the gasket keeps it from crimping and forming
a bad seal.
SRS Supplier Changes: What You Need to Know
Currently Applies To: ’12 TL
Because of supplier shortages from Japan’s earthquake and tsunami, vehicles came from the factory with different
SRS parts than what’s listed in the parts catalog.
At various times during production, we used parts supplied by both TRW and Continental. Each supplier has a
different way of sending signals between the impact sensors and the SRS unit. The SRS floor harness is also
different between these suppliers.
After a deployment, the SRS must be repaired with replacement parts from the same supplier that was originally
used in production. Before ordering replacement SRS parts, always check the part number on the original part
you’re replacing. Don’t rely on the parts catalog. If you install mismatched parts, you’ll wind up with the SRS
indicator on and SRS DTCs.
We’ve put together the following info to help you keep all of this straight. But just keep in mind they’re not a
substitute for checking those original part numbers

Help Keep the Key Code
Data Base Current
Whenever you replace a lock set, whether it’s
covered by warranty or not, be sure to call our
warranty department at 310-783-3240, and let them
know the new keycode for the vehicle you’re working
on. That way, they can keep their key code database
current.
And one more thing. If you need a keycode for a
1991 or earlier vehicle, don’t go to the Key Code
Inquiry on the iN; you won’t find it there. Just call our
warranty department; they’ll be glad to help you.

Lug Nut Size and Torque
Spec Are Different for 2014
MDX
Currently Applies To: ’14 MDX
Just so you know, the all-new 2014 MDX comes with
different size lug nuts than what we’ve been using on
the 2013 MDX. They’re now 19 mm instead of
22 mm.
That also means a different torque spec. You need to
torque these lug nuts to 80 lb-ft (108 N·m) instead of
94 lb-ft (127 N·m).

MIL On With DTC P2279 or P0507 After Throttle Body
Servicing
Currently Applies To: ’13–14 ILX, ’03–13 MDX, ’07–13 RDX, ’05–12 RL, ’14 RLX, ’04–13 TL, ’04–13 TSX, and
’10–12 ZDX
EDITOR’S NOTE: This article replaces “MIL On With DTC P2279 After Throttle Body Cleaning or Replacement,”
issued in May 2013.
Just cleaned or replaced the throttle body and now you’ve got one or more of these symptoms?
• Fluctuating idle
• MIL on with DTC P2279 (intake air system leak)
• MIL on with P0507 (idle control system RPM higher than expected)
What’s probably happened is the throttle plate is now in a different position from the one the ECM/PCM had
learned.
To fix this problem, the ECM/PCM has to relearn the current closed throttle position. Here’s how to do it:
1. Go to INSPECTION MENU in the HDS, and select ETCS TEST.
2. Select TP POSITION CHECK, and clear the throttle position learned value.
3. Turn off the ignition, then, turn it back on.
4. Reset the ECM/PCM.
5. Do the idle learn procedure.
6. Recheck for DTCs. If DTC P2279 or P0507 doesn’t reset, you’re done. If either one does, continue with normal
troubleshooting.
