DESCRIPTION
This service bulletin illustrates the conditions when a TPMS warning light may illuminate, why it illuminated and
how to properly initialize the system.
The Tire Pressure Monitoring System (TPMS) monitors the tire pressure of all four tires indirectly using the data
sent from the ABS wheel speed sensors. If the air pressure of one or more tires is too low compared with the
specified value (the initial value learned by the system), the system warns the driver with the TPMS warning
light in the instrument cluster and a beep sound. To allow the TPMS to operate correctly, it is essential that the
TPMS be initialized to learn new conditions whenever a tire related service is performed.

PRE-DELIVERY INSPECTION (POI) STEPS 1, 3 AND 4:
To ensure a problem free vehicle sales delivery, POI Step ~'.(VEHICLE RECEIVING PROCESS), POI Step 3
(MAZDA NEW CAR GET READY INSPECTION)," a"h'd Step 4 Smart Start Guide (CUSTOMER DELIVERY
CHECKLIST) have been revised to include the TPMS initialization procedure. Failing to complete the TPMS in"itialization wm cause the T.PMS warning lighttc;> illuminate aften the customer takes delivery ofthe vehicle. This
may result in:
• Negative customer sati.sfaction due to comeback repairs.
• Negatively impact your dealerships IQS scores.
• POI claim debit. ·
When any of the services below is performed, BE SURE TO INITIALIZE THE TPMS BEFORE.DRIVING THE
VEHICLE by pushing and holding the TPMS Set Switch on the dash (until the TPMS warning light-fla§h~~s two
times and
the warning beep
sounds once).

INCORRECT INITIALIZING:
Customer complaints have been rep,ortedwhere the TPMS ;warnin~ light,is un.necessarily illuminated because
the TPMS initialization was not performed ~()ffE'!c,tly. This. service information addresses these cases and the
· ·
·
·
action to be taken,.

CASES WHERE THE TPMS WARNING LIGHT IS ILLUMINATED DUE .TO INCORRECT TPMS INITIALIZATION:
NOTE: BE SURE TO PRESS AND HOLD THE TPMS SET SWITCH AFTER TIRE PRESSURES ARE
ADJUSTED AT POI.
Refer to the on-line MS3 instructions or the Workshop Manual (section 02-12 TIRE PRESSURE MONITORING
SYSTEM INITIAU~TION PROCEDURE).

SALES DELIVERY:
Example 1: The tire pressures were adjusted at POI, but the TPMS initialization was no't performed. The TPMS
warning light was illuminated right after vehicle delivery.
Tire pressures are set at the plant around 50 psi (350kPa) a.nd the. TP;MS is \11itialized. If the TPM$ iniijal,ization
is not performed after the tire pressures are adjusted down at POI, the TPMS.determines that the tire pressures .
have dropped and the TPMS warning light illuminates.
'·,
Example 2: For the vehicle in Example 1, the dealer found the tire pressures yvere corr,ec.tr: therefore, pushed
the TPMS set switch, then delivered the vehicle. Right after the vehicle was delivered; the Misuse PreveAtion
Logic operated and the TPMS warning light illuminated again.

Misuse Prevention Logic
The CX-5, 2014 Mazda3 and 2014 Mazda6 use an indirect TPMS (does not measure the tire press1,1res
directly). In order to prevent the system from learning tire pressures that may not be within the tire manufacture
·
specifications, "Misuse Prevention Logic" has been adopted .as,a warning system.
If the TPMS is initialized without adjusting the tire pressures (even though the TPMS warning light is illuminated), the Misuse Prevention Logic will illuminate the TPMS warning light.
The data for the tire pressure at the time the TPMS warning light illuminates is compared to the data for the tire
pressure at the time the TPMS initialization was performed. If the difference in pressure is within the specification, the TPMS warning light will illuminate again. This prevents the system from learning tire pressures that
may not be within the tire manufactures spe~s.
There is one type of mis-use prevention logic for the 2014 CX-5, 2014 Mazda3 and 2014 Mazda6, Type B.
There are two types of mis-use prevention logic for the 2013 CX-5, Type A and Type B.
Type A and Type B can be identified by the first four digits of the part number (A) of DSC HU/CM (B) which is
indicated on the label adhered to the DSC HU/CM.

REPAIR PROCEDURE
If the cases mentioned above are encountered, inspect and measure according to the ·following procedures.
When the TPMS warning light illuminates, even though the tire pressures are within specification, the following
reasons (A and B) are possible:
·
·

(A) The TPMS detected the tire pressure decrease:
• The vehicle in Example 1 applies to this ca!?e.
• Tire .pressures were adjusted to the specified value, but the initialization was not performed by the dealer at
. PDI. Previously, the tire pressures were adjuste'd to a higher value than the specification. Then the tire pressures were decreased and the warning tight illuminated.

(8) The TPMS Misuse Prevention Logic activated:
•, The vehicle in E~ample 2 applies to this case.
• The customer pressed the TPMS set switch without adjusting. the .tire pressures.
·-·

'

i;

;

To distinguish between reasons A and B, conn.ect IDS,, go !o "IDS.Tool 'Box > Operational Record > TPMS >
Read Operational Record" and confirm the oet6n1eter, eJ~p~e;d.91:1ys, v~bicle speed, etc. at the time the. TPMS
set button was pushed and the warning light 'illuminated'.
· · ·
; •'..,

NOTE:

>

.'! . ' ;

...

TheTPMS initiali~tion at the plaht may not be' recorded.
Even if the TPMS set switch was pressea at POI, the TPMS initialization might not have been per·formed ifthe battery was discorll')ectec:Lafter pushing the !PMS. set switch and before the learning
prqess.

Misuse Prevention Logic Reset:
Depending on mis-use prevention logic type, the misuse prevention logic can be reset. :

Type A

Proceed to Action 1

Type B

Proceed to Action 2

• i

Misuse Prevention Logic Reset
\,'

ACTION 1 (Type A Misuse Prevention Logic Reset)
Increase the tire pressures by 7 psi ~50kPa'}' [specified value + 7 psi (50kPa)] and perform the TPMS initializa- ·
tion procedure to let the system learn the tire pressure.
·
1. Adjust all four (4) tires pressures to the specified value+ 7 psi (50kPa).
2. Press and hold the TPMS Set Switch on the dash until the TPMS warning light flashes one or two times and
the warning beep sounds once.

3. To initiate TPMS learning, drive the vehicle over 20 minutes at one of the constant speed ranges indicated in
the table below.
CAUTION:

Drive carefully and pay close attention to the changed vehicle driving characteristics with the
increased tire pressures.

NOTE: TPMS learning is temporarily suspended when braking or turning the steering wheel, so try to drive
the vehicle on a straight road with a smooth surface without stopping as much as possible.

If TPMS l!!arning has not been como!eted'. rei>eatsteps beginning with Step 3.
NOTE: For the TPMS unit data processing to change the status from "Learning" to "Learned", turn the ignition OFF, close the doors and let the vehicle sit for m.ore·than five (5) minutes..
5. After the TPMS learning has been completed:

adj~! \he.tire pressures to thecorrect specification.

6. Initialize the TPMS by pressing and holding the TPMS·setswitch on the dash until the TPMS warning light
flashes one or two times and the warning beep sounds once.
\.

ACTION 2 (Type B Misuse Prevention Logic Reset)

. >,,;

Using IDS Version 81 or Higher
1. Park the vehicle on safe, level ground.
2. Adjust all four tire pressures to the specification while the tires are cold. (See tire label located on the
driver's side B-pillar or edge of the driver's door frame)
CAUTION: Cold tires means leaving the v.ehicle for 1 ti or, i!Jhe vehicle is driven, do so. within 1 mile\1.6
km).
3. Connect the IDS to DLC-2.
4. After the vehicle is identified, select the following items from the initial screen of the IDS. ··
a. Select "Chassis"
' ·
·
b.. Select "ABS/DSC'"
c. Select "TPMS Reset"
NOTE:
This IDS reset can be performed anytime the TPMS Warning Light is illuminated.
When the tire pressure monitoring system initialization is performed, learning initiates. Learning is
completed by driving the vehicle for approx. 20 min.
While the tire pressure monitoring system is undergoing learning, its primary functions do not operate.
