CAUTION
• During diagnosis, a DTC code associated with another system may be set when the ignition
switch is turned to the "ON" position with connector(s) disconnected. When diagnosis is finished,
check all systems for DTC code(s). If DTC code(s) are set, erase them all.
• Tire pressure sensor ID registration must be done before any diagnosis.

TPMS DIAGNOSTIC TROUBLE CODE PROCEDURES
DTC 11: TPMS Abnormality (ID Code Not Registered)
.
TPMS DTC SET CONDITION
DTC 11 will be set if the tire pressure sensor IDs are
not registered correctly in the TPMS receiver. At the
same time this DTC is set, the TPMS warning light
flashes.
.
TROUBLESHOOTING HINT
Execute "Tire Pressure Sensor ID Registration" on
scan tool MB991958 "Special Function."
.
DIAGNOSIS
Required Special Tools:
• MB991958: Scan Tool (MUT-III Sub Assembly)
• MB991824: Vehicle Communication Interface (V.C.I.)
• MB991827: MUT-III USB Cable
• MB991911: MUT-III Main Harness B
.
STEP 1. Execute "Tire Pressure Sensor ID Registration" on
scan tool MB991958 "Special Function."
CAUTION
To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Connect scan tool MB991958 to the data link connector.
(2) Turn the ignition switch to the "ON" position.
(3) Execute "Tire Pressure Sensor ID Registration" (Refer to
Q: Is the "Tire Pressure Sensor ID Registration" complete?
YES : Go to Step 2.
NO : Go to Step 4.

STEP 2. Check the diagnostic trouble code.
NOTE: If the "Tire Pressure Sensor ID Registration" has been
completed successfully, the DTC will be erased automatically.
Q: Does diagnostic trouble code 11 reset?
YES : Go to Step 3.
NO : The procedure is complete.
STEP 3. Execute "Tire Pressure Sensor ID Check" on scan
tool MB991958 "Special Function."
All the tire pressure sensor IDs, which have been registered in
Step 1, should be displayed on scan tool MB991958.
Q: Are all the registered tire pressure sensor IDs
displayed?
YES : Replace the TPMS receiver (Refer to
). And
then go to Step 1.
NO : Repeat the troubleshooting from Step 1.
STEP 4. Execute "Tire Pressure Sensor Check" on scan
tool MB991958 "Special Function."
Q: Are all tire pressure sensor IDs displayed?
YES : Repeat the troubleshooting from Step 1.
NO : Carry out troubleshooting for DTC 22/26/31/35/39
(tire pressure sensor ID reception failure) from the
Step 3 (Refer to
DTC 13: TPMS Abnormality (EEPROM Failure)
.
TPMS DTC SET CONDITION
DTC 13 will be set if there is any fault in the TPMS
receiver's EEPROM. At the same time this DTC is
set, the TPMS warning light flashes.
.
TROUBLESHOOTING HINT
Replace the TPMS receiver.

ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(2) Connect scan tool MB991958 to the data link connector.
(3) Turn the ignition switch to the "ON" position.
(4) Execute "Tire Pressure Sensor ID Registration" on scan
tool MB991958 "Special Function" (Refer to
).
(5) Check the illumination condition of the TPMS warning light.
Q: Is the TPMS warning light still flashing?
YES : Go to Step 2.
NO : Go to Step 2.
STEP 2. Recheck for diagnostic trouble code.
Q: Does diagnostic trouble code 13 reset?
YES : Repeat the troubleshooting from Step 1.
