STEP 12. Check the feeder cable core wire for continuity.

(1) Disconnect the following connectors.

• TPMS antenna (rear-LH) connector G-28-8

• TPMS receiver connector G-28-3

(2) Check the feeder cable core wire for continuity as below.

• The cable between TPMS antenna (rear-LH) connector

G-28-8 (terminal 1) and TPMS receiver connector
G-28-3 (terminal 1)

Q: Is there continuity between the feeder cable core wire?

YES : Replace the TPMS antenna (rear-LH) (Refer to

P.31-94

). And then go to Step 16.

NO : Replace the feeder cable. And then go to Step 17.

STEP 13. Check the following connectors.

• TPMS antenna (rear-RH) connector G-28-2

• TPMS receiver connector G-28-1

Check the connectors for loose, corroded or damaged termi-
nals, or terminals pushed back in the connector.
Q: Are the connectors and terminals in good condition?

YES : Go to Step 14.
NO : Repair it. And then go to Step 17.

STEP 14. Check the following feeder cable.

• The cable between TPMS antenna (rear-RH) connector

G-28-2 (terminal 1) and TPMS receiver connector G-28-1
(terminal 1)

Q: Is there any faults or kinks along the feeder cable

routing?
YES : Repair or replace it. And then go to Step 17.
NO : Go to Step 15.

STEP 16. Execute "Tire Pressure Sensor ID Registration"
on scan tool MB991958 "Special Function."
Q: Is the "Tire Pressure Sensor ID Registration" complete?

YES : Go to Step 18.
NO : Replace the TPMS receiver (Refer to

P.31-96

). And

then go to Step 17.

STEP 17. Execute "Tire Pressure Sensor ID Registration"
on scan tool MB991958 "Special Function."
Q: Is the "Tire Pressure Sensor ID Registration" complete?

YES : Go to Step 18.
NO : Repeat the troubleshooting from Step 1.

STEP 18. Recheck for diagnostic trouble code.
Q: Does diagnostic trouble code 22, 26, 31, 35 or 39 reset?

YES : Repeat the troubleshooting from Step 1.
NO : The procedure is complete.

DTC 23/27/32/36/41: TPMS Transmitter Abnormality (Tire Air Pressure Low)

.

TPMS DTC SET CONDITION
DTC 23, 27, 32, 36 or 41 is set when the TPMS
receiver recognized a low tire pressure from one or
more of the TPMS transmitters. At the same time this
DTC is set, the TPMS warning light illuminates.
TIRE PRESSURE THRESHOLD VALUES

.

TROUBLESHOOTING HINTS (THE MOST LIKELY
CAUSES FOR THIS DTC TO SET ARE:)

• Low tire inflation pressure

• Punctured tire

• Damaged tire valve grommet and/or valve core

• Defective TPMS transmitter

• Malfunction of the TPMS receiver

.

DIAGNOSIS
NOTE: Prior to performing troubleshooting for DTC 23, 27, 32,
36 or 41, first carry out "TPMS Inspection Procedure No.1: The
TPMS Warning Light Stays On" (Refer to

P.31-49

). If the trou-

bleshooting is not complete and DTC 23, 27, 32, 36 or 41 is
set, carry out troubleshooting as described below.

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
