STEP 3. Check the following harness wire.

• The wire between data link connector D-118 (terminal 7) 

and TPMS receiver connector G-28 (terminal 1)

Q: Is the harness wire damaged?

YES : Repair or replace it. And then go to Step 4.
NO :  Replace the TPMS receiver (Refer to 

P.31-96

) and 

execute "Tire Pressure Sensor ID Registration" on 
scan tool MB991958 "Special Function" (Refer to 

P.31-89

). And then go to Step 4.

STEP 4. Retest the system.

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) Retest the system.
Q: Does the scan tool communicate with the TPMS 

system?
YES : 
The procedure is complete.
NO :  Repeat this procedure from Step 1.

TERMINAL VOLTAGE CHECK CHART
Measure the voltages between terminal 6 (ground terminal) 
and each respective terminal.

.

TPMS RECEIVER GROUND CHECK
1. Turn the ignition switch to the "LOCK" (OFF) position and 

disconnect the TPMS receiver connector.

2. Check the resistance and continuity between terminal 6 of 

the harness connector and body ground. The resistance 
should measure less than 2 ohms.
