the harness side.

(2) Measure the resistance between terminal 6 and ground. It 

should measure less than 2 ohms.

Q: Is the measured resistance less than 2 ohms?

YES : Go to Step 9.
NO :  Go to Step 7.

STEP 7. Check the following connector.

• TPMS receiver connector G-28

Check the connector for loose, corroded or damaged terminals,

Q: Does the TPMS warning light illuminate?

YES : Replace the TPMS receiver (Refer to 

P.31-96

) and 

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