TPMS Symptom Troubleshooting - TPMS cannot be calibrated
TPMS cannot be calibrated
NOTE:
If any gauge control module or VSA system DTCs are indicated, do the troubleshooting for these DTCs first.
Check the number of miles on the gauge control module. After proceeding TPMS calibration, DATA LIST with the HDS shows the same number of miles on the gauge control module. When TPMS switch is not working, DATA LIST with the HDS shows the number of miles of the last TPMS calibration previously done.
1.
TPMS calibration check:

TPMS calibration check
?1.
Turn the vehicle to the ON mode.

?2.
Check the number of miles on the gauge control module.

?3.
Make sure the tires are inflated to the specified tire pressure listed on the doorjamb label.

?4.
Do the TPMS calibration.

?5.
Check the parameter(s) below with the HDS.
Signal
Current conditions
Values
Unit
INITIALIZED ODOMETER
    

Does the value on the HDS match the number of miles on the gauge control module?

     
YES
     
     
     
Intermittent failure, the system is OK at this time.?
     
NO
     
     
     
Go to step 2.
2.
Open wire check (TPMS SW line) 1:

Open wire check (TPMS SW line) 1
?1.
Turn the vehicle to the OFF (LOCK) mode

?2.
Disconnect the following connector.
TPMS switch 5P connector.

?3.
Turn the vehicle to the ON mode.

?4.
Measure the voltage between test points 1 and 2.
Test condition
Vehicle ON mode
 
TPMS switch 5P connector: disconnected
Test point 1
TPMS switch 5P connector No. 2
Test point 2
Body ground


Is there battery voltage?

     
YES
     
     
     
The TPMS SW wire is OK. Go to step 3.
     
NO
     
     
     
Go to step 4.
3.
Open wire check (GND line):

Open wire check (GND line)
?1.
Measure the voltage between test points 1 and 2.
Test condition
Vehicle ON mode
 
TPMS switch 5P connector: disconnected
Test point 1
TPMS switch 5P connector No. 2
Test point 2
TPMS switch 5P connector No. 3


Is there battery voltage?

     
YES
     
     
     
     
NO
     
     
     
Repair an open in the wire between the TPMS switch and body ground (G501).?
4.
Open wire check (TPMS SW line) 2:

Open wire check (TPMS SW line) 2
?1.
Turn the vehicle to the OFF (LOCK) mode.

?2.
Remove the gauge control module (Do not disconnect the connector).

?3.
Turn the vehicle to the ON mode.

?4.
Measure the voltage between test points 1 and 2.
Test condition
Vehicle ON mode
 
Gauge control module connector A (32P): connected
 
TPMS switch 5P connector: disconnected
Test point 1
Gauge control module connector A (32P) No. 23
Test point 2
Body ground

Is there battery voltage?

     
YES
     
     
     
Repair an open in the wire between the TPMS switch and the gauge control module.?
     
NO
     
     
     
Go to step 5.
5.
Shorted wire check (TPMS SW line):

Shorted wire check (TPMS SW line)
?1.
Turn the vehicle to the OFF (LOCK) mode.

?2.
Disconnect the following connector.
Gauge control module connector A (32P)

?3.
Check for continuity between test points 1 and 2.
Test condition
Vehicle OFF (LOCK) mode
 
TPMS switch 5P connector: disconnected
 
Gauge control module connector A (32P): disconnected
Test point 1
TPMS switch 5P connector No. 2
Test point 2
Body ground


Is there continuity?

     
YES
     
     
     
Repair a short to body ground in the wire between the gauge control module and the TPMS switch.?
     
NO
