Is there continuity?  

YES - Repair short to body ground in the wire between the TPMS control unit and the appropriate 
initiator. 

NO - Go to step 25. 

25. Measure the voltage between body ground and the appropriate TPMS control unit connector B (20P) 

terminal (see VOLTAGE TERMINAL CHART).

Is there battery voltage?  

YES - Repair short to power in the wire between the TPMS control unit and the appropriate initiator. 

NO - Replace the appropriate initiator (see INITIATOR REPLACEMENT ). 

DTC 41: ABNORMAL SIGNAL RECEPTION ERROR 

1. Check all four wheels to make sure they are the TPMS type with the tire pressure sensor. 

Is each wheel a TPMS type with a tire pressure sensor mounted on the vehicle?  

YES - Go to step 4.

NO - Go to step 2. 

2. Install known-good TPMS wheel(s).  

3. To memorize the sensor ID(s), drive the vehicle above 15 mph (24 km/h) for 40 continuous seconds, 

or memorize the ID(s) with the HDS (see MEMORIZE THE ID WITH THE HDS ).  

4. Test-drive the vehicle.  

5. Check the VSP in the TPMS DATA LIST with the HDS. 

Is the vehicle speed indicated?  

YES - Go to step 9. 

NO - Go to step 6. 

6. Turn the ignition switch OFF.  

7. Turn the ignition switch ON (II).  

8. Check for DTCs with the HDS. 

Is DTC 85 indicated?  

YES - Go to the DTC 85 TROUBLESHOOTING . 

NO - Check for loose terminals and poor connections at the TPMS control unit. If necessary, 
substitute a known-good TPMS control unit (see TPMS INDICATOR OR TIRE(S) INDICATOR
(S) DOES NOT GO OFF, AND NO DTCS ARE STORED ), and recheck. 

9. Turn the ignition switch OFF.  

10. Turn the ignition switch ON (II).  

11. Check TPMS DATA LIST for LF, RF, LR, RR sensor status changing to "NORMAL". 

Is NORMAL indicated within one full turn of the tire?  

YES - The system is OK at this time. Clear the DTC with the HDS. 

NO - Check for loose terminals and poor connections at the TPMS control unit. If necessary, 
substitute a known-good TPMS control unit (see TPMS INDICATOR OR TIRE(S) INDICATOR
(S) DOES NOT GO OFF, AND NO DTCS ARE STORED ), and recheck. 

DTC 45: INITIATOR CIRCUIT SHORT DETECTION 

1. Turn the ignition switch ON (II).  

2. Clear the DTC with the HDS.  

NOTE:

If the HDS screen shows UNDEFINED for sensor status, turn the 
ignition switch OFF, rotate the tire 1/4 turn, then turn the ignition switch 
ON (II), and try again. If UNDEFINED is still shown, repeat the rotating 
procedure until NORMAL is shown.
