4. Is the measured current data within specifications? 

YES  

Go to step 2. 

NO  

Substitute with a known-good multifunction switch and check for proper operation. If the problem 
is corrected, replace multifunction switch and then go to "VERIFICATION OF VEHICLE 
REPAIR" procedure. 

2. Check IPM 

1. Connect scan tool to Data Link Connector (DLC).  

2. Ignition "ON" & engine "OFF".  

3. Substitute with a known-good IPM and Check if the DTC is erased.  

4. Is the DTC erased? 

YES  

Substitute with a known-good IPM and check for proper operation. 

If the problem is corrected, replace IPM and then go to "VERIFICATION OF VEHICLE 
REPAIR" procedure. 

NO
