2. Clear the DTC with the HDS.  

3. Start the engine. Hold the engine speed at 3,000 rpm without load (in Park or neutral) until the radiator 

fan comes on, then let it idle.  

4. Test-drive under these conditions: 



Engine coolant temperature (ECT SENSOR 1) above 158°F (70°C)  



A/T in D position (M/T in 3rd gear)  



Vehicle speed between 25-55 mph (40 - 88 km/h) for 5 minutes  



Drive at a steady speed between 55-75 mph (88-120 km/h) for 10 seconds, then decelerate (with the 
throttle fully closed) for 4 seconds  

5. Monitor the OBD STATUS for DTC P2A00 in the DTCs MENU with the HDS. 

Does the screen indicate FAILED?  

YES -Go to step 6. 

NO -If the screen indicates PASSED, intermittent failure, the system is OK at this time. Check for poor 
connections or loose terminals at the A/F sensor (Sensor 1) and the ECM/PCM. If the screen indicates 
EXECUTING, keep driving until a result comes on. If the screen indicates OUT OF CONDITION, go to 
step 3 and recheck. 

6. Turn the ignition switch OFF.  

7. Replace the A/F sensor (Sensor 1) (see A/F SENSOR REPLACEMENT ).  

8. Turn the ignition switch ON (II).  

9. Reset the ECM/PCM with the HDS.  

10. Do the ECM/PCM idle learn procedure (see ECM/PCM IDLE LEARN PROCEDURE ).  

11. Start the engine. Hold the engine speed at 3,000 rpm without load (in Park or neutral) until the radiator 

fan comes on, then let it idle.  

12. Test-drive under these conditions: 



Engine coolant temperature (ECT SENSOR 1) above 158°F (70°C)  



A/T in D position (M/T in 3rd gear)  



Vehicle speed between 25-55 mph (40- 88 km/h) for 5 minutes  



Drive at a steady speed between 55-75 mph (88-120 km/h) for 10 seconds, then decelerate (with the 
throttle fully closed) for 4 seconds  

13. Check for Temporary DTCs or DTCs with the HDS. 

Is DTC P2A00 indicated?  

YES -Check for poor connections or loose terminals at the A/F sensor (Sensor 1) and the ECM/PCM, 
then go to step 1. 

NO -Go to step 14.

14. Monitor the OBD STATUS for DTC P2A00 in the DTCs MENU with the HDS. 

Does the screen indicate PASSED?  

YES -Troubleshooting is complete. If any other Temporary DTCs or DTCs were indicated in step 13, go 
to the INDICATED DTCS TROUBLESHOOTING. 

NO -If the screen indicates FAILED, check for poor connections or loose terminals at the A/F sensor 
(Sensor 1) and the ECM/PCM, then go to step 1. If the screen indicates EXECUTING, keep driving until 
a result comes on. If the screen indicates OUT OF CONDITION, go to step 11. 

DTC U0028: F-CAN MALFUNCTION (BUS-OFF) 

1. Turn the ignition switch ON (II).  

2. Clear the DTC with the HDS.  

3. Check for Temporary DTCs or DTCs with the HDS. 

Is DTC U0028 indicated?  

YES -Update the ECM/PCM if it does not have the latest software (see UPDATING THE ECM/PCM ), 
or substitute a known-good ECM/PCM (see SUBSTITUTING THE ECM/PCM ), then recheck. If the 
symptom/indication goes away with a known-good ECM/PCM, replace the original ECM/PCM (see 
ECM/PCM REPLACEMENT ). 

NO -Intermittent failure, the system is OK at this time. If any other Temporary DTCs or DTCs are 
indicated, go to the INDICATED DTCS TROUBLESHOOTING. 

DTC U0122: F-CAN MALFUNCTION (ECM/PCM-VSA MODULATOR-CONTROL UNIT) 

1. Turn the ignition switch ON (II).  

2. Clear the DTC with the HDS.  

3. Check for Temporary DTCs or DTCs with the HDS. 

Is DTC U0122 indicated?  

YES -Go to step 4.
