Honda Element. Manual - part 588

11. Monitor the OBD STATUS for DTC P0507 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 10, go 
to the indicated DTCs troubleshooting. 

NO - If the screen indicates FAILED, go to step 12. If the screen indicates EXECUTING keep idling 
until a result comes on. If the screen indicates OUT OF CONDITION, recheck with different load 
conditions (turn on the headlights, blower motor, or A/C; change the gear position, etc.), then go to step 9.

12. 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 ).  

13. 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.  

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

Is DTC P0507 indicated?  

YES - Check for poor connections or loose terminals at the throttle body and the ECM/PCM. If the 
ECM/PCM was updated, substitute a known-good ECM/PCM (see SUBSTITUTING THE 
ECM/PCM ), then go to step 13. If the ECM/PCM was substituted, go to step 1. 

NO - Go to step 15. 

15. Monitor the OBD STATUS for DTC P0507 in the DTCs MENU with the HDS. 

Does the screen indicate PASSED?  

YES - If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted, 
replace the original ECM/PCM (see ECM/PCM REPLACEMENT ): If any other Temporary DTCs or 
DTCs were indicated in step 14, go to the indicated DTCs troubleshooting. 

NO - If the screen indicates FAILED, check for poor connections or loose terminals at the throttle body 
and the ECM/PCM. If the ECM/PCM was updated, substitute a known-good ECM/PCM (see 
SUBSTITUTING THE ECM/PCM ), then go to step 13. If the ECM/PCM was substituted, go to step 1. 
If the screen indicates EXECUTING, keep idling until a result comes on. If the screen indicates OUT OF 
CONDITION, go to step 13. 

A/C SIGNAL CIRCUIT TROUBLESHOOTING 

1. Start the engine.  

2. Turn the blower switch on.  

3. Turn the A/C switch on.  

4. Check the A/C CLUTCH in the DATA LIST with the HDS.

Does it indicated ON?  

YES - Go to step 5. 

NO - Do the A/C system test (see A/C SYSTEM TEST ). 

5. Check the A/C system. 

Does the A/C system operate?  

YES - The air conditioning system circuit is OK. 

NO - Go to step 6. 

6. Turn the ignition switch OFF.  

7. Turn the ignition switch ON (II).  

8. Activate the A/C CLUTCH in the INSPECTION MENU with the HDS. 

Is there a clicking noise from the A/C compressor clutch?  

YES - Do the A/C system test (see A/C SYSTEM TEST ). 

NO - Go to step 9. 

9. Momentarily connect under-hood fuse/relay box 14P connector terminal No. 10 to body ground with a 

jumper wire several times.

Is there a clicking noise from the A/C compressor clutch?  

YES - Repair open in the wire between the ECM/PCM (E18) and the A/C clutch relay. 

NO - 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 ). 

ALTERNATOR FR SIGNAL CIRCUIT TROUBLESHOOTING 

1. Start the engine, and let it idle.  

2. Monitor the ALTERNATOR in the DATA LIST with the HDS.  

3. Check if the indicated percentage varies when the headlight switch is turned on. 

Does the percentage vary?  

YES - The alternator signal circuit is OK. 

NO - Go to step 4. 

4. Turn the headlight switch and ignition switch OFF.  

5. Jump the SCS line with the HDS.  

6. Disconnect the alternator 4P connector.  

7. Disconnect ECM/PCM connector B (24P).  

8. Check for continuity between body ground and ECM/PCM connector terminal B13.

Is there continuity?  

YES - Repair short in the wire between the ECM/PCM (B13) and the alternator. 

NO - 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 ).

PSP SWITCH SIGNAL CIRCUIT TROUBLESHOOTING

1. Start the engine, and let it idle.  

2. Align the steering wheel straight ahead.  

3. Check the PSP SWITCH in the DATA LIST with the HDS. 

Does it indicate ON?  

YES - Go to step 4. 

NO - Go to step 14. 

4. Turn the steering wheel to the full lock position.  

5. Check the PSP SWITCH in the DATA LIST with the HDS. 

Does it change to OFF?  

YES - The PSP switch signal circuit is OK. 

NO - Go to step 6. 

6. Turn the ignition switch OFF.  

7. Disconnect the PSP switch 2P connector.  

8. Start the engine.  

9. Check the PSP SWITCH in the DATA LIST with the HDS. 

Does it change to OFF?  

YES - Replace the PSP switch (see POWER STEERING HOSE, LINE, AND PRESSURE SWITCH 
REPLACEMENT ). 

NO - Go to step 10. 

10. Turn the ignition switch OFF.  

11. Jump the SCS line with the HDS.  

12. Disconnect ECM/PCM connector E (31P).  

13. Check for continuity between PSP switch 2P connector terminal No. 1 and body ground.
