P1750(46) : D-Blinks : MIL-Off : Mechanical problem in hydraulic systemMother-in-law got a DTC D-light code of 46.
Does anybody have the OEM shop manual for the 2003-2004 Pilot. I cannot find this code anywhere else. If you do have this book, turn to the beginning of the Automatic-Transmission section. Then find the sub-section marked "DTC Troubleshooting Index". It should be within the first few pages of the Automatic-Transmission section. The blink codes are shown next to the "P" codes inside parentheses....ie: Pxxxx (46-1)
If there is more than one code 46 (46-1 46-2 46-3), please let me know what each of them is described as.
Thanks so much for anyone's help!
I know, but wondering if anyone could watch the video and tell me if those are slow or fast flashes. I looked at the 09-10 repair manual and read that one long flash is equivalent to 10 short ones, so these might all be short ones. If so, what is code 04?If it's 4 slow, then it's code 40. If it's two slow two fast, it's code 22.
TL Manual DTC P0741 (blink code 40) said:1- warm up the engine.
2- Check to be sure the trans is filled to the proper level and check for fluid leaks.
3- Drain ATF through a paint strainer. Look for contamination (small pieces of metal or friction material) in the strainer. NOTE: If little or no contamination is found in the strainer, the ATF is OK. Discoloration, small chips or flakes, metal fuzz and slightly "burnt" smell is considered normal. Is the ATF OK? YES- Replace the ATF then go to step 4. No- Repair or replace the transmission.
4- Clear the DTC (code) with the HDS (you probably can't do this).
5- Select LOCKUP SOL TEST in MISCELLANEOUS TEST MENU, then carry out AT LOCKUP SOL A test in LOCKUP SOL TEST MENU with the HDS. Is a clicking sound heard? Yes- Go to step 6. No- Replace torque converter clutch solenoid valve then go to step 10.
6- Select LINEAR SOL TEST in MISCELLANEOUS TEST MENU, then carry out LINEAR SOL C TEST in LINEAR SOL TEST MENU. Is the system OK? Yes- Go to step 7. No- Follow instructions indicated on the HDS by the tester result. Got to step 10 if any part was replaced.
7- Run the engine until the engine coolant temp reaches 176*F.
8- Test-drive the vehicle at 55mph for 2 minutes while monitoring the vehicle speed with the HDS.
9- Check the OBD STATUS in DTCs MENU for a pass/fail test of code P0741. Did the result indicate a fail? Yes- repair or replace the transmission. No- Intermittent failure, the system is OK at this time. If the tester indicates NOT COMPLETE, return to step 8 and recheck.
10- Clear the DTC with the HDS.
11. Test-drive the vehicle for several minutes under the same conditions as those indicated by the freeze data.
12. Check the OBD STATUS in DTCs. MENU for a pass fail test of code P0741. YES- The problem has been corrected. NO- Return to step 1 and recheck.
