hey how are you
1-the da4 flashing just telling we have a trans malfunction , when the mechanic check it did he do a scan tcm module & retrieved fault codes what were they ?
2-did he use a Honda scanner or equivalent ?
3- with a Honda scanner you can clear the fault tcm module and reset parameters but if not available to you ,we can try a master rest
that will work if the tcm module was the issue and reset itself ,but we still needed scan if the fault did not clear and you stayed in limp mode
4- can you do this Solenoid ?
Shift Solenoid Valves Test
Please also review digarms i sent you ,press on the blue link it will open the picture for you
Remove the drain plug (A), and drain the automatic transmission fluid (ATF). 2. Reinstall the drain plug with a new sealing washer (B). 3. Place the transmission jack under the transmission, and lift it up to create clearance between the transmission and front sub-frame. 4. Disconnect the shift solenoid harness connector.
5. Remove the bolt (A) securing the bracket (B) of the AFT cooler inlet line (C) on the shift solenoid valve cover (D), and remove the line bolt (E) with sealing washers (F). 6. Remove the shift solenoid valve cover, gasket (G), and dowel pins (H).
7. Remove the bolt (A), and remove the shift solenoid harness connector (B). 8. Measure shift solenoid valves resistance between the shift solenoid harness connector terminals No. 1, No. 2, No. 3, No. 5 and body ground. Shift solenoid valve A: No. 5 terminal (BLU) Shift solenoid valve B: No. 2 terminal (ORN) Shift solenoid valve C: No. 1 terminal (GRN) Shift solenoid valve E: No. 3 terminal (RED) STANDARD: 12 - 25 Ohms 9. If the resistance is out of standard, disconnect the shift solenoid valve connector, and measure its resistance at the solenoid valve connector. Replace the shift solenoid valve if the resistance is out of standard. 10. Connect the battery positive terminal to the shift solenoid harness connector terminals, and connect the battery negative terminal to body ground individually. A clicking sound should be heard. 11. If no sound is heard, connect the battery positive terminal to the shift solenoid valve connector terminal, and check the clicking sound is heard. Replace the shift solenoid valve if no sound is heard. 12. Replace the solenoid harness if the tests results are OK. 13. Install the new O-ring on the shift solenoid harness connector, and install the connector in the transmission housing. 14. Install the shift solenoid valve cover with the new gasket and dowel pins. 15. Install the ATF cooler inlet line with the line bolt and the new sealing washers. Create clearance with the jack between the transmission and the front sub-frame to tighten the line bolt with the torque wrench. 16. Install the bracket of the ATF cooler inlet line on the shift solenoid valve cover with the bolt. 17. Check the connector for rust, dirt, or oil, then connect the connector securely. 18. Remove the transmission jack. 19. Refill the transmission with the recommended fluid.
Master reset Procedure
1- Disconnect Battery Cables ( Negative & Positive Cables )you can use any electrical wire as an extension if battery cables don't reach .
2- Hold cables Together for 60 secs ,then let go
3- Wait 15 minutes
4- Make sure all doors are closed
5- Reconnect battery Cables
6- Lock & unlock the vehicles using the key from driver door side (if you have a key fob with no blade key, just lock & unlock using the key fob buttons)
7- Enter the vehicle and attempt to start
Please let me know
