1998 Mitsubishi Eclipse 4 cyl Automatic 112 miles

I had my transmission redone and my sensors replaced I recently changed the battery cables on my car and my engine light is on, went to get my emissions done and they told me I most likely needed to get my check engine light reset ( cleared codes) from memory, but I need to take it to the dealer. Need Advice Please, In Georgia

Follow the link at the bottom of this text, it will take you to a page where you can buy a scantool to shut the light off, at a cheaper price than the dealer visit!

Hi there,

All codes will be cleared after removing battery neg (-) cable for 10 sec, if codes re set, get a scan done to identify code I.D's.

What you have for codes all related to a tranny and or wiring
when disconnected the battery memory should erase
I would check with the tranny shop for more help

DTC 1784: LOW-REVERSE PRESSURE SWITCH
1. Remove transaxle relay from connector. Turn ignition on. Install scan tool and observe low-reverse pressure switch condition. Apply battery voltage to transaxle relay connector terminal No. 8. If low-reverse pressure switch stays off, go to next step. If low-reverse pressure switch turns on, go to step 4.

2. Raise vehicle enough to allow drive wheels to spin freely. Test low-reverse clutch hydraulic pressure. See HYDRAULIC PRESSURE TESTS under TESTING. If low-reverse clutch pressure test is not within specification, internal transaxle failure exists. If low-reverse clutch pressure test is within specification, observe scan tool.

3. If low-reverse pressure switch turns on, trouble code is intermittent. Check wire harnesses and connectors for damage or poor connection. If low-reverse pressure switch does not turn on, replace solenoid and pressure switch assembly. Recheck trouble codes. If trouble code resets, replace TCM.

4. Check and repair wiring harness between transaxle relay connector and solenoid and pressure switch assembly connector. If wiring harness is okay, check wire between TCM connector terminal No. 10 and solenoid and pressure switch assembly.

5. If wire between TCM connector terminal No. 10 and solenoid and pressure switch assembly is okay, check TCM and solenoid and pressure switch assembly connectors. Repair connectors as necessary. If connectors are okay, recheck trouble codes. If trouble code resets, replace solenoid and pressure switch assembly. Recheck trouble codes. If trouble code resets, replace TCM.

DTC P1775 sets when 3 unsuccessful attempts to shift into 1st gear occur. Internal transaxle failure may exist including shift solenoid valve sticking or solenoid malfunction
