P0702 p1685 fault code on 2.7crd merc transmission
DTC P0702 - Transmission Control System Electrical
There is a code in the ****** control module and need to check harnesses and wiring, as first step.
DTC P1685 - Skim Invalid Key
Transponder ID (in ignition key) is monitored with ignition on. DTC will set if transponder ID read by Smart Key Immobilizer Module (SKIM) does not match any transponder ID's stored in SKIM memory. Possible Causes:
- Incorrect VIN In PCM
- Invalid SKIM Key Present
- No Communication With SKIM
- No VIN Programmed In The PCM
- PCM SKIM Trouble Codes Set
I would suggest clearing all these codes, and drive it until the problem
arises again, or the check engine light comes on, and then check for
codes again. To clear the codes you will need to remove the negative
battery cable, and touch it to the positive cable, for about 15 seconds.
Then re hook and all the modules will be reset. If this isnt work, visit your Trans Service.
Hope this helps; also keep in mind that your feedback is important and I'll appreciate
your time and consideration if you leave some testimonial comment about
