My 2007 jeep grand cherokee starts,all the signals flash constant on dash,will hardly move in drive ,and if you shut it off it wont restart.
I replaced module.put in a new 300.00computer that was
preprogrammed,and a new battery.still the same problem.what
Sounds like an anti thieft system failure, possibly a bad key chip.
Had key chip checked.dealer said it was fine.this was checked before all other things replaced.
There still could be a failure in the BCM body control module, It was the ECM you had replaced right?
Yes replaced the ecm.how do i check the bcm.?
The new ECM should be able to link with the BCM now and you can read it's trouble codes, unless there is a failure in the link up, and it will even tell you that.
Thank u so much.
