Chrysler Repair Questions? Ask a Mechanic for Answers ASAP
Ok well you are looking at either 1 of three possibilities. Either the skreem module has failed. This is the security module for the vehicle and if it fails it will not allow the vehicle to crank over. This has to be replaced by a dealer as it has to be programed with a factory scan tool when replaced for it to work. Second is the PCM has failed. This is rare but can happen. That also has to be replaced by a dealer and programed with a factory scan tool as well. Third is the relay module which house all they relays under the hood.
To verify failure of any of these you need access to a factory scan tool so you can view the data stream going to each of these modules. Then for the relay module you also need a scan tool so you can check all the inputs to it with a DMM and scan tool by activating each circuit with the scan tool. Its a very timely process to find out which one it is and is best to take it to the dealer to verify this for you
