Diagnostic port malfunction 05 KJ CRD
Can access only PCM through diagnostic port. Been ok for 10 years when all modules were listed and accessible. Takes a long time to log in compared to past performance. Cleaned the earth connection below the power distribution centre and all modules came up initially on the screen. Accessed the PCM and then all the other modules disappeared again leaving the PCM as the only one. Suspect the front control module. Any clues?
