Service Air Suspension System

Anyone else seen this message? I saw it for the first time this morning after starting my 2014 JGC Limited EcoDiesel ORA II with just over 28,000 miles. I just picked if up from the dealer yesterday after they had replaced the CAT, DEF injector, and NOX sensor to correct a long-standing MIL and separate "incorrect DEF detected; see dealer" message.

The suspension seems to be operating normally, but I've made another appointment with the dealer to get it checked out. Seems like they spend more time with my vehicle than I do lately.

Re: Service Air Suspension System

I've gotten that a few times randomly. Just goes away.

Re: Service Air Suspension System

Took my 2014 JGC in for P20EE problem. They flashed updated the computer cleared the error code but caused air suspension problem and disabled cruse control! Now they have new PCM on order and will replace it later this week. Hope after that my issues are gone! But I suspect I'll get the P20EE again till they finally replace the catalyst.

Re: Service Air Suspension System

You will get that message if they dont plug in the harness on the centre console. Did the dealer remove the centre console by any chance?

Not sure, but they did the P20EE flash like Falcon had done to correct the incorrect DEF problem and replaced the CAT. Have notified the dealer about both of your replies.

This turned to be my problem as well. The flash update to fix the P20EE issue wiped the PCM clean, so my dealer ordered a new one. They received one today, but only half of the PCM was functional, so they have to order a replacement for the replacement.

Update: Replacement PCM received from another dealer. Installed and programmed. All is good (for now).

Re: Service Air Suspension System

Got the new PCM installed! Added 300 more mile to JGC this weekend 30,000 now. All codes gone no issues so far. Fingers crossed!

Re: Service Air Suspension System

I just got that same error code about a week ago. The next time I start the GC, it goes away. I will be bringing it in next Monday since I have not been in to see my friendly service guys since the Cat issue in Nov. That was fully replaced and no issues to date.

Re: Service Air Suspension System

The Service Air Suspension warning was displayed twice Thursday evening as the odometer was approaching 75,000. Hasn't been on since and the suspension is working correctly.
