I bought my 2004 Sprinter in December 2016. My CEL is on and have these 3 codes:
U0423 = Invalid Data Received From Instrument Panel Cluster Control Module
P1926 = The P1926 SLA (shifter module) fault code (Ignore for Sprinter??)
2822 = (stored event) Engine off time
These codes came from Mercedes. My OBD reader only sees the U0423
I did have the famous trans adapter leak that soaked the TCU under the drivers seat. This has been repaired and I cleaned the connections and the TCU with contact cleaner. It never had any shifting problems. Could the TCU be bad and causing this?
Mercedes wants to replace the shifting parts for $1,200 and will not guaranty the problem will be resolved. Could this be the issue? (They also claimed they are disadvantaged because Dodge does not provide them with a wiring diagram. I will not return there.)
I have driven 5,000 miles and have no driving or operating symptoms, other than these 2:
1. The check engine light comes back on after a reset.
2. The odometer light comes back on after the normal 30+- second timeout. But is corrected by turning the key on and off.
I was just reading about a recall that updates the ECU and may cause at least some of the symptoms I have. I don't know the history of the rig before I bought it 12/2016.
to make things worse, I live in California and have 11 months before I need to get a smog check.
Any help appreciated.
