Condition
Some dealerships may comment that after a module is replaced and programmed,
the odometer may display zero miles or the incorrect mileage. This condition maybe
accompanied with any of the following current DTC's: U1973, U197E, U197F, U2A90,
U2A91, U1978, and/or U197F.
NOTE: In some cases, these DTC's will not be set.
Cause
This condition may be caused if the VIN or mileage fails to write to the odometer.
Correction:
If you experience this condition, do NOT replace any further modules or swap any modules from a like vehicle as
this can make it more di cult to repair the condition.
If unnecessary module replacement or module swapping is found, the repairs may not be covered under
warranty.
To correct this condition:
- If a module was replaced, make sure all programming, setup, learns, etc. have been completed, per SI
procedures. There have been cases where the BCM was replaced and the BCM setup was never completed,
which caused this concern.
- If the above items do not correct the concern, then engineering will need to be involved. Please create a case
with the Technical Assistance Center (TAC) and document the issue including: customer's original issue, any
part(s) replaced, programming error codes, current DTC's, what the odometer displays, this PI number and any
additional details. TAC will engage engineering to correct this concern.
NOTE: If DTC U197F is set on a vehicle where a module was NOT replaced and the IPC does not display the
correct mileage, then perform a short test drive (1 to 2 miles) and verify the mileage now reads correct and the
DTC clears.
