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 difficult 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, YOU MUST make sure all programming, SETUPs, learns, etc.
have been completed, per SI procedures. There have been MANY cases where a module
was replaced and the SETUP PROCEDURE WAS NEVER completed, which WILL cause this
concern and delay the repair of the vehicle. MAKE SURE THE SETUP PROCEDURE IS
COMPLETED FOR THE MODULE REPLACED.
- 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. Typically, this DTC U197F can set if the
battery was disconnected or there was a low battery voltage condition.
- If DTC U1978 is set, then reprogramming the IPC will typically correct this concern. Try
to reprogram the IPC using TLC/SPS. If the IPC already has the most current cals, then
contact Techline Customer Support Center (TCSC) and provide this PI document. Let them
know you have DTC U1978 and need to reprogram the IPC with the same cals to correct
this condition per this PI.
- 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.
