DTCs U0111 And U1897 After 07141 BECM Reprogram - keywords BAS battery BECM BDU cal calibrate calibration campaign DTC ECM engine hybrid lamp LAT light PCM recalibrate recalibration reflash SES

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

On rare occasions, DTCs U0111 and U1897 may be experienced shortly after the BECM is reprogrammed. Typically, this occurs when performing service policy 07141 and reprogramming the BECM. This may occur if the vehicle required two BECM programming events but only one BECM programming event was completed.

If DTCs U0111 and U1897 occur shortly after programming the BECM, review 07141 again and determine if two BECM programming events should have been performed.

If two programming events were required, the following two selections would have been displayed on the Supported Controller Screen of TIS 2 Web:

BECM Hybrid Battery Voltage Correction

BECM Hybrid Battery Software Enhancement

If both of these selections were displayed, but only one of them were completed by the technician, perform both BECM programming events as outlined in 07141 and re-evaluate the concern. If both programming events were not necessary, or if this concern is still present after performing both programming events, perform the SI diagnostics for these DTCs and repair as necessary.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
