Inspection Procedure

NOTE:

Performing the check procedures for a long time with the shift lever in the N position may cause DTC P3000-388 to be set.

HINT:

If, after performing troubleshooting, it is necessary to replace the battery smart unit, voltages need to be confirmed after installing the new battery smart unit. To confirm normal operation, compare the HV battery voltage (PWR RESOURCE VB), pre-boost voltage (VL), and post-boost voltage (VH) in the data list with the power switch on (READY) and the shift lever in the N position. When the system is normal, the PWR RESOURCE VB, VL, and VH values should be almost equal (voltage boosting will not occur when the shift lever is in neutral). If the difference between each voltage exceeds the values specified below, there is a malfunction in the battery smart unit.

Inspection voltage	Maximum voltage difference
Difference between HV battery voltage (PWR RESOURCE VB) and pre-boost voltage (VL)	50 V
Difference between HV battery voltage (PWR RESOURCE VB) and post-boost voltage (VH)	70 V
Difference between pre-boost voltage (VL) and post-boost voltage (VH)	70 V
