Inspection Procedure

NOTE:

Performing the check procedures for a long time with the shift lever in N 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. Confirm that battery voltages (PWR RESOURCE VB), pre-boost voltage (VL), and post-boost voltage (VH) in the Data List are 220V or more with the power switch on (READY), park (P) selected, and the engine stopped. 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)	50V
Difference between HV battery voltage (PWR RESOURCE VB) and post-boost voltage (VH)	70V
Difference between pre-boost voltage (VL) and post-boost voltage (VH)	90V
