B2110 PNP/CLUTCH INTERLOCK SWITCH

Description

INFOID:0000000004206126

IPDM E/R confirms the shift position with the following signals.

• Park/neutral position (PNP) switch (CVT models)

• Clutch inter lock switch (M/T models)

• Shift position signal from BCM (CAN)

DTC Logic

INFOID:0000000004206127

DTC DETECTION LOGIC

NOTE:

• If DTC B2110 is displayed with DTC U1000, first perform the trouble diagnosis for DTC U1000. Refer to
