DTC P1552 Infiniti

Description

DTC B10C0 is set if there is a short circuit in the interior temperature sensor input circuit. The A C-ECU, the interior temperature sensor, or connector(s) or wiring between the two may be defective. Past trouble: If DTC B10C0 or B10C1 is stored as a past trouble, carry out diagnosis with particular emphasis on wiring and connector(s) between the A C-ECU and the interior temperature sensor. If the connectors and wiring are normal, and obviously the ECU is the cause of the trouble, replace the ECU. If in doubt, do not replace the ECU.
