ENTRY AND START SYSTEM(for Start Function), Diagnostic DTC:B2286 and P0335

DTC Code DTC Name
B2286 Runnable Signal Malfunction
P0335 Crankshaft Position Sensor Circuit Malfunction (NE Signal)

DESCRIPTION

The power management control ECU and ECM are connected by a cable and the CAN communication lines. These DTCs are stored when the cable information of the crankshaft position sensor signal and CAN information of the crankshaft position sensor signal are inconsistent.

Tip:

When the power management control ECU is replaced with a new one and the cable is connected to the negative (-) battery terminal, the power source mode is reset to on (IG). When the battery is removed and reinstalled, the power source mode that was selected when the battery was removed is restored.

CAUTION / NOTICE / HINT

Note:

  • When using the intelligent tester with the engine switch off to troubleshoot: Connect the intelligent tester to the vehicle, and turn a courtesy light switch on and off at 1.5 second intervals until communication between the intelligent tester and vehicle begins.

  • Before performing the inspection, check that there are no problems related to the CAN communication system and LIN communication system.

  • Inspect the fuses for circuits related to this system before performing the following inspection procedure.

PROCEDURE

  1. CHECK HARNESS AND CONNECTOR (BATTERY - POWER MANAGEMENT CONTROL ECU)
