DTC Inspection Priority Chart

INFOID:0000000010062256

If some DTCs are displayed at the same time, perform inspections one by one based on the following priority

chart.

B2562: LO VOLTAGE

Inhibit engine cranking

100 ms after the power supply voltage increases to more than 8.8 V

B2608: STARTER RELAY

Inhibit engine cranking

500 ms after the following signal communication status becomes 
consistent
• Starter motor relay control signal
• Starter relay status signal (CAN)

B260A: IGNITION RELAY

Inhibit engine cranking

500 ms after the following conditions are fulfilled
• IGN relay (IPDM E/R) control signal: OFF (Battery voltage)
• Ignition ON signal (CAN to IPDM E/R): OFF (Request signal)
• Ignition ON signal (CAN from IPDM E/R): OFF (Condition signal)

1 second after the starter motor relay control inside BCM becomes 
normal

B2618: BCM

Inhibit engine cranking

1 second after the ignition relay (IPDM E/R) control inside BCM be-
comes normal
