DTC Inspection Priority Chart
INFOID:0000000010057373
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)
B260F: ENG STATE SIG LOST
Maintains the power supply
position attained at the time
of DTC detection
When any of the following conditions is fulfilled
• Power position changes to ACC
• Receives engine status signal (CAN)
B2617: STARTER RELAY CIRC
