DTC Inspection Priority Chart

INFOID:0000000009467078

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

Inhibit engine cranking

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

B26E1: ENG STATE NO RECIV

Inhibit engine cranking

When any of the following conditions are fulfilled
• Power position changes to ACC
• Receives engine status signal (CAN)

NOTE:

Details of time display

• CRNT: Displays when there is a malfunction now or after returning to the normal condition until turning igni-

tion switch OFF

→ ON again.

• 1 - 39: Displayed if any previous malfunction is present when current condition is normal. It increases 1

→ 2

→ 3...38 → 39 after returning to the normal condition whenever ignition switch OFF → ON. The counter

remains at 39 even if the number of cycles exceeds it. It is counted from 1 again when turning ignition switch

OFF

→ ON after returning to the normal condition if the malfunction is detected again.
