DTC Inspection Priority Chart

INFOID:0000000004494661

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

chart.

B2607: S/L RELAY

Inhibit engine cranking

500 ms after the following CAN signal communication status has
become consistent
• Electronic steering column lock relay signal (Request signal)
• Electronic steering column lock relay signal (Condition signal)

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)

B2609: S/L STATUS

• Inhibit engine cranking
• Inhibit electronic steering

column lock

When the following electronic steering column lock conditions
agree
• BCM electronic steering column lock control status
• Electronic steering column lock condition No. 1 signal status
• Electronic steering column lock condition No. 2 signal status

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)

B2612: S/L STATUS

• Inhibit engine cranking
• Inhibit electronic steering

column lock

When any of the following conditions is fulfilled
• Electronic steering column lock unit status signal (CAN) is re-

ceived normally

• The BCM electronic steering column lock control status matches

the electronic steering column lock status recognized by the
electronic steering column lock unit status signal (CAN from
IPDM E/R)

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

B2619: BCM

Inhibit engine cranking

1 second after the electronic steering column lock unit power sup-
ply output control inside BCM becomes normal

B261E: VEHICLE TYPE

Inhibit engine cranking

BCM initialization

B26E1: ENG STATE NO RECIV

Inhibit engine cranking

When any of the following conditions is 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 like 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.
