HIGH FLASHER OPERATION
BCM detects the turn signal lamp circuit status by the current value.
BCM increases the turn signal lamp blinking speed if the bulb or harness open is detected with the turn signal
lamp operating.
NOTE:
The blinking speed is normal while activating the hazard warning lamp.
DTC Inspection Priority Chart
INFOID:0000000003941299
If some DTCs are displayed at the same time, perform inspections one by one based on the following priority
chart.
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 steering lock
When the following steering lock conditions agree
• BCM steering lock control status
• Steering lock condition No. 1 signal status
• Steering 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 steering lock
When any of the following conditions is fulfilled
• Steering lock unit status signal (CAN) is received normally
• The BCM steering lock control status matches the steering lock
status recognized by the steering 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 steering lock unit power supply output control in-
side BCM becomes normal
B261E: VEHICLE TYPE
Inhibit engine cranking
BCM initialization
B26E1: ENG STATE NO RES
Inhibit engine cranking
When any of the following conditions is fulfilled
• Power position changes to ACC
• Receives engine status signal (CAN)
B26E9: S/L STATUS
• Inhibit engine cranking
• Inhibit steering lock
When BCM transmits the LOCK request signal to steering lock unit,
and receives LOCK response signal from steering lock unit, the fol-
lowing conditions is fulfilled
• Steering condition No. 1 signal: LOCK (0 V)
• Steering condition No. 2 signal: LOCK (Battery voltage)
