PHIGH 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 ChartINFOID:0000000003959693
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 cranking500 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 lockWhen 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 cranking500 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 LOSTMaintains the power supply
position attained at the time
of DTC detectionWhen 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 lockWhen 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 cranking1 second after the starter motor relay control inside BCM becomes
normal
B2618: BCM Inhibit engine cranking1 second after the ignition relay (IPDM E/R) control inside BCM be-
comes normal
B2619: BCM Inhibit engine cranking1 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 crankingWhen 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 lockWhen 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
