DTC CONFIRMATION PROCEDURE
1. DTC CONFIRMATION
1. Erase DTC.
2. Turn ignition switch OFF.
3. Perform the Self Diagnostic Result of BCM with CO NSULT, after the ignition switch has been turned ON
for 120 seconds or more.
Is any DTC detected?
YES >> Refer to BCS-71, "Diagnosis Procedure".
NO >> Inspection End.
Diagnosis ProcedureINFOID:0000000009462037
1. CHECK BATTERY VOLTAGE
Check battery voltage.
Is battery voltage less than 8.8V?
YES >> Charge battery and retest. Refer to CHG-17, "Work Flow (With EXP-800 NI or GR8-1200 NI)" or
CHG-20, "Work Flow (Without EXP-800 NI or GR8-1200 NI)"
.
NO >> GO TO 2.
2. CHECK POWER SUPPLY AND GROUND CIRCUIT
Check BCM power supply and ground circuit. Refer to BCS-74, "Diagnosis Procedure"
.
Is the inspection result normal?
YES >> GO TO 3.
NO >> Repair or replace harness or connectors.
3. BCM SELF DIAGNOSTIC RESULT
Perform Self Diagnostic Result of BCM with CONSULT. Refer to BCS-25, "BCM : CONSULT Function (BCM -
BCM)".
Is DTC B2562 CRNT?
YES >> Replace BCM. Refer to BCS-80, "Removal and Installation".
NO >> Refer to GI-43, "Intermittent Incident"
.
CONSULT Display DTC Detection Condition Possible cause
LOW VOLTAGE
[B2562] When the power supply voltage to BCM remains less
than 8.8V for 120 seconds or more • Harness or connector (power supply circuit)
• Vehicle battery

Is any DTC detected?
YES >> Refer to BCS-72, "Diagnosis Procedure".
NO >> Inspection End.
Diagnosis ProcedureINFOID:0000000009462039
Regarding Wiring Diagram information, refer to BCS-55, "Wiring Diagram".
1. CHECK FUSE
Check that the following fuse is not blown.
Is the fuse or fusible link blown?
YES >> Replace the blown fuse after repairing the affected circuit.
NO >> GO TO 2.
2. CHECK BAT BCM FUSE CIRCUIT
1. Disconnect BCM connector M21.
2. Check voltage between BCM connector M21 terminal 131 and ground.
Is the inspection result normal?
YES >> Replace BCM. Refer to BCS-80, "Removal and Installation".
NO >> Repair or replace harness or connectors. GO TO 3.
3. CHECK BATTERY SAVER OUTPUT CIRCUIT FOR SHORT TO GROUND
1. Turn ignition OFF.
2. Check continuity between BCM connector M21 terminal 129 and ground.
