B2109 STEERING LOCK RELAY
DescriptionINFOID:0000000003815041
The steering lock relay ON signal is transmitted to IPDM E/R by BCM via CAN communication.
IPDM E/R turns the steering lock relay ON and transmits the release of the steering to BCM.
DTC LogicINFOID:0000000003815042
DTC DETECTION LOGIC
NOTE:
 If DTC B2109 is displayed with DTC U1000, first perform the trouble diagnosis for DTC U1000. Refer to
SEC-28, "
IPDM E/R : DTC Logic".
 When IPDM E/R power supply voltage is low (Approx. 7 - 8 V for about 1 second), the DTC B2109 may be
detected.
DTC CONFIRMATION PROCEDURE
1.PERFORM DTC CONFIRMATION PROCEDURE
1. Press the push-button ignition switch under the following conditions and wait for at least 1 second.
- Selector lever is in the P or N position.
- Do not depress brake pedal.
2. Check “Self diagnostic result” with CONSULT-III.
Is DTC detected?
YES >> Go to SEC-97, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000003815043
1.CHECK POWER SUPPLY CIRCUIT
Check IPDM E/R power supply circuit. Refer to PCS-19, "
Diagnosis Procedure".
Is the circuit normal?
YES >> GO TO 2.
NO >> Repair or replace the malfunctioning part.
2.CHECK FUSE
1. Turn ignition switch OFF.
2. Check 10A fuse (No. 48, located in IPDM E/R).
Is the inspection normal?
YES >> Replace IPDM E/R. Refer to PCS-34, "Removal and Installation".
NO >> Check the following.
 Harness for open or short between IPDM E/R and battery

B210A STEERING LOCK CONDITION SWITCH
DescriptionINFOID:0000000003815044
There are 2 switches in the steering lock unit. IPDM E/R compares those 2 switches conditions to judge the
present steering status and transmit the result to BCM via CAN communication.
