B2623 INSIDE ANTENNA

2.

CHECK INSIDE KEY ANTENNA CIRCUIT

1. Disconnect BCM connector and inside key antenna (luggage room) connector.

2. Check continuity between BCM harness connector and inside key antenna (luggage room) harness con-

nector.

3. Check continuity between BCM harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair or replace harness.

3.

CHECK INSIDE KEY ANTENNA INPUT SIGNAL 2

1. Replace inside key antenna (luggage room). (New antenna or other antenna)

2. Connect BCM connector and inside key antenna (luggage room) connector.

3. Check signal between BCM harness connector and ground using oscilloscope.

Is the inspection result normal?

YES

>> Replace inside key antenna (luggage room). Refer to 

DLK-315, "LUGGAGE ROOM : Removal

and Installation"

.

NO

>> Replace BCM. Refer to 

BCS-80, "Removal and Installation"

.

>> Shift lock solenoid is OK.

Diagnosis Procedure

INFOID:0000000009175695

Regarding Wiring Diagram information, refer to 

TM-74, "Wiring diagram"

.

1.

 CHECK POWER SOURCE (STOP LAMP SWITCH)

1. Turn ignition switch OFF.

2. Disconnect stop lamp switch connector.

3. Check voltage between stop lamp switch connector E38 terminal 1 and ground.

Is the inspection result normal?

YES

>> GO TO 2. 

NO

>> Check the following:

• Harness for short or open between fuse block (J/B) and stop lamp switch

• 10A fuse (No. 10, located in fuse block [J/B])

2.

CHECK STOP LAMP SWITCH

Check stop lamp switch. Refer to 

TM-179, "Component Inspection (Stop Lamp Switch)"

.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Replace stop lamp switch. Refer to 

BR-20, "Exploded View"

.

3.

CHECK GROUND CIRCUIT (STOP LAMP RELAY)

1. Remove the stop lamp relay.

2. Check continuity between stop lamp relay connector E39 terminal 2 and ground.
