Diagnosis Procedure

1. Turn ignition switch OFF.
2. Disconnect BCM connector.
3. Check voltage between BCM harness connector and ground.

   (+)		(-)	Voltage (V) (Approx.)
   BCM
   Connector	Terminal
   M123	105	Ground	Battery voltage

   Is the inspection normal? 

   YES: GO TO 2.

   NO-1: Check 10 A fuse [No. 7, located in the fuse block (J/B)].

   NO-2: Check harness for open or short between BCM and fuse.

1. Disconnect stop lamp switch connector.
2. Check voltage between stop lamp switch harness connector and ground.

   (+)		(-)	Voltage (V) (Approx.)
   Stop lamp switch
   Connector	Terminal
   E110	1	Ground	Battery voltage

   Is the inspection result normal? 

   YES: GO TO 3.

   NO: Check harness for open or short between stop lamp switch and fuse.

1. Connect stop lamp switch connector.
2. Check voltage between BCM harness connector and ground.

   (+)		(-)	Condition		Voltage (V) (Approx.)
   BCM
   Connector	Terminal
   M120	9	Ground	Brake pedal	Depressed	Battery voltage
   				Not depressed	0

   Is the inspecting result normal? 

   YES: GO TO 4.

   NO: GO TO  5.

1. Replace BCM. Refer to "REMOVAL AND INSTALLATION ".
2. Perform initialization of BCM and registration of all Intelligent Keys using CONSULT.

1. Disconnect stop lamp switch connector.
2. Check continuity between stop lamp switch harness connector and BCM harness connector.

   Stop lamp switch		BCM		Continuity
   Connector	Terminal	Connector	Terminal
   E110	2	M120	9	Existed

3. Check continuity between stop lamp switch harness connector and ground.

   Stop lamp switch		Ground	Continuity
   Connector	Terminal
   E110	2		Not existed

   Is the inspection result normal? 

   YES: GO TO 6.

   NO: Repair or replace harness.

Refer to "COMPONENT INSPECTION ".

Is the inspection result normal? 

YES: GO TO 7.

NO: Replace stop lamp switch. Refer to "REMOVAL AND INSTALLATION ".

Refer to "INTERMITTENT INCIDENT ".
