DIAGNOSIS CODE PROCEDURES

Code No.P0504: Malfunction of the Stop Lamp Switch System.

OPERATION

• For the stop lamp switch, two switches, a stop

lamp switch for the stop lamp illumination and a
brake switch exclusively for the cruise control
system, are incorporated to improve the reliabil-
ity.

• As for the stop lamp switch, when the brake

pedal is depressed/released, the stop lamp
switch ON/OFF signal is transmitted from the
ETACS-ECU to the engine-ECU via CAN bus
line.

• As for the brake switch, the engine-ECU connec-

tor terminal BRK monitor the state of the brake
switch. The brake switch turn ON/OFF when the
brake pedal is depressed/released, and the input
signal to the engine-ECU connector terminal BRK
changes. According to this change, the
engine-ECU judges the state of the brake switch.

DIAGNOSIS CODE SET CONDITIONS

Check Condition

• The cruise control indicator lamp illuminates

<standard meter> or the cruise control display
screen is displayed <high contrast meter>.

Judgement Criteria

• Open/short in stop lamp switch circuit.

• Open circuit in the brake switch circuit (between

engine-ECU connector terminal BRK and earth).

• Malfunction of CAN bus line.

PROBABLE CAUSES

• Malfunction of CAN bus system.

• Damaged harness or connector.

• Malfunction of the fuse No.14.

• Malfunction of the stop lamp switch.

• Malfunction of the ETACS-ECU.

• Malfunction of the engine-ECU.

DIAGNOSIS PROCEDURE

CAUTION

• If there is any problem in the CAN bus lines,

an incorrect diagnosis code may be set. Prior
to this diagnosis, diagnose the CAN bus
lines.

• Before replacing the ECU, ensure that the

CAN bus lines is normal.

STEP 1. Check the CAN bus system diagnosis.
Using M.U.T.-III, perform CAN bus diagnosis (Refer
to GROUP 54C

− Explanation About The M.U.T-III

Can Bus Diagnostics ).

Q: Is the check result satisfactory?

YES :

Go to Step 2.

NO :

Repair the CAN bus lines (Refer to GROUP
54C

− Troubleshooting, Can Bus Diagnostic

Table ). Then go to Step 12.

STEP 2. Check the data list.
Using M.U.T.-III, check the data list (Refer to data list
reference table

P.17-19

• Item 74: Stop lamp switch

Q: Is the check result normal?

YES :

Go to Step 6.

NO :

Go to Step 3.

STEP 3. Check the stop lamp operation.
Check the stop lamp operation.

OK:

Brake pedal depressed: Stop lamp will illumi-

nate

Brake pedal not depressed: Stop lamp does

not illuminate

Q: Is the check result normal?

YES :

Go to Step 4.

NO :

Check the stop lamp system (Refer to
GROUP 54A

− Rear Combination Lamp,

Symptom Procedures, Inspection
Procedure 2: The stop lamps do not
illuminate or go out normally ). Then go to
Step 12.

STEP 4. Check the ETACS system data list.
Using M.U.T.-III, check the ETACS system data list
(Refer to GROUP 54A

− ETACS, Troubleshooting,

data list reference table ).

• Item 290: Stop lamp switch

Q: Is the check result normal?

YES :

Go to Step 5.

then read the diagnosis code of the cruise control
system (Refer to

P.17-6

Q: Is diagnosis code No.22 set?

YES :

Replace the engine-ECU (Refer to GROUP

13A

− Engine-ECU ). Then go to Step 12.

It can be assumed that this malfunction is
intermittent (Refer to GROUP 00

− How to

Use Troubleshooting/Inspection Service
Points, How to Cope with Intermittent
Malfunction ).
