Item 36: Stop lamp switch

OK: 
Brake pedal stepped down: ON
Brake pedal released: OFF

Q: Is the stop lamp switch input normal?

YES : 

This malfunction is intermittent. Refer to

.

NO : 

Go to Step 5.

STEP 5. Voltage measurement at the ABS-ECU 
connector B-03.

(1) Disconnect ABS-ECU connector B-03 and 

measure at the harness side.

(2) Depress the brake pedal to turn on the stop lamp 

switch.

(3) Measure the voltage between terminal 3 and 

earth.

OK: System voltage

Q: Is the check result normal?

YES : 

Erase the diagnosis code memory, and 

recheck if any diagnosis code sets. If 
diagnosis code No.33 set, replace the 
hydraulic unit (integrated with ABS-ECU). 
Then go to Step 7.

NO : 

Go to Step 6.

STEP 6. Check the harness wire between 
ABS-ECU connector B-03 terminal 3 and stop 
lamp switch connector C-101 terminal 1.

NOTE: 

 After inspecting ABS-ECU connector B-03, 
intermediate connectors C-16 and C-104, and stop 
lamp switch connector C-101, inspect the wire. If any 
of these connectors is damaged, repair or replace it. 
Then go to Step 7.

Q: Is the harness wire between ABS-ECU connector 

B-03 terminal 3 and stop lamp switch connector 
C-101 terminal 1 damaged?

YES : 

Repair it and then go to Step 7.

NO : 

This malfunction is intermittent. Refer to 
GROUP 00, How to Use 
Troubleshooting/Inspection Service Points

STEP 7. Check whether the diagnosis code is 
reset.

Q: Is diagnosis code No.33 set?

YES : 

Start over at Step 1.

NO : 

The procedure is complete.

35B-37

Code No.41, 42, 43, and 44: ABS Solenoid Valve inside Hydraulic Unit (Open Circuit or Short Circuit)
Code No.52: Valve Relay Problem (Stays off)
Code No.53: Motor Relay Problem (Stays off)
Code No.55: Motor System (Seized Pump Motor)

OPERATION
Power is continuously supplied to the ABS-ECU 
through fusible link number 3 to operate the solenoid 
valve and motor.

DIAGNOSIS CODE SET CONDITIONS
These codes are set if the power supply circuit of 
solenoid valve or motor is open or shorted.

PROBABLE CAUSES
The most likely causes for these diagnosis codes to 
set are:

•

Damaged wiring harness or connector

•

Malfunction of the hydraulic unit (integrated with 
ABS-ECU)

DIAGNOSIS

STEP 1. Voltage measurement at the ABS-ECU 
connector B-03.

(1) Disconnect ABS-ECU connector B-03 and 

measure at the harness side.

(2) Measure the voltage between terminal 1 and 

earth, and 19 and earth.

OK: System voltage

Q: Is the check result normal?

YES : 

Erase the diagnosis code memory, and 

recheck if any diagnosis code sets. If 
diagnosis code No.41, 42, 43, 44, 52, 53, or 
55 set, replace the hydraulic unit (integrated 
with ABS-ECU). Then go to Step 3. If 
diagnosis code No.41, 42, 43, 44, 52, 53, or 
55 is not set, an intermittent malfunction is 
suspected. Refer to GROUP 00, How to 
Use Troubleshooting/Inspection Service 
Points

.

NO : 

Go to Step 2.

STEP 2. Check the harness wires between fusible 
link number 3 and ABS-ECU connector B-03 
(terminals 1 and 19).
