TECHNICAL DESCRIPTION (COMMENT)

The parking brake switch turns on and off by operat-
ing the parking brake lever, and the brake warning 
light illuminates and goes out, indicating the operat-
ing status of parking brake to a driver.

.

TROUBLESHOOTING HINTS (THE MOST 
LIKELY CAUSES FOR THIS CASE:) 

• Damaged wiring harness or connector

• Parking brake switch defective

• Combination meter defective 

.

DIAGNOSIS

Required Special Tools:

• MB991958: Scan Tool (M.U.T.-III Sub Assembly)

• MB991824: Vehicle Communication Interface (V.C.I.)

• MB991827: M.U.T.-III USB Cable

• MB991910: M.U.T.-III Main Harness A

STEP 1. Using scan tool MB991958, check combination 
meter actuator test.

CAUTION

To prevent damage to scan tool MB991958, always turn the 
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958. 
(1) Connect scan tool MB991958 to the data link connector.
(2) Turn the ignition switch to the "ON" position.
(3) Turn the parking brake switch and brake fluid level switch to 

"OFF" position.

(4) Set scan tool MB991958 to the actuator test mode.

• Item 13: Indicator4: ON

• The brake warning light illuminates.

• Item 13: Indicator4: OFF

• The brake warning light goes out.

(5) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the check result normal?

YES : Go to Step 2.
NO :  Replace the combination meter (Refer to GROUP 

54A, Combination meter assembly 

P.54A-118

).

STEP 2. Check the parking brake switch.
Refer to 

P.36-10

.

Q: Is the parking brake switch normal?

YES : Go to Step 3.
NO :  Replace the parking brake switch (Refer to 

P.36-11

). 

Then go to Step 6.

STEP 3. Connector check: D-125 parking brake switch 
connector, C-22 intermediate connector and C-03 
combination meter connector
Q: Is the check result normal?

YES : Go to Step 4.
NO :  Repair or replace the faulty connector (Refer to 

GROUP 00E, Harness Connector Inspection 

P.00E-2

). Then go to Step 6.

STEP 4. Check the wiring harness for an open circuit 
between D-125 parking brake switch connector terminal 
No.1 and C-03 combination meter connector terminal No.4. 
(1) Disconnect D-125 parking brake switch connector from 

C-03 combination meter connector, and measure at the 
wiring harness side connector.

(2) Measure the resistance between D-125 parking brake 

switch connector terminal No.1 and C-03 combination 
meter connector terminal No.4.

OK: Continuity exists (2 

Ω or less)

Q: Is the check result normal?

YES : Go to Step 5.
NO :  A open circuit may be present in the wiring harness 

between D-125 parking brake switch connector 
terminal No.1 and C-03 combination meter connector 
terminal No.4. Repair the wiring harness if necessary, 
and then go to Step 6.

STEP 5. Retest the system.
Q: Does the brake warning light illuminate when the 

parking brake lever is pull?
YES : 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 

P.00-15

).

NO :  Replace the combination meter (Refer to GROUP 

54A, Combination meter assembly 

P.54A-118

).

STEP 6. Retest the system.
Q: Does the brake warning light illuminate when the 

parking brake lever is pulled?
YES : The procedure is complete.
NO :  Return to Step 1.
