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

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
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
NO : Replace the combination meter (Refer to GROUP
54A, Combination meter assembly
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.
