STEP 2. Using scan tool MB991958, check for any 
diagnostic trouble code. 
Check if DTC is set to the KOS-ECU <vehicles with KOS> or 
WCM <vehicles with WCM>.
(1) Turn the ignition switch to the "ON" position.
(2) Check whether the KOS or WCM related DTC is set.
(3) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the DTC set?

YES <vehicles with KOS>  : Troubleshoot the KOS (Refer 

to GROUP 42B, KOS 

P.42B-35

YES <vehicles with WCM>  : Troubleshoot the WCM 

(Refer to GROUP 42C, WCM 

P.42C-18

).

NO  :  Go to Step 3.

STEP 3. Check the keyless operation key <KOS> or 
keyless entry transmitter <WCM>.
Q: is the keyless operation key <KOS> or keyless entry 

transmitter <WCM> normally?
YES : Go to Step 4.
NO <vehicles with KOS>  : Troubleshoot the KOS (Refer 

to GROUP 42B, KOS 

P.42B-35

).

NO <vehicles with WCM>  : Troubleshoot the WCM (Refer 

to GROUP 42C, WCM 

P.42C-18

).

STEP 4. Using scan tool MB991958, check data list. 
Use the ETACS-ECU data list to check the signals related to 
the theft-alarm function.

• Turn the ignition switch to the "ACC" position.

• Turn the ignition switch to the "LOCK" (OFF) position (with 

ignition key <vehicles with WCM> or emergency key <vehi-
cles with KOS> inserted).

• Open each door.

• Open the liftgate.

• Open the hood.

• Close each door.

• Close the liftgate.

• Open the hood.

STEP 6. Check the theft-alarm indicator.
Q: Is the theft-alarm indicator in good condition?

YES : Go to Step 7.
NO :  Replace the center panel unit.

STEP 7. Check ETACS-ECU connector C-307 for loose, 
corroded or damaged terminals, or terminals pushed back 
in the connector.
Q: Is the ETACS-ECU connector C-307 in good condition?

YES : Go to Step 8.
NO :  Repair the damaged parts.

STEP 8. Measure the voltage at ETACS-ECU connector 
C-307.
(1) Disconnect ETACS-ECU connector C-307, and measure 

the voltage wiring harness side.

(2) Measure the voltage between ETACS-ECU connector-307 

(terminal No. 2) and the body ground.

• The voltage should measure approximately 12 volts 

(battery positive voltage).

Q: Is the measured voltage approximately 12 volts (battery 

positive voltage)?
YES : Go to Step 10.
NO :  Go to Step 9.

STEP 9. Check the Wiring harness between ETACS-ECU 
connector C-307 (terminal No. 2) and fusible link (36).

• Check the power supply line for open circuit and short cir-

cuit.

Q: Is the check result normal?

YES : The trouble can be an intermittent malfunction (Refer 

to GROUP 00, How to use 
Troubleshooting/inspection Service Points 

− How to 

Cope with Intermittent Malfunction
