DIAGNOSIS
COMMENTS ON TROUBLE SYMPTOM
Input signal from the keyless entry transmitter is used to operate
the keyless entry system. If the signal is abnormal, the keyless
entry system will not work normally.
PROBABLE CAUSES
⦆
Battery discharged in the transmitter
⦆
Malfunction of the transmitter
⦆
Malfunction of WCM
DIAGNOSTIC PROCEDURE
Required Special Tools:
⦆
MB992006: Extra fine probe
⦆
MB991223: Harness set
⦆
MB991958: Scan Tool (M.U.T.-III Sub Assembly)
⦆
MB991824: Vehicle Communication Interface (V.C.I.)
⦆
MB991827: M.U.T.-III USB Cable
⦆

WIRELESS CONTROL MODULE (WCM)
42C-81
DIAGNOSIS
STEP 2. Check the transmitter battery.
AC004486
Measure the voltage of the transmitter battery.
⦆
The value should be approximately 2.5 - 3.2 volts.
Q:Is the measured voltage approximately 2.5 - 3.2 volts?
YES:
Go to Step 3.
NO:
Replace the battery. If the transmitter can be
registered normally, and operates normally, it indicates
that the transmitter is sending normal signal to the WCM.
STEP 3. Register the keyless entry secret code using a
known-normal transmitter of the same type again, and
check the trouble symptom.
(1)
Register a known-good transmitter of the same type.
(2)
Check if the signals from the transmitter switches are
received.
Q:Can the transmitter be registered correctly?
YES:
Replace the original transmitter with a new one.
NO:
Replace the WCM.(Including when the new transmitter
cannot be registered). Replace WCM and register the ID
codes (Refer to P.42C-85). If the transmitter works
normally, the input signal from the transmitter should be
normal.
