WIRELESS CONTROL MODULE (WCM)
42C-20
DIAGNOSTIC TROUBLE CODE PROCEDURES
DTC B1731: Engine control module communication timeout
CAUTION
• When the DTC B1731 is set, be sure to diag-
nose the CAN bus line.
• When replacing the ECU, always check that
the communication circuit is normal.
.
DTC SET CONDITION
WCM checks that the engine control module data
has been received via the CAN bus lines, and if not,
sets the DTC No. B1731.
.
TECHNICAL DESCRIPTION (COMMENT)
If no data [ETACS transmits engine random number
data to WCM via the CAN bus lines] is received from
the engine control module via the CAN bus lines
when the ignition switch is turned to ON position, it is
judged as abnormal.
.
TROUBLESHOOTING HINTS
• Malfunction of CAN bus line
• Malfunction of WCM
• Malfunction of engine control module
• Malfunction of ETACS-ECU

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 (Vehicles with
CAN communication system)
STEP 1. Using scan tool MB991958, diagnose the CAN bus
line.
CAUTION
To prevent damage to scan tool (MB991958), always turn
the ignition switch to the "LOCK" (OFF) position before
connecting 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) Diagnose the CAN bus line.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the CAN bus line found to be normal?
YES : Go to Step 2.
NO : Repair the CAN bus line. (Refer to GROUP 54C,
). On completion, go to Step 2.
STEP 2. Using scan tool MB991958, read the engine
control module diagnostic trouble code.
Check again if the DTC is set to the engine control module.
Q: Is the DTC set?
YES : Troubleshoot the MFI system (Refer to GROUP 13A,
Diagnostic trouble code chart
<2.4L
Engine> or GROUP 13B, Diagnostic trouble code
chart
<3.0L Engine>).
NO : Go to Step 3.
STEP 3. Using scan tool MB991958, read the other system
diagnostic trouble code.
Check if DTC U0100 is set to ETACS-ECU.
Q: Is the DTC set?
YES : Go to Step 5.
NO : Go to Step 4.

STEP 4. Recheck for diagnostic trouble code.
Check again if the DTC is set to the WCM.
(1) Turn the ignition switch from "LOCK" (OFF) position to "ON"
position.
(2) Check if DTC is set.
(3) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the DTC set?
YES : Replace WCM and register the ID codes. (Refer to
.) After registering the ID codes, go to Step
6.
NO : The trouble can be an intermittent malfunction (Refer
to GROUP 00
− How to use
Troubleshooting/inspection Service Points
− How to
Cope with Intermittent Malfunction
STEP 5. Recheck for diagnostic trouble code.
Check again if the DTC is set to the WCM.
(1) Turn the ignition switch from "LOCK" (OFF) position to "ON"
position.
(2) Check if DTC is set.
(3) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the DTC set?
YES : Replace the engine control module and record the
VIN (Refer to GROUP 00 - How To Perform Vehicle
Identification Number (VIN) Writing
). Then go
to Step 6.
NO : The procedure is complete.
STEP 6. Recheck for diagnostic trouble code.
Check again if the DTC is set to the WCM.
(1) Turn the ignition switch from "LOCK" (OFF) position to "ON"
position.
(2) Check if DTC is set.
(3) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the DTC set?
YES : Replace the ETACS-ECU.
NO : The procedure is complete.
DTC B1761: VIN code not programmed
CAUTION
• When the DTC No. B1761 is set, be sure to
diagnose the CAN bus line.
• When replacing the ECU, always check that
the communication circuit is normal.
.
DTC SET CONDITION
WCM sets DTC B1761 when no VIN is recorded in it.
.
TECHNICAL DESCRIPTION (COMMENT)
WCM determines that the abnormality is present
when no VIN is recorded in it.
.
TROUBLESHOOTING HINTS
• VIN not programmed
• Malfunction of the WCM
