(2)

Turn the ignition switch from "LOCK" (OFF) position to "ON"
position.

(3)

Check if DTC is set.

(4)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Is the DTC set?

YES:

 Replace the ETACS-ECU.

DTC U0100: Engine control module CAN timeout

M15410600051USA0000010000

｠

If DTC U0100 is set to the ETACS-ECU, always
diagnose the CAN bus line.

｠

Before  replacing  the  ECU,  ensure  that  the
communication circuit is normal.

TROUBLE JUDGMENT
If  the  signal  from  engine  control  module  cannot  be
received, the ETACS-ECU sets DTC U0100.

JUDGMENT CRITERIA
After the following statuses continue to be true for 5
seconds, if the communication with the engine control
module cannot be established for 0.6 second or more,

the  ETACS-ECU  determines  that  a  problem  has
occurred.

｠

No abnormality is present to the network.

｠

Ignition switch is in the ON position.

｠

No abnormality is present to the power supply fuse,
or the odometer value is at 80.5 km (50.0 miles) or
more.

｠

ETACS-ECU system voltage is at 10-16 volts.

TROUBLESHOOTING HINTS

｠

The Engine control module may be defective.

｠

The ETACS-ECU may be defective.

｠

The CAN bus may be defective.

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. Refer to "How to connect the
Scan Tool (M.U.T.-III) P.54Ad-5."

(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 54D,

Diagnosis P.54D-17).

STEP 2. Using scan tool MB991958, read the engine control
module diagnostic trouble code.
Check if DTC is set to the engine control module.

Q:Is the DTC set?

YES:

 Troubleshoot the engine. (Refer to GROUP 13Ab,

Diagnostic Trouble Code Chart P.13Ab-44.)

NO:

 Go to Step 3.

STEP 3. Using scan tool MB991958, read the transaxle
control module diagnostic trouble code.
Check if DTC U0100 is set to the transaxle control module.

Q:Is the DTC set?

YES:

 Go to Step 4.

NO:

 Go to Step 5.

STEP 4. Recheck for diagnostic trouble code.
Check again if the DTC is set to the ETACS-ECU.

(1)

Erase the DTC.

(2)

Turn the ignition switch from "LOCK" (OFF) position to "ON"
position.

(3)

Check if DTC is set.

(4)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Is the DTC set?

YES:

 Replace the engine control module.

NO:

 The trouble can be an intermittent malfunction such

as a poor connection or open circuit in the CAN bus lines
between the engine control module and the ETACS-ECU.
(Refer to GROUP 00, How to Cope with Intermittent
Malfunction P.00-15)
