Q: Is the diagnostic trouble code set?

YES : Perform the relevant troubleshooting.
NO :  Go to Step 3.

STEP 3. Check whether the diagnostic trouble code is 
reset.
Q: Is diagnostic trouble code No.C1631 set?

YES : Replace the AWC-ECU. (Refer to 

P.23C-295

). Then 

go to Step 4.

NO :  Intermittent malfunction. (Refer to GROUP 00 

− How 

to Cope with Intermittent Malfunction 

P.00-15

).

STEP 4. Check whether the diagnostic trouble code is 
reset.
Q: Is diagnostic trouble code No.C1631 set?

YES : Return to Step 1.
NO :  This diagnosis is complete.

Code No. C1632: Engine CAN Data (not received)

CAUTION

• If there is any problem in the CAN bus lines, 

an incorrect diagnostic trouble code may be 
set. Prior to this diagnosis, diagnose the CAN 
bus lines.

• Whenever the ECU is replaced, ensure that 

the CAN bus lines are normal.

.

OPERATION

AWC-ECU communicates with the engine control 
module via the CAN bus lines.

.

DIAGNOSTIC TROUBLE CODE SET 
CONDITIONS

This diagnostic trouble code is set when the CAN 
signal of the engine control module cannot be 
received.

.

PROBABLE CAUSES

• Malfunction of the CAN bus line

• Damaged connectors (Engine control module)

• Malfunction of engine control module

• Malfunction of AWC-ECU

DIAGNOSTIC PROCEDURE

STEP 1. M.U.T.-III CAN bus diagnostics.
Use scan tool to perform the CAN bus diagnosis.
Q: Is the check result normal?

YES : Go to Step 2.
NO :  Repair the CAN bus lines. (Refer to GROUP 54C 

− 

Troubleshooting 

P.54C-17

). After repairing the CAN 

bus line, go to Step 2.

CAUTION

• If there is any problem in the CAN bus lines, 

an incorrect diagnostic trouble code may be 
set. Prior to this diagnosis, diagnose the CAN 
bus lines.

• Whenever the ECU is replaced, ensure that 

the CAN bus lines are normal.

.

OPERATION

AWC-ECU communicates with A/T-ECU via the CAN 
bus lines.

.

• Malfunction of the CAN bus line

• Damaged connectors (A/T-ECU)

• Malfunction of A/T-ECU

• Malfunction of AWC-ECU

• Coding failure (installation of M/T for a vehicle 

with A/T specification, failure coding of A/T for a 
vehicle with M/T specification)

DIAGNOSTIC PROCEDURE

STEP 1. M.U.T.-III CAN bus diagnostics.
