STEP 5. Combination meter connector, intermediate
connector, and parking brake switch connector check:
C-03, C-22, D-125
Check the contact status of the terminals.
Q: Is the check result normal?

YES : Go to Step 6.
NO : Repair the defective connector. Then go to Step 8.

STEP 6. Check the wiring harness between C-03
combination meter connector terminal No.4 and D-125
parking brake switch connector terminal No.1.
Check the power supply line for short circuit.
Q: Is the check result normal?

YES : Replace the combination meter. (Refer to GROUP

54A

− Combination Meter

P.54A-118

). Then go to

Step 7.

NO : Repair the wiring harness. Then go to Step 7.

STEP 7. Check whether the diagnostic trouble code is
reset.
Q: Is diagnostic trouble code No.C1614 set?

YES : Replace the AWC-ECU. (Refer to

P.23C-295

). Then

go to Step 8.

NO : Intermittent malfunction. (Refer to GROUP 00

− How

to Cope with Intermittent Malfunction

P.00-15

STEP 8. Check whether the diagnostic trouble code is
reset.
Q: Is diagnostic trouble code No.C1614 set?

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

Code No.C1616: Cranking Signal System (stuck ON)

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 receives the signal of the ignition switch
from ETACS-ECU via CAN communication.

DIAGNOSTIC TROUBLE CODE SET
CONDITIONS

This diagnostic trouble code is set when the cranking
signal is continued for the specified time during driv-
ing.

PROBABLE CAUSES

• Malfunction of the ETACS-ECU

• Ignition switch malfunction

• Damaged harness wires and connectors

• 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 3.
NO : Repair the CAN bus lines. (Refer to GROUP 54C

−

Troubleshooting

P.54C-17

). After repairing the CAN

bus line, go to Step 2.

STEP 2. Check whether the diagnostic trouble code is
reset.
Q: Is diagnostic trouble code No.C1616 set?

YES : Go to Step 3.
NO : This diagnosis is complete.

STEP 3. M.U.T.-III diagnostic trouble code.

• Check the KOS diagnostic trouble code. (Refer to GROUP

42B

− Troubleshooting

P.42B-35

• Check the WCM diagnostic trouble code. (Refer to GROUP

42C

− Troubleshooting

P.42C-18

• Check the ETACS diagnostic trouble code. (Refer to

GROUP 54A

− Troubleshooting

P.54A-732

Q: Is the diagnostic trouble code set?

YES : Perform the relevant troubleshooting.
NO : Go to Step 4.

STEP 4. M.U.T.-III data list.
Item 30: Ignition SW (CAN input) (Refer to data list reference
table

P.23C-254

Q: Is the check result normal?

YES : Go to Step 9.
NO : Go to Step 5.

STEP 5. Ignition switch check
(1) Disconnect C-210 ignition switch connector, and check the

continuity between the terminals No.1 and No.5 at the
ignition switch side.

(2) Turn the ignition switch to the "ON" position.

OK: No continuity

Q: Is the check result normal?

YES : Go to Step 6.
NO : Replace the ignition switch. (Refer to GROUP 54A

−

). Then go to Step 10.

STEP 6. Ignition switch connector, ETACS-ECU connector
check: C-210, C-315
Q: Is the check result normal?

YES : Go to Step 7.
NO : Repair the defective connector. Then go to Step 10.
