Code No. C1616: Cranking Signal System (Stuck ON)
 
 
caution
  • If there is any problem in the CAN bus lines, an incorrect diagnosis 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.
 
 
DIAGNOSIS CODE SET CONDITIONS
This diagnosis code is set when the cranking signal is continued for the specified time during driving.
 
 
PROBABLE CAUSES
  • Malfunction of the ETACS-ECU
  • Malfunction of the ignition switch
  • Damaged harness wires and connectors
  • Malfunction of AWC-ECU
 
 
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-IIISE CAN bus diagnostics.
Use M.U.T.-IIISE to perform the CAN bus diagnosis.
Is the check result normal?
Go to Step 2.
Repair the CAN bus lines (Refer to GROUP 54C - Troubleshooting ).
 
STEP 2. M.U.T.-IIISE other system diagnosis code.
  • Check the KOS diagnosis code (Refer to GROUP 42B - Troubleshooting ) <Vehicles with KOS>.
  • Check the ETACS diagnosis code (Refer to GROUP 54A - Troubleshooting ).
Is the diagnosis code set?
Perform the relevant troubleshooting.
Go to Step 3.
 
STEP 3. M.U.T.-IIISE data list.
Check the following data list (Refer to ).
  • Item No.47: Ignition status
Is the check result normal?
Go to Step 7.
Go to Step 4.
 
STEP 4. Ignition switch check
(1) Disconnect ignition switch connector, and check the continuity between the power supply and start signal at the ignition switch side.
(2) Turn the ignition switch to the "ON" position.
OK: No continuity
Is the check result normal?
Go to Step 5.
Replace the ignition switch (Refer to GROUP 54A - Ignition Switch ).
 
STEP 5. Check of short circuit in start signal line between ignition switch connector and ETACS-ECU connector.
Is the check result normal?
Go to Step 6.
Repair the defective connector or the wiring harness.
 
STEP 6. M.U.T.-IIISE other system data list.
Check the data list of the ETACS (Refer to GROUP 54A - ETACS ).
  • Item No.110: Starter switch
Is the check result normal?
Go to Step 7.
Replace the ETACS-ECU (Refer to GROUP 54A - ETACS-ECU ).
 
STEP 7. Check whether the diagnosis code is set again.
Is diagnosis code No.C1616 set?
Replace the AWC-ECU (Refer to ).
Intermittent malfunction (Refer to GROUP 00 - How to Cope with Intermittent Malfunction ).
