Inspection Procedure 4: The interior lamp automatic shutoff function does not work normally.
 
 
caution
  • Before replacing the ECU, ensure that the power supply circuit, the earth circuit and the communication circuit are normal.
 
 
 
 
COMMENTS ON TROUBLE SYMPTOM
The ETACS-ECU operates the interior lamp automatic shutoff function in accordance with the input signals below.
  • Ignition switch (ACC)
  • Ignition switch (IG1)
  • Door switches
If this function does not work normally, these input signal circuit(s) or the ETACS-ECU may have a problem. Also, "Interior lamp auto cut timer" may be set to "Disable" through customisation.
 
 
PROBABLE CAUSES
  • Malfunction of door switch
  • Malfunction of the room lamp
  • Malfunction of the ETACS-ECU
  • Damaged harness wires and connectors
 
 
DIAGNOSIS PROCEDURE
STEP 1. Customise function check
Use the ETACS-ECU customise function to check to see which of the followings other than "Disable" the "Interior lamp auto cut timer" is set.
  • 3 minutes
  • 30 minutes
  • 60 minutes
Is the check result normal?
Go to Step 2.
Use the ETACS-ECU customise function to set the "Interior lamp auto cut timer" to other than "Disable" (Refer to ).
 
STEP 2. M.U.T.-IIISE diagnosis code
Check if diagnosis code is set in the ETACS-ECU.
Is the diagnosis code set?
Troubleshoot the ETACS-ECU (Refer to ).
Go to Step 3.
 
STEP 3. M.U.T.-IIISE data list
Use the ETACS-ECU service data to check the signals related to the interior lamp automatic shutoff function.
  • Turn the ignition switch to the "LOCK" (OFF) position.
  • Open each door.

Normal conditions are displayed for all the items. : Go to Step 4.
Normal condition is not displayed for item No. 79. : Troubleshoot the ETACS-ECU. Refer to Inspection Procedure 2 "The ignition switch (IG1) signal is not received" .
Normal condition is not displayed for item No. 111. : Troubleshoot the ETACS-ECU. Refer to Inspection Procedure 1 "The ignition switch (ACC) signal is not received" .
Normal condition is not displayed for item No. 81. : Troubleshoot the ETACS-ECU. Refer to Inspection Procedure 5 "The front door switch (driver’s side) signal is not received" .
Normal condition is not displayed for item No. 82. : Troubleshoot the ETACS-ECU. Refer to Inspection Procedure 6 "The front door switch (passenger’s side) signal is not received" .
Normal condition is not displayed for item No. 83. : Troubleshoot the ETACS-ECU. Refer to Inspection Procedure 7 "The rear door switch (RH) signal is not received" .
Normal condition is not displayed for item No. 84. : Troubleshoot the ETACS-ECU. Refer to Inspection Procedure 8 "The rear door switch (LH) signal is not received" .
 
STEP 4. Retest the system
Check that the interior lamp automatic shutoff function works normally.
Is the check result normal?
The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to use Troubleshooting/inspection Service Points - How to Cope with Intermittent Malfunction ).
Replace the ETACS-ECU.
