54 -CHASSIS ELECTRICAL > 54A-CHASSIS ELECTRICAL > ETACS > DIAGNOSIS CODE PROCEDURES > CODE No. B1762 IGNITION OFF CURRENT DRAW (IOD) FUSE DISCONNECTED
Code No. B1762 IOD fuse not seated fully
 
 
caution
  • Before replacing the ECU, ensure that the power supply circuit, the earth circuit and the communication circuit are normal.
 
 
TROUBLE JUDGEMENT
  • When voltage at the power supply fuse (No.22) drops below 5 V with the ignition switch "ON" and then the ACC OFF signal is detected for 5 seconds, the ETACS-ECU will store diagnosis code No. B1762.
 
 
PROBABLE CAUSES
  • Malfunction of fuse No.22
  • Malfunction of the ETACS-ECU
  • Malfunction of the KOS&OSS-ECU <Vehicles with KOS>
  • Damaged harness wires and connectors
 
 
DIAGNOSIS PROCEDURE
STEP 1. Check the power supply fuses (No.22)
 
Check the power supply fuses (No.22) (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - Inspection Service Points for a Blown Fuse ).
Is the fuse in good condition?
Go to Step 2.
Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - Inspection Service Points for a Blown Fuse . Then go to Step 5.
 
STEP 2. Check of short to power supply, short to earth, and open circuit in IODI line between fusible link and ETACS-ECU connector
Is the check result normal?
YES <Vehicles with KOS> : Go to Step 3.
YES <Vehicles without KOS> : Go to Step 4.
NO : Repair the connector(s) or wiring harness. Then go to Step 5.
 
STEP 3. Check the M.U.T.-IIISE Diagnosis code for other systems
Check that the KOS&OSS-ECU set a diagnosis code.
Is the diagnosis code set?
Diagnose the KOS&OSS-ECU. Refer to GROUP 42B, Troubleshooting .
Go to Step 4.
 
STEP 4. Check of short to power supply, short to earth, and open circuit in ACC line between ignition switch (ACC) <Vehicles without KOS> or KOS&OSS-ECU (ACC) <Vehicles with KOS> and ETACS-ECU connector
Is the check result normal?
Go to Step 5.
Repair the connector(s) or wiring harness. Then go to Step 5.
 
STEP 5. Check whether the diagnosis code is set again.
Check again if the diagnosis code is set in the ETACS-ECU.
(1) Erase the diagnosis code.
(2) Turn the ignition switch from "LOCK" (OFF) position to "ON" position.
(3) Check if diagnosis code is set.
Is the diagnosis code set?
Replace the ETACS-ECU.
If the trouble symptom is resolved, an intermittent malfunction such as poorly engaged connector(s) or wiring harness is suspected (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction ).
