Diagnosing HIM Error Codes
If the red No.3 LED on the HIM came on or was flashing during the update, do this:
1. Leave the ignition switch in ON (II) while you disconnect the HIM from the vehicle's DLC.
2. If not already done, load the latest HDS software onto the iN workstation.
3. Connect the HIM to the iN workstation. Connect the small end of the PC interface cable to the PC port on the HIM.
4. If not already done, connect the PC end of the blue PC interface cable to the 9P serial port on the iN workstation.
5. Connect the 110 VAC/12 VDC power supply to the HIM and to a wall outlet.
6. Restart the CM Update application on the iN workstation.
7. On the right side of the screen, click on the view error button.
8. Click on View Error at the bottom of the screen to display the problem encountered while the HIM was connected to the vehicle.
^ If you get a Code 40 error message (usually caused by a communication error between the HIM and the workstation), do this:
- Do the HIM self-test procedure (see HIM Self- Test).
- Move the blue PC interface cable to another communication port on the back of the computer.
- If one of the communication ports on the back of the computer has another cable connected to it, disconnect that cable, leave it disconnected
during the HIM procedure, and connect the blue PC interface cable to that port.
- Connect the HIM to another computer. (Some iN workstations require an internal communication port setup procedure. For help, call the iN
Support Center at 800-245-4343.)
If you get a Code 50 error message (usually caused by a communications error between the HIM and the vehicle's DLC), do this:
- Diagnose and clear any DTCs. (The control unit/module must be free of DTCs before you can update it.)
- Make sure there's a good connection between the HIM and the DLC.
- Retry the update using the procedures in this service bulletin or on the back of the HIM.
- If needed, call Tech Line for further help.
