Unsuccessful Programming Recovery
NOTE:
- Ensure the EL-52100 (MDI 2) is used when programming the vehicle. Using the EL-47955 (MDI) will result in a programming failure.
- It may be necessary to use another EL-52100 (MDI 2) and / or cables to verify proper operation to eliminate the possibility of faulty equipment.
- If Ethernet programming fails, ensure there is no fault in the Ethernet circuits between the X84 Data Link Connector and K56 Serial Data Gateway Module. Refer to Scan Tool Does Not Communicate with Vehicle to diagnose these Ethernet circuits.
In the event of an interrupted or unsuccessful programming event, perform the following steps:
- Exit Service Programming Systems and disconnect all programming equipment from the vehicle.
- Disconnect all battery voltage or ignition voltage sources from the control module. All voltage sources must be removed for a minimum of 10 min. This can be done several ways and should be completed by using the least intrusive way. This can vary depending on vehicle and control module location and can be done by one of the options listed below:
- Removing all fuses supplying battery voltage and ignition voltage to the control module.
- Disconnecting all harness connectors from the control module.
- Check the 12 V battery voltage with a digital multimeter before disconnecting any battery cables leads. If the voltage is 13.5 V or above, the Battery Maintenance Mode is active. The technician must wait for the T18 Battery Charger to deactivate before disconnecting the battery negative cable. For more information, refer to Charging System Description and Operation . With Battery Maintenance Mode inactive, perform a 12 V battery disconnect by disconnecting the battery negative cable. Refer to Battery Negative Cable Disconnection and Connection .
WARNING:Always ensure the Battery Maintenance Mode is inactive before disconnecting the low voltage 12 volt battery (or batteries). This mode can be active with the ignition off, regardless of whether the vehicle charging cord is plugged in or not. When this mode is active, the on-board high voltage battery charger (s) will energize the 12 volt battery cables and charge the 12 volt battery (or batteries). Disconnecting any battery cables while this mode is active may result in an electrical shock or a burn from hot battery cable leads.
- Reconnect all Battery voltage and Ignition voltage sources to the Control Module.
- Close down the current session of Techline Connect and reopen a new session.
- Verify the control module, data link connector, and programming tool connections are secure and the tool software is up to date.
- Ignition / Vehicle OFF, ensure that the key fob is inside the vehicle and not moved for the duration of the programming to prevent an inadvertent power mode change during programming.
- Access the Service Programming System (SPS) and follow the on-screen instructions for the K219 Lighting Control Module.
- Verify the control module can be programmed.
- If the control module can not be programmed
- Ignition ON / Vehicle in Service Mode for 1 min.
- Ignition / Vehicle OFF.
- Access SPS and follow the on-screen instructions for the K219 Lighting Control Module.
- For facilities using an internet firewall, ensure firewall settings are not blocking file downloads and / or require elevated rights.
- For United States and Canada GM dealers, the appropriate firewall settings can be found in the GM DEALER INFRASTRUCTURE & SECURITY GUIDELINES (DISG) section 2.d.vii.
- Verify the control module can be programmed.
- If the control module can not be programmed, replace the K219 Lighting Control Module.
- Go to next step: If the control module can be programmed
- Clear DTCs.
NOTE:If programming is still not successful after the second programming attempt, check the following:
- Go to next step: If the control module can be programmed
- Clear DTCs.
