Service

^ Test the battery using the Midtronics MRC340V. If the battery needs charging, use Midtronics InCharge 940 (INC-940) tester/charger. Ensure that proper Midtronics test code is included with warranty claim.

Tip:

Use the generate test code and print function of MRC340V and/or INC 940 to obtain appropriate Midtronics test code which is required for warranty claims. If battery requires replacing, see Repair Manual Group 27 Starter current supply, in ElsaWeb. Failure to provide the proper Midtronics test code may result in a denied claim.

When encountering this concern it is necessary to reset the door control modules. This is performed by disconnecting the battery for a period of no less than 1 hour. Once the reset door control modules procedure is performed, it is necessary to perform a restoring electrical power procedure, and clear DTCs, see Repair Manual Group 27, Battery Reconnecting in ElsaWeb.

Tip:

Remember to reset basic settings of motors in order to reactivate the auto up or down.
