⇒ | If the parameter does not cycle between the specified values, replace the DDS. |
⇒ | If the test lamp is always ON, test both control circuits for a short to voltage. If the circuit tests normal, replace the appropriate door switch. |
⇒ | If the test lamp is always OFF, test both control circuits for a short to ground or an open/high resistance. If the circuit tests normal, replace the door switch. |
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
