Diagnosis & Testing: Notes

NOTE: The DME system tests are limited. Complete testing of the DME system requires an oscilloscope, voltmeter, ohmmeter and special test leads to insert in multiple pin CU connector. On 944-S a self-diagnosis with fault memory is integrated into the DME control unit. Faults can be called from memory with a special diagnostic Tester (9268), which can be connected to diagnostic connector on DME control unit wiring harness.
