- NO RESP/NOT EQUIP for DDM, GO to PINPOINT TEST C .
- NO RESP/NOT EQUIP for DATC module, see CLIMATE CONTROL SYSTEM - GENERAL INFORMATION .
- SYSTEM PASSED, retrieve and record the continuous diagnostic trouble codes (DTCs), clear the continuous DTCs and carry out self-test diagnostics for the FEM, REM, DDM, and DATC module.
