Evaluating Display Group 01




Display group 01 (compressor cut-off conditions)


NOTE:
- When display field 1 shows compressor cut-off condition codes 1, 8, 11 or 12, the A/C Clutch -N25- cannot be actuated during Output DTM. If compressor cut-off condition code 5 appears in addition to other compressor cut-off conditions, ignore code 5. Output Diagnostic Test Mode (DTM) (Function 03)
- If several compressor cut-off condition codes appear simultaneously in display field 1, conditions are displayed alternately or the cut-off condition assigned the highest priority by A/C control head -E87- is displayed.
- With A/C pressure switch -F129- open, compressor cut-off condition "1" appears next (excess refrigerant system pressure) and the compressor is shut off. If A/C pressure switch -F129- remains open for more than 30 seconds, it switches over to compressor cut-off condition "3" (empty refrigerant system, vacuum).
