The control box also gives access to a diagnostic mode that can be entered to retrieve stored error codes and service intervals. Warning and Information Messages During operation the following messages may display to inform the operator of system status. Diagnostic Mode - Accessing Error Codes To access the diagnostic mode and retrieve stored error codes, perform the following steps: • Turn the vehicle ignition “ON” but do not start the engine • Press and hold the “OFF“ button (Figure 1) on the Control Box until “DIAGNOSTICS” is displayed. • Press “OFF” button to scroll down. Press the “ON” button to scroll up. • To exit diagnostic mode, press both the “OFF” and “ON” buttons simultaneously.Technical Support Subject DTM Error Codes Version Document Department Revision Details Revised by Tech Engineering Implemented A EXT-DTM-002 Tech Document Release BDJ 10Sept2018 DB 10Sept2018 N/A 10Sept2018 Knowledge Base: www.kb.vmacair.com Page 2 of 3 Email: tech@vmacair.com Web: www.vmacair.com Technical Support: 1(888)241-2289 Toll Free:1(800)738-8622 Fax: 1(877)740-3201 Figure 1 A maximum of 10 error codes will be saved. After 10 errors have occurred, any additional error code will bump the oldest code from the system, allowing only the most recent codes to be available for retrieval. When troubleshooting, keep a record of each trouble code that displays, in the order of occurrence, for reference. Error codes display in the following format (Figure 2). Figure 2 TROUBLE SHOOTING There are 7 possible error codes in the DTM system. Error Code Display Fault Possible Problem(s) 01 OVER TEMP Compressor is too hot • Low compressor oil level. • Faulty or crushed cooler hoses. • Exceeded cooling capacity of the compressor cooling system • OEM changes in cooling. • Non-standard application. 02 TEMP PROBESHORT Compressor temperature probe wires shorted or failed. • Faulty temperature probe • Crushed temperature probe wires. • Pinched or bare wires that are • grounded 03 TEMP PROBE OPEN Compressor temperature probe disconnected or failed • Disconnected temperature probe • Faulty temperature probe • Broken temperature probe wiresTechnical Support Subject DTM Error Codes Version Document Department Revision Details Revised by Tech Engineering Implemented A EXT-DTM-002 Tech Document Release BDJ 10Sept2018 DB 10Sept2018 N/A 10Sept2018 Knowledge Base: www.kb.vmacair.com Page 3 of 3 Email: tech@vmacair.com Web: www.vmacair.com Technical Support: 1(888)241-2289 Toll Free:1(800)738-8622 Fax: 1(877)740-3201 Error Code Display Fault Possible Problem(s) 04 BATTERY LOW.
