THERMO KING TRUCK, TRAILER, CR, DAS, AND DSR ALARM CODES THIS DOCUMENT SHOWS ALL CURRENT TRUCK, TRAILER, CR, DAS, AND DSR ALARM CODES. NOT ALL CODES ARE POSSIBLE ON ALL UNITS. IF THE ALARM APPLIES TO A MULTI-TEMP ZONE, THAT ZONE WILL BE IDENTIFIED. BE SURE TO RECORD ALL ALARMS THAT OCCUR. THEY ARE VALUABLE TO THE SERVICE TECHNICIAN. ALARM CODE NUMBERS MARKED WITH PARTENTHESIS (XX) MAY EXIST WITH ALARM CODE 84 AND MAY CLEAR AUTOMATICALLY. COLOR CODE DEFINITIONS OK TO RUN CHECK AS SPECIFIED TAKE IMMEDIATE ACTION THESE ARE SUGGESTIONS ONLY. ALWAYS CONSULT YOUR COMPANY FOR FINAL DECISIONS.
