Normal Mode Code Retrieval

  1. Connect scan tool to Data Link Connector No. 3 (DLC3). See Figure. Turn ignition on. Turn on scan tool. Retrieve any trouble codes stored in memory following scan tool instructions. See the TROUBLE CODE IDENTIFICATION  table.
  2. Codes recorded may not have illuminated MIL. When certain malfunctions or trouble codes initially occur, they will be temporarily stored in ECM memory, but MIL will not illuminate.
  3. The second time malfunction or trouble code is detected, MIL will illuminate, provided ignition is turned off and then back on after malfunction or trouble code was first detected. This process is referred to as Two Trip Detection Logic and only applies to most trouble codes.
  4. Also record freeze-frame data. If using Toyota scan tool, ensure tool is in normal mode. CHECK MODE will erase all codes.
NOTE: When scan tester is switched from normal mode to check mode, all trouble codes and freeze-frame data will be erased. DO NOT switch modes until all trouble codes and freeze-frame data are recorded.
