  1. With key inserted in ignition switch, cycle ignition switch to ON position 3 times. On third cycle, leave ignition switch in ON position. Record 2-digit trouble codes as displayed by flashing MIL.
  2. For example, Code 34 is displayed as a series of 3 flashes in rapid succession, followed by a 4-second pause, then 4 flashes in rapid succession. After a slightly longer pause, other stored codes are displayed in numerical order.
  3. When MIL begins to flash trouble codes, it cannot be stopped. Start over if necessary. Code 55 indicates end of trouble code display.
    NOTE: If trouble code exists that is not related to cruise control system, see SELF-DIAGNOSTICS SYSTEM in the TESTS W/CODES - 3.3L article in the ENGINE PERFORMANCE Section.
  4. Refer to TROUBLE CODES  table to translate trouble code number to a circuit description (same description is displayed in DRB display). Once trouble area is identified, refer to TEST TC-1A  under SELF-DIAGNOSTIC TESTS to diagnose problem.
