MIL Light (MIL)
MIL light will illuminate when ignition switch is turned to ON position (engine not running). This is a bulb check. When engine is started, MIL light should turn OFF. If light remains ON, on-board diagnostics has detected an engine or transmission system fault. A/T self-diagnosis is performed by A/T Control Unit (ATCU) in combination with ECM. Self-diagnosis codes indicated by MIL are stored in both ATCU and ECM memory. Codes may be retrieved from vehicles equipped with a MIL light by using the following procedure:
1.Ensure ignition is in ON position and engine is off (KOEO). Turn diagnostic test mode selector, (located on side of ECM), fully clockwise. Wait 2 seconds, and turn diagnostic test mode selector fully counterclockwise. This puts ECM into Diagnostic Test Mode II (code retrieval mode).
2.DTCs are indicated by the MIL light "blinking" sequence. A sequence of LONG (MIL light ON for .6 second) blinks indicates the first and second digits of the DTC.
3.The third and fourth digits are indicated by a sequence of SHORT (MIL light ON for .3 second) blinks. Example: MIL blinks 10 times for 6 seconds (.6 x 10 times), and then blinks 3 times for about 1 second (.3 x 3 times). This indicates MIL DTC 1003.
4.ECM will not switch to Diagnostic Test Mode II when engine is running. When engine is turned off after code retrieval, power to ECM is lost after 5 seconds. Turn ECM switch to full counterclockwise position. This returns system to Diagnostic Test Mode I which provides bulb test and system monitoring functions.
