Trouble Code Descriptions

NOTE:
CODE 2, 4, 11, or exceeds 13: count the number of blinks again, if the indicator is in fact, blinking these codes, substitute a known-good ECU and re-check. If the indication goes away, replace the original ECU.

The PGM-FI dash warning light and ECU LED may come on, indicating a system problem, when, in fact, there is a poor or intermittent electrical connection. First, check the electrical connections, clean or repair connections if necessary.
