DTC List - Engine Control System

Fig. 81 Fault Code Index:

Trouble Codes
If output indicates CODE 11 or exceeds 17, count the number of blinks again. If the indicator is in fact, blinking these codes, substitute a known-good ECU and recheck. If the indication goes away, replace the original ECU.
The Check Engine 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.
