Without OBD II
On G20 models, the ECU is located behind the center console. On J30, M30 and Q45 models, the ECU is located behind the RH kick panel.
If a malfunction occurs within the ECU/fuel injection system, a diagnostic trouble code may be stored in the ECU and the ‘‘Check Engine’’ lamp will blink. There is also a lamp built into the ECU which will concurrently blink. To read Code output, proceed as follows:
1. Turn ignition On, but do not start engine.
2. Using a small screwdriver, turn diagnostic mode selector switch, located on side of ECU, fully clockwise.
3. Wait two seconds, then rotate switch to full counterclockwise position.
4. A malfunction code can be read as the long (0.6 second) blink, indicating the first digit of a two digit number and the short (0.3 second) blink, indicating the second digit.
Ensure that the diagnostic switch is to the full counterclockwise position whenever the vehicle is in use.
w/OBD II
On G20 and I30 models, connect a suitable Scan Tool to the DLC, located under instrument panel fuse box cover.
On J30, Q45 and QX4 models, connect a suitable Scan Tool to the DLC, located under or on lower portion of instrument panel.
Clearing Codes
If using a scan tool, follow tool manufacturer’s instructions to clear Codes.
A second, though more time consuming method of clearing Codes involves using a small screwdriver to turn the diagnostic mode selector switch, located on the side of the ECM/ECU, fully clockwise. After waiting two seconds, rotate the switch to the full counterclockwise position. The diagnosis will end and memory will then be cleared.
