Using the Check Engine/Malfunction Indicator Light

To Display Diagnostic Trouble Codes





1. Turn the ignition switch ON (Do not start)
2. Ground the L-wire (No. 10 pin) in the data link connector for 2.5 seconds.

Example: 1 2 2 3:





3. The first output is the fault code stored or the code "no fault detected" (4444).
4. Each blink code in repeated infinitely till the next step is ordered.
5. Repeated until the next step is entered by grounding the L-wire for 2.5 second. After that, the next code follows.
6. The last output consists out of the code for "end of output" (3333). After stepping further as described above, the diagnostic test mode is left.

Actuator Control Sequence Procedure








1. The L-wire (No.10 pin) in the data link connector has to be grounded before ignition ON. (Do not start).
2. Ignition switch ON (Do not start). Then the actuator control is interrupted immediately. If time for grounding of L-wire is too long, the cycle starts from the beginning.
3. Repeated until the next step is entered by another grounding the L-wire. After that, the next code and the next actuator follows.
4. The last output consists out of the code for "end of output". After stepping further as described above, the diagnosis mode is left.
