General information

Accessing
Ensure ignition switched OFF.
Remove ignition key.
Connect analogue voltmeter between data link connector
(DLC) terminals as follows:
Connect voltmeter negative (-) terminal to DLC terminal El m.

used.
Insert ignition key.
Count voltmeter needle deflections. Note trouble codes.
Compare with trouble code table.
If no trouble codes are output: Check fuses.
Each trouble code consists of two groups of one or more
needle deflections m.
A 1,5 second pause separates each trouble code group [C].
Voltmeter needle deflection duration: 0,5 second [A].
A 0,5 second pause separates each deflection [Bl.
A 2,5 second pause separates each trouble code [Dl.
For example: Three 0,5 second flashes - 1,5 second
pause - two 0,5 second flashes. Trouble code 32
displayed - ignition key - no communication.
A 4,5 second pause follows the last trouble code, before
they are repeated.
