Neon 2.0L	1996-97	ECB/ECC	SBEC III

General information

Malfunction indicator lamp (MIL) will illuminate or flash if certain faults are recorded.
ECM operates in backup mode if sensors fail, to enable vehicle to be driven to repair shop.
Trouble codes can be displayed by the MIL or by using a Scan Tool connected to the data link connector (DLC).

Accessing

Flash codes

Within 5 seconds switch the ignition key ON-OFF-ON-OFF-ON .
Count MIL flashes. Note trouble codes.
Each trouble code consists of two groups [1] [A].
The first group of flashes indicate the ‘tens’ of the trouble code.
The second group of flashes indicate the ‘units’ of the trouble code.
A short pause separates ‘tens’ and ‘units’ [1] [B].
A long pause separates each trouble code [1] [C].
For example: Trouble code 21 displayed [1].
End of test sequence indicated by trouble code 55.

P codes & Hex codes

Trouble codes can be displayed by using a Scan Tool connected to the data link connector (DLC):
Breeze [2]
Neon [3]

Erasing

• Trouble codes can only be erased by using a Scan Tool connected to the data link connector (DLC).
