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 veh icle to be driven to repair shop.
- 1995 Summit -Federal: Trouble codes can be displayed by the MIL or by using a Scan Tool connected to the data link connector(s) (DLC ).
Accessing
Summit -1995 Federal
Flash codes
- Ensure ignition switched OFF.
- Access 16 pin data link connector (DLC) [1]
- Jump data link connector (DLC) terminal 1 and ground [2]
- Switch ignition ON .
- Count MIL flashes. Note trouble codes. Compare with trouble code table.
- Each trouble code consists of two groups [3] :
o Long flashes indicate the ‘tens’ of the trouble code [3] A.o Short flashes indicate the ‘units’ of the trouble code [3] D.o A short pause separates each trouble code group [3] C.o A long pause separates each trouble code [3] E .o For example: Trouble code 22 displayed [3]
- If MIL remains ON : Suspect faulty engine control module (ECM).
- If constant short flashes are displayed, no trouble code is stored.
P codes
• Trouble codes can also be displayed by using a Scan Tool connected to the data link connector(s) (DLC).Summit -except 1995 Federal
• Trouble codes can only be displayed by using a Scan Tool connected to the 12 pin or 16 pin data link connectors (DLC) [1].Summit Wagon/Talon
• Trouble codes can only be displayed by using a Scan Tool connected to the data link connector (DLC):- Summit Wagon [4]
- Talon [5]
Erasing
NOTE: Disconnecting battery ground lead may cause driveability problems until the engine management system relearns basic values.- Ensure ignition switched OFF.
- ~isconnect battery ground cable for at least 15 seconds.
- Reconnect battery ground lead.
- Repeat checking procedure to ensure no data remains in ECM fault memory.
- Trouble codes can also be erased by using a Scan Tool connected to the data link connector(s) (DLC).
