Dodge Ram Pickup/Chassis Cab/Truck D/W 5.9L Turbo Diesel (1992 – 1995) OBD1 Codes

Model	Year	Engine identification	System
Ram Pickup/Chassis Cab D/W 5.9L Turbo Diesel	1992-93	ETA	SBEC II
Ram Truck 5.9L Turbo Diesel	1994-95	ETB	SBEC II

General information

Malfunction indicator lamp (MIL) will illuminate if certain faults are recorded.
Trouble codes can be displayed by the MIL or by using a Scan Tool connected to the data link connector (DLC).

Accessing

Within 3 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] [D].
A long pause separates each trouble code [1] [E].
For example: Trouble code 44 displayed [1]
End of test sequence indicated by trouble code 55.
Trouble codes can also be displayed by using a Scan Tool connected to the data link connector (DLC):

o Ram Pickup [2]
o Ram Truck [3]

Erasing

Ensure ignition switched OFF.
Disconnect battery ground cable for at least 30 seconds.
Reconnect battery ground cable.
Repeat accessing procedure to ensure no trouble codes remain in ECM fault memory.

NOTE: Disconnecting battery ground lead may also erase memory from electronic units, such as radio.

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