With the ignition on, turn the cruise control off and hold the set switch in untill the check engine light starts to flash. cout the flashes. it will flash a two digit number. eg 5 flashs, a short pause and 5 more flashes would be code 55. it may fash several several codes.
If it flashed code 55 there is no faults.

My question is in relation to the first one I guess.. My father is a truck driver and hes out on the road right now but he keeps getting this diagnostic code error. The errors are 55 and 93. He has a 2007 Kenworth truck with a CAT engine. Any help would be greatly appreciated if anyone knows what they translate to.
Thank you -
If the CAT owners manual is still in the truck they're listed in there.

does any body know what 5 volt below normal code 232.4 mean

many sensors have 3 wires, Signal Ground, Signal Return and 5V Signal Supply, some have 2 and some have more than 3 but the problem is likely on the 3 wire sensors
This code is looking at the 5v signal from the ECM and it has found the voltage is lower than 5v, this can be an ECM problem or excessive load on the 5v Ref or a short to ground in the sensors 5v supply signal internal circuit.
You will need Diagnostic Software, unplug each sensor, one at a time until the 5v supply returns to normal, then replace that sensor if the plug looks OK, if it never comes back to normal, start tracing the 5v signal wire from the ECM to each sensor and look for a rubbed throuh wire... You will nees a schematic and Pinout diagram.Last edited: Sep 3, 2010

I have a CAT 3406E showing a fault code 1-11 which is showing as "cylinder 1 fault" on the posted PDF file for codes. Does anyone know what the sensors interpret? i.e. Injector, compressor, valves?????? -

I have a 2006 Freightliner Classic with a cat C15. It just started this.
Oil pressure went up to 71lbs and engine temperature went down to 140. No codes and just been serviced. Any ideas why.
