Cat trouble codes

Yes,they are slightly lower at 14.7:1 for a C15 marine.

Do you think I should look at lower compression pistons if I'm going to keep pushing high boost??????

**CaterpillarWrench** · 02.05.2009

Definitely would'nt hurt.But I'm not sure where you're gonna find pistons.

I was told this by someone that I don't trust a lot "take the pistons out and take 20 thou off the top that will lower the compression enough"

UNDERPSI, may or may not help. had similar problems once with MXS acert. Cat told me driver ID codes were different than those read thru data port. cant understand why Cat would do that....

UNDERPSI, You mentioned your driver read 5 and 5 using the cruise control switiches. In Cat's manuals code 55 = No deteced Faults.

179-02, 175-05, 135-12, 032-000, 192-00

I got him to try the thing with his cruise switch and hes getting 5 and 5 flashes

On my truck if you turn the key off and back on it will not read the code with the cruize switch. it will only give 55 that is no stored codes. when the ck engine lt come on read the codes before you turn the key off.

Thanks I'll let the driver know that

Sound like it may be some sort of ECM or display fault, the three digit number tells you the component or system (called Component identifier or CID), and the two digit number tells you whats wrong with the component (called Failure mode identifier or FMI) but all of those you have listed do not make sense for your engine... eg. 175-05 would be engine oil temp open circuit as 175 is engine oil temp sensor and -05 is open circuit or current low. the others are hard to figure out but I dont think they belong with a truck engine.
135 is left steering manifold, the others are not listed by cat at all.
-00 is data valid but above normal limit
-02 data incorrect or intermittent
-05 current low (open circuit)
-12 bad device or component, bad signal

I am driving a 2000 Western Star with a 3406e, can you tell me how to activate the trouble codes with the cruise switch?
