CCS - cruise control switch
TCS - transmission control switch... also known as OCS - overdrive cancel switch MLP - manual lever position sensor TSS - turbine shaft speed sensor OSS - output shaft speed sensor EPC - electronic pressure control solenoid (inside trans) HFCM - horizontal fuel conditioning module - oops, sorry... that's for diesels BPP - brake pedal position sensor.... used to be called BOO - brake on/off switch CHT - cylinder head temperature sensor EOT - engine oil temperature MPLearn - misfire profile learn SAW - spark angle word signal IVD - interactive vehicle dynamics CMDTC - continuous memory diagnostic trouble code - a problem that the PCM has seen but may not be present now ODDTC - on demand code - a problem that is present at the time of the test CMP - camshaft position sensor CKP - crankshaft position sensor BPS - brake pressure sensor PPS - power steering pressure switch VCT - variable cam timing solenoid FPM - fuel pump module FPS - fuel pressure sensor VSM - vehicle security module LCM - lighting control module DSM - drivers seat module Actually, there seems to be new ones born every day...... toss in the special requirements for diesel and turbocarged applications, it can be hard to keep up. |

Man... I wish I was allowed to do a cut and paste from the factory DVD
manuals..... you could get the full benefit of EGRMDSD and 4WDSWRTN..... "John" > wrote in message om... > MIL - malfunction indicator light (or lamp) > |
