98 C5 PCM ECM- ADVICE identifying DIODE(w Label gone) on PCM circuit board to buy NEW
Hi to everyone. This is my first ever Vette forum post. I’d appreciate ADVICE on HOW to IDENTIFY the DIODE of my PCM / ECM found to have one of its legs corroded when I removed the circuit board from the housing. (See File attachment for Pics) My Vette is a 1998 Base Coupe w 5.7 Ltr. A friend who has repaired ECM’s feels strongly that replacing this diode should restore the PCM to functioning properly. The problem is when he cleaned the corrosion off the diode, the numbers labeled on the component were gone. Money is tight right now, so MY GOAL is to IDENTIFY the DIODE so that I can buy a NEW replacement and have my friend perform the repair -- solder it onto the board in place of the old one. ------- I’m thinking that the easiest, and PROBABLY IDEAL SCENARIO is if someone has the same PCM and can take a picture of their CLEARLY LABELED same diode on their circuit board à I’d be really grateful if they would then post it in a reply to this post, or Email it to me. OR ---- if someone has another viable solution, I’m definitely open to suggestions !! FYI – 2 GM dealers have told me that the correct PCM Part # is 19332289 which is ALSO found in a 98 Camaro and a 98 Firebird ---- additionally, 16238212 is stated to also be a valid GM part # per Car-Part.com, as well as Flagship One (a worldwide supplier of refurbished modules).
I appreciate any help or input ! Thanks a lot ! TJ
