ABS + DSC + Brake Light Trifecta RESOLVED

[thesalboy]

2003 4.4i DSC 5.7

Lights came on sporadically at first, but then all the time.

Codes always included pressure sensor errors, but all over the place and never the same code after each reset:

51 Pressure sensor, line
72 Pressure sensor, zero deviation
73 Pressure sensor, line
81 Pressure sensor line interruption
114 Pressure sensor (offset)
115 pressure sensor scatter

Also got: 105 [69) Brake light switch plausibility [new switch made no difference]

And: 80 Brakes were overheated [HA!]

Never had a wheel speed sensor code.

I sent the DSC module to Cheap ABS. Their tip of removing the headlight to get to the module worked great - I had to zip tie some hoses out of the way and get creative with extensions and adapters that were skinny and long enough but not too long to get to the torx screws. Car was stored outside in the meantime so I covered the ABS unit and plug with plastic wrap and aluminum foil to keep water out.

All good since January (4 months).
