Summary of change:
Subpage of MembersPage/BmwMFiftyTwo '''Grounding''' M52 Gnds: MOT88/ 4, 7, 28, 32, 34, 38, 39, 40, 41, 42, 43, 56, 58, 63, 67, 70, 71, 72 * please check by measurement (harness and ecu pins) Pin63 is optional. Some gnd pins in harness have no connectivity, are only connected by ecu pin * ECU passed all functional tests (including main relay and fuelpump p259 outputs) ** needless to say, grounds were connected during HW-tests (eg. the signalgenerator is grounded to the other grounds of test-bench) Check just in case: * '''BMW88/43 must be grounded (connected to BMW88/34 in ECU) if it is not grounded in harness and DVM diode measurement shows more than 0mV between these 2 ECU pins also''' ** otherwise the harness is not compliant with the GenBoard/Manual/GroundConnections and p259 might be damaged ** EC36/26 GND connected to GND5 inside all BMW M52 ECU (double-test this)
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
