Hi I have an astra H fitted with temic control unit,
The passenger passenger airbag has gone off,
i have replaced airbag and am using opcom to look at module and clear data
i cannot clear the error and airbag light remains on with the faults stored
The unit is MRSZ Temic-
Part Number 13288176 software A3300RG3 v3.4.0 alpha code cc ( read via opcom)
I have 5 errors
B1000-56 - CONTROL UNIT NOT RE-USABLE
B0051-00 - AIRBAG DEPLOYED
B0055-00 SIDE AIRBAG ACTIVATED
B0021-04 PASSENGER SIDE AIRBAG SQUIB CIRCUIT OPEN CIRCUIT
B0021-0E PASSENGER SIDE AIRBAG SQUIB CIRCUIT LOW RESISTANCE
When i read the measuring blocks in opcom
i get the following readings
driver airbag stage 1 squib cct resistance - 2.8 ohm
Passngr airbag stage 1 squib cct resistance - 2.2 ohm
driver airbag stage 2 squib cct resistance - 7.3 ohm
passngr airbag stage 2 squib cct resistance - 7.3 ohm
driver side airbag squib circuit resistance - 2.3 ohm
passenger side airbag squib circuit resistance - 2.3 ohm
driver curtain airbag squib resistance - 7.3 ohm
passenger curtain airbag squib resistance - 7.3 ohm
Driver pretensioner squib resistance - 2.1 ohm
passenger pretensioner squib resistance - 2.5 ohm
I have tried clearing data and errors within opcom
I used the activation screen and activated the faults above
and followed the sequence provided at http://opcomforum.yolasite.com/resou...ent%20Data.pdf
am i missing something ?
can this be cleared - is the temic unit locked ?
Just out of interest,
I have seen similar threads on here where people use dumps and re-write back to eeprom,
How do I do a dump of the module and how do i re-load it with corrected file.
Thanks
