DIAGNOSIS
Diagnosis and troubleshooting of the MRS III system is fault driven and can be accessed
using the DIS Tester or MoDiC. The control module performs a self test of the system every
time the ignition is switched on ( this includes the satellite sensors and seat occupancy sen-
sor). Any faults with the system will cause the warning lamp in the instrument cluster to
remain illuminated after the engine is started.
Installation of a new or replacement control module requires ZCS coding also using the DIS
or MoDiC.
When servicing or replacing any MRS III components, always follow precautionary mea-
sures outlined in the repair manual of TIS. this includes disconnecting the battery prior to
any repair or maintenance work being performed.
All airbag components are part number specific by model and require verification in the
EPC to ensure the correct component is being installed.
