General Information - Diagnostic Trouble Code (DTC) Index DTC: Occupant Classification System (OCS)
Description and Operation
Occupant Classification System (OCS)
CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle
NOTES:
It is advisable not to use a cellular phone or to have a cellular phone in close proximity when working on the restraints
control module or associated systems
Given the legal implications of a restraints system failure, harness repairs to Air Bag module circuits are not acceptable.
Where the text refers to "REPAIR the circuit", this will normally mean the replacement of a harness.
If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
Warranty Policy and Procedures manual, or determine if any prior approval programme is in operation, prior to the installation
of a new module/component.
Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to
the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the
manufacturer-approved diagnostic system)
Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests
Inspect connectors for signs of water ingress, and pins for damage and/or corrosion
If diagnostic trouble codes are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent
concern may be the cause. Always check for loose connections and corroded terminals
Where an 'on demand self-test' is referred to, this can be accessed via the 'diagnostic trouble code monitor' tab on the
manufacturers approved diagnostic system
Check DDW for open campaigns. Refer to the corresponding bulletins and SSMs which may be valid for the specific
customer complaint and carry out the recommendations as required.
The table below lists all diagnostic trouble codes (DTCs) that could be logged in the occupant classification system, for
additional diagnosis and testing information refer to the relevant diagnosis and testing section.
For additional information, refer to: Air Bag and Safety Belt Pretensioner Supplemental Restraint System (SRS) (501-20
