Seat Belt Pretensioner Diagnostics

WARNING: To avoid the possibility of personal injury caused by accidental deployment of the pretensioner, disconnect the vehicle battery and wait at least 10 minutes for all voltages to fully discharge before working on the pretensioner system. This covers the possibility of the normal capacitor discharge circuits being inoperative and failing to discharge the capacitor when instructed to do so.

WARNING: Do not make any electrical measurements on the pretensioner squib. Electrical measurement devices can induce sufficient voltage to cause unintentional firing of the pretensioner assembly

050A Pretensioner Squib Leak to Battery Positive

050A will be logged if the resistance of the pretensioner squib feed or return line to a positive potential falls below 1kΩ.

Procedure

1. Read the warnings given at the start of this pretensioner diagnostics section.
2. Connect the PDU to the lower diagnostic socket and access the pretensioner control module. Verify that an 050A code is logged and note if the fault is shown as intermittent. Note any other codes in the DTC log and then clear all codes.
3. Switch off the ignition and wait at least 10 minutes for the pretensioner squib firing capacitors to fully discharge before continuing with this procedure.
4. Disconnect the pretensioner squib connector at the rearward harness. Disconnect the pretensioner control module and temporarily cheat the squib shorting link.

Note: The control module harness connector has a shorting link which short circuits the squib lines together when the connector is displaced. Carefully insert a suitable non-metallic cheater to remove the short circuit between pins 11 and 12 before continuing with fault diagnosis.
