How to Troubleshoot Circuits at the BCM Module and MCM Connectors
Special Tools Required
^ Digital multimeter KS-AHM-32-003 (1) or a commercially available digital multimeter
^ Backprobe set 07SAZ-001000A (2)
If DTC troubleshooting requires voltage or resistance checks at the BCM module and MCM connectors, remove the BCM module and MCM connectors and test it.
1. Remove the IPU lid.
2. Connect the backprobe adapters (A) to the stacking patch cords (B), and connect the cords to a digital multimeter.
3. Using the wire insulation as a guide for the contoured tip of the backprobe adapter, gently slide the tip into the connector from the wire side until it touches the end of the wire terminal.
