Troubleshooting Circuits At the BCM Module and MCM Connectors
Troubleshooting Circuits at the MCMSpecial 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 MCM connectors, remove the MCM and test it.
1. Remove the IPU lid.
2. Remove the harness holder (A), the MCM relay (B), and the clip (C).
3. Remove the bolts (D), disconnect ground bolt (E), and then raise the MCM (F).
4. Connect the backprobe adapters (A) to the stacking patch cords (B), and connect the cords to a digital multimeter.
5. 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.
