NOTE:
1. Problem verification:
Is DTC 2618 indicated?
YES
The failure is duplicated, go to step 2.
NO
Intermittent failure, the system is OK at this time.
2. Determine possible failure area (LaneWatch camera power and ground, others):
LaneWatch camera 6P connector
Is there about 6 - 9 V?
YES
Go to step 7.
NO
Go to step 3.
3. Determine possible failure area (BSM CAM VCC line, SH BSM CAM line):
Measure the voltage between test points 1 and 2.
Is there about 6 - 9 V?
YES
Go to step 6.
NO
Go to step 4.
4. Open wire check (BSM CAM VCC line):
Measure the voltage between test points 1 and 2.
Is there about 6 - 9 V?
YES
There is an open in the wire between the audio unit and the LaneWatch camera. Replace the affected shielded harness.
NO
The BSM CAM VCC wire is not open. Go to step 5.
5. Shorted wire check (BSM CAM VCC line):
Audio unit connector C (24P)
Is there continuity?
YES
There is a short to body ground in the wire between the audio unit and the LaneWatch camera. Replace the affected shielded harness.
NO
Replace the audio unit - Refer to: Audio Unit Removal and Installation (Display Audio Type (7-inch Screen), or Audio Unit Removal and Installation (Color Audio Type (5-inch Screen).
6. Open wire check (SH BSM CAM line):
Audio unit connector C (24P)
Is there continuity?
YES
Replace the audio unit - Refer to: Audio Unit Removal and Installation (Display Audio Type (7-inch Screen), or Audio Unit Removal and Installation (Color Audio Type (5-inch Screen).
NO
There is an open in the wire between the audio unit and the LaneWatch camera. Replace the affected shielded harness.
7. Shorted wire check (UNIT TO LWC, LWC TO UNIT lines):
Audio unit connector C (24P)
Is there continuity?
YES
There is a short to body ground in the wire(s) between the audio unit and the LaneWatch camera. Replace the affected shielded harness.
NO
The UNIT TO LWC wire and the LWC TO UNIT wire are not shorted. Go to step 8.
8. Shorted wire check (UNIT TO LWC line to LWC TO UNIT line):
Is there continuity?
YES
There is a short in the wires between the audio unit and the LaneWatch camera. Replace the affected shielded harness.
NO
The UNIT TO LWC to the LWC TO UNIT wire are not shorted. Go to step 9.
9. Open wire check (UNIT TO LWC, LWC TO UNIT lines):
Check for continuity between test points 1 and 2.
Is there continuity?
YES
Replace the LaneWatch camera.
NO
There is an open in the wire(s) between the audio unit and the LaneWatch camera. Replace the affected shielded harness.
