Circuit/System Verification
| 1. |
Verify DTC B356A is not
set. |
| 2. |
Verify DTC B0987 is not
set. |
| ⇒ |
If DTC is set, refer to Circuit/System
Testing. |
Circuit/System Testing
| 1. |
Ignition OFF, disconnect the
harness connector at the K74 Vehicle Direction Camera Control
Module and the harness connector at the S48D Multi-Function Switch
2 - Instrument Panel. |
| 2. |
Ignition ON, test for greater
than 11 V between the ignition circuit terminal 3 at the S48D
Multi-Function Switch 2 - Instrument Panel harness connector and
ground. |
| ⇒ |
If less than the specified value, test the
ignition circuit for a short to ground or an open/high
resistance. |
| 3. |
Test for less than 0.3 V
between the control circuit terminal 8 at the S48D Multi-Function
Switch 2 - Instrument Panel harness connector and ground.
|
| ⇒ |
If greater than the specified value, test the
control circuit for a short to voltage. |
| 4. |
Ignition OFF, test for
infinite resistance between the control circuit terminal 8 at the
S48D Multi-Function Switch 2 - Instrument Panel harness connector
and ground. |
| ⇒ |
If less than the specified value, test control
circuit for a short to ground. |
| 5. |
Test for less than 5 Ω
between the S48D Multi-Function Switch 2 - Instrument Panel control
circuit terminal 8 and the control circuit terminal 4 at the K74
Vehicle Direction Camera Control Module harness connector
|
| ⇒ |
If greater than the specified value, test the
control circuit for an open/high resistance. |
| 6. |
If all circuits test normal,
connect the harness connector to the K74 Vehicle Direction Camera
Control Module, replace the S48D Multi-Function Switch 2 -
Instrument Panel and verify the DTC does not reset. |
| ⇒ |
If the DTC resets, replace the K74 Vehicle
Direction Camera Control Module. |
Repair Instructions
Perform the
Diagnostic Repair Verification after completing the diagnostic
procedure.
