Simulation function
- The simulation function can drive the output parts set in each module regardless of the control condition.
- The simulation function can be used by the M-MDS. (See SIMULATION INSPECTION ).
How to make use of PID/data monitor function and simulation function (Ex. Wipers do not operate correctly)
- A system (such as input/output side) where a malfunction is occurring can be specified by using the PID/data monitor function or simulation function.
Input system examination (windshield wiper switch to body control module (BCM))
- Operate the windshield wiper switch and verify that the windshield wiper operation condition is in conjunction with the body control module (BCM) PID "F_WIP" (windshield wiper operation condition table) value.
- Not applicable
| Windshield wiper switch condition | PID/data monitor item "F_WIP" value | Diagnostic result | Malfunctioning system | Inspection item |
|---|---|---|---|---|
| OFF | OFF | Normal | - | - |
| LO | OFF | Malfunction | Input system (Windshield wiper switch-Body control module (BCM)) |
|
| HI | FrontWiper On Hi | Normal | - | - |
| INT/AUTO | FrontWiperINT Auto On | Normal | - | - |
Output system examination (body control module (BCM) to wiper motor)
- Verify that the wipers are operating correctly using the body control module (BCM) simulation PID item "F_WIP_REQ" (windshield wiper drive) and "R_WIP_REQ" (rear wiper drive).
- Not applicable
| Simulation item "F_WIP_REQ" value | Simulation item "R_WIP_REQ" value | Windshield wiper operation condition | Rear wiper operation condition | Diagnostic result | Malfunctioning system | Inspection item |
|---|---|---|---|---|---|---|
