6. UNIT REPRODUCIBILITY INSPECTION
Perform the following procedure for each unit on the CAN network, and then perform reproducibility test.
1. Turn ignition switch OFF.
2. Disconnect the battery cable from the negative terminal.
3. Disconnect the unit connector.
4. Connect the battery cable to the negative terminal.
5. Make sure that the symptom filled in the “Symptom” of the check sheet is reproduced. (Do not confuse it
with the symptom related to removed unit.)
6. Make sure that the same symptom is reproduced.
Inspection results
Reproduced>>Install removed unit, and then check the other unit.
Not reproduced>>Replace removed unit.
IPDM E/R Ignition Relay Circuit InspectionUKS004TW
