19. CHECK SYMPTOM
1. Fill in described symptoms on the column “Symptom” in the check sheet.
2. Connect all connectors, and then make sure that the symptom is reproduced.
OK or NG
OK >> GO TO 20.
NG >> Refer to LAN-18, "
Example of Filling in Check Sheet When Initial Conditions Are Not Reproduced"
.
20. CHECK UNIT REPRODUCIBILITY
Performs the following procedure for each unit, 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.
–A/T assembly
–AFS control unit
–BCM
–Low tire pressure warning control unit
–Steering angle sensor
–Intelligent Key unit
–Unified meter and A/C amp.
–NAVI control unit
–RAS control unit
–Driver seat control unit
–ABS actuator and electric unit (control unit)
–ECM
–IPDM E/R
Check results
Reproduce>>Install removed unit, and then check the other unit.
Not reproduced>>Replace removed unit.
IPDM E/R Ignition Relay Circuit InspectionNKS0042H
Check the following. If no malfunction is found, replace the IPDM E/R.
