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
–LDW camera unit
–Low tire pressure warning control unit
–Steering angle sensor
–Intelligent Key unit
–Unified meter and A/C amp.
–NAVI control unit
–Pre-crash seat belt control unit
–Driver seat control unit
–ABS actuator and electric unit (control unit)
–ICC sensor integrated 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 InspectionNKS00415
Check the following. If no malfunction is found, replace the IPDM E/R.
IPDM E/R power supply circuit. Refer to PG-30, "Check IPDM E/R Power Supply and Ground Circuit" .
Ignition power supply circuit. Refer to PG-12, "IGNITION POWER SUPPLY — IGNITION SW. IN “ON”
AND/OR “START”" .
