Diagnosis Procedure

IONIZER


Diagnosis Procedure

1.CHECK POWER SUPPLY FOR IONIZER
1. Turn ignition switch OFF.
2. Disconnect ionizer connector.
3. Turn ignition switch ON.
4. Press fan (UP: +) switch.
5. Check voltage between ionizer harness connector and ground.





Is the inspection result normal?
YES - GO TO 2.
NO - Check 10A fuse (No. 3, located in the fuse block). Refer to Fuse Block - Junction Box (J/B).
- If fuse is OK, check harness for open circuit. Repair or replace if necessary.
- If fuse is NG, replace fuse and check for short circuit. Repair or replace if necessary.
2.CHECK ION ON/OFF SIGNAL
Check voltage between ionizer harness connector and ground.





Is the inspection result normal?
YES - GO TO 3.
NO - GO TO 4.
3.CHECK ION CONTROL MODE OUTPUT SIGNAL
Check voltage between ionizer harness connector and ground.





Is the inspection result normal?
YES - GO TO 5.
NO - GO TO 6.
4.CHECK CIRCUIT CONTINUITY BETWEEN UNIFIED METER AND A/C AMP. AND IONIZER
1. Turn ignition switch OFF.
2. Disconnect unified meter and A/C amp. connector.
3. Check continuity between unified meter and A/C amp. harness connector and ionizer harness connector.





Is the inspection result normal?
YES - Replace unified meter and A/C amp.
NO - Repair harnesses or connectors.
