4. CHECK FRONT FOG LAMP INPUT SIGNAL
With CONSULT-II
1. Turn ignition switch OFF.
2. Disconnect front fog lamp RH and LH connectors.
3. Select “IPDM E/R” on CONSULT-II, and select “ACTIVE TEST” on “SELECT DIAG MODE” screen.
4. Select “LAMPS” on “SELECT TEST ITEM” screen.
5. Touch “FOG” screen.
6. When front fog lamp is operating, check voltage between front fog lamp RH and LH harness connectors and ground.
Without CONSULT-II
1. Turn ignition switch OFF.
2. Disconnect front fog lamp RH and LH connectors.
3. Start auto active test. Refer to PG-21, "
Auto Active Test" .
4. When front fog lamp is operating, check voltage between front fog lamp RH and LH harness connectors and ground.
OK or NG
OK >> GO TO 6.
NG >> GO TO 5.
5. CHECK FRONT FOG LAMP CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect IPDM E/R connector.
3. Check continuity between IPDM E/R harness connector (A) and front fog lamp (RH and LH) harness connector (B).
OK or NG
OK >> Replace IPDM E/R. Refer to PG-28, "Removal and
Installation of IPDM E/R" .
NG >> Repair harness or connector.
