TROUBLE DIAGNOSIS
Revision: 2006 July 2007 FX35/FX45
Note 1: Confirm tire pressure is normal.
Note 2: ON/OFF timing of ABS warning lamp
ON: Approx. Within 2 seconds after ignition switch is turned ON, or when a malfunction is detected.
OFF: Approx. 2 seconds after ignition switch is turned ON (when system is in normal operation) and VDC/TCS function is not activa ted.
Note 3: ON/OFF timing of VDC OFF indicator lamp
ON: Approx. Within 2 seconds after ignition switch is turned ON, or when a malfunction is detected and VDC OFF switch is ON.
OFF: Approx. 2 seconds after ignition switch is turned ON (when system is in normal operation.) And when VDC OFF switch is OFF.
Note 4: ON/OFF timing of SLIP indicator lamp
ON: Approx. Within 2 seconds after ignition switch is turned ON, or when a malfunction is detected and VDC/TCS function is activa ted
while driving.
OFF: Approx. 2 seconds after ignition switch is turned ON (when system is in normal operation) and VDC/TCS function is not activa ted.
Flashing: VDC/TCS function is active during driving
Note 5: Only AWD models.
Note 6: Serves as EBD warning lamp.

CONSULT-II CHECKING SYSTEMPFP:00000
DescriptionNAS0006J

CONSULT-II is a hand-held type tester. When it is connected with a diagnostic connector equipped on the
vehicle side, it will communicate with the control unit equipped in the vehicle and then enable various
kinds of diagnostic tests.

Refer to “CONSULT-II Software Operation Manual” for more information.
