ON-VEHICLE INSPECTION

PROCEDURE

1. INSPECT TAILLIGHT RELAY (TAIL)

(a) Remove the taillight relay from the main body ECU (driver side junction block assembly).

(b) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
3 - 5	Battery voltage applied to terminals 1 and 2	Below 1 Ω
3 - 5	Battery voltage not applied between terminals	10 kΩ or higher
3 - 4	Battery voltage applied to terminals 1 and 2	10 kΩ or higher
3 - 4	Battery voltage not applied between terminals	Below 1 Ω

If the result is not as specified, replace the taillight relay.

2. INSPECT FOG LIGHT RELAY (FOG)

(a) Remove the fog light relay from the main body ECU (driver side junction block assembly).

(b) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
3 - 5	Battery voltage applied to terminals 1 and 2	Below 1 Ω
3 - 5	Battery voltage not applied between terminals	10 kΩ or higher

If the result is not as specified, replace the fog light relay.

3. INSPECT BI-XENON RELAY

(a) Remove the BI-XENON relay from the power distributor (engine room junction block assembly).

(b) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
3 - 5	Battery voltage applied to terminals 1 and 2	Below 1 Ω
3 - 5	Battery voltage not applied between terminals	10 kΩ or higher

If the result is not as specified, replace the BI-XENON relay.

Mass or Volume Air Flow Circuit Low Input (P0102,P0103)
DESCRIPTION The mass air flow meter is a sensor that measures the amount of air flowing through the throttle valve. The ECM uses this information to determine the fuel injection time and to provide the appropriate air-fuel ratio. Inside the mass air flow ...

ECU Power Source Circuit
DESCRIPTION When the ignition switch is turned to ON, voltage from the ECM's MREL terminal is applied to the EFI MAIN relay. This causes the contacts of the EFI MAIN relay to close, which supplies power to terminal +B of the TCM. WIRING DIAGRAM PR ...
