PINPOINT TEST G542831p36 : AIR CLEANER SOLENOID VALVE DRIVE CIRCUIT MALFUNCTION

PINPOINT TEST G542831p36 : AIR CLEANER SOLENOID VALVE DRIVE CIRCUIT MALFUNCTION

G542831t133 : CHECK THE POWER SUPPLY TO THE AIR CLEANER SOLENOID VALVE
1. Key off.
2. Disconnect the air cleaner solenoid valve electrical connector, FH10.
3. Key on, engine off.
4. Make sure the EMS relay is engergized.
5. Measure the voltage between:

Air cleaner solenoid valve Battery
connector FH10, harness side
Pin 01 Negative terminal

- Is the voltage greater than 10 volts?

-> YES
GO to Pinpoint Test G542831t134.

-> NO
REPAIR the circuit between the air cleaner solenoid valve and battery. This circuit includes splice FHS04, FHS60, fuse 37 of the front power distribution box and the EMS relay. CLEAR the DTC. TEST the system for normal operation.

G542831t134 : CHECK THE AIR CLEANER SOLENOID VALVE TO ECM CIRCUIT FOR HIGH RESISTANCE
1. Key off.
2. Disconnect the ECM electrical connector, PI300.
3. Measure the resistance between:

Air cleaner solenoid valve ECM connector PI300,
connector FH10, harness side harness side
Pin 02 Pin 49

- Is the resistance greater than 5 ohms?

-> YES
REPAIR the high resistance circuit. CLEAR the DTC. TEST the system for normal operation.

-> NO
GO to Pinpoint Test G542831t135.

G542831t135 : CHECK THE AIR CLEANER SOLENOID VALVE TO ECM CIRCUIT FOR SHORT CIRCUIT TO POWER
1. Key on, engine off.
2. Measure the voltage between:

Air cleaner solenoid valve Battery
connector FH10, harness side
Pin 02 Negative terminal

- Is the voltage greater than 3 volts?

-> YES
REPAIR the short circuit. CLEAR the DTC. TEST the system for normal operation.

-> NO
GO to Pinpoint Test G542831t136.

G542831t136 : CHECK THE AIR CLEANER SOLENOID VALVE TO ECM CIRCUIT FOR SHORT CIRCUIT TO GROUND
1. Measure the resistance between:

Air cleaner solenoid valve Battery
connector FH10, harness side
Pin 02 Negative terminal

- Is the resistance less than 10,000 ohms?

-> YES
REPAIR the short circuit. CLEAR the DTC. TEST the system for normal operation.

-> NO
INSTALL a new air cleaner solenoid valve. CLEAR the DTC. TEST the system for normal operation.
