Test Procedure

-- Perform a preliminary check to verify the customers complaint. Refer to PRELIMINARY CHECK .

Checking voltage

-- Remove the Secondary Air Injection (SAI) Pump Relay -J299-.

-- Using a multimeter, check the Secondary Air Injection (SAI) Pump Relay -J299- socket 1 (relay terminal 30) to Ground.

Specified value: Battery voltage.

If the specified value was Not obtained:

-- Check the wiring connection from the Secondary Air Injection (SAI) Pump Relay -J299- socket 1 (relay terminal 30) to the Battery positive cable for an open circuit or high resistance. Refer to Wiring Diagrams for pin locations.

-- Check the wiring connections for damage, corrosion, loose or broken terminals.

-- If necessary, repair the faulty wiring connection.

If the specified value was obtained:

-- Using a multimeter, check the resistance of the Secondary Air Injection (SAI) Pump Relay -J299- socket 2 (relay terminal 87) to Secondary Air Injection (SAI) Pump Motor -V101- harness connector, terminal 2.

Specified value: 1.5 Ω Max.

-- Switch the ignition OFF.

If the specified value was Not obtained:

-- Check the circuit from the Secondary Air Injection (SAI) Pump Relay -J299- socket 2 (relay terminal 87) through fuse in Fuse Box B, out to the Secondary Air Injection (SAI) Pump Motor -V101- connector, terminal 2 for an open circuit or a short circuit to Ground. Refer to Wiring Diagrams for pin locations and fuse ID.

-- Check the wiring for an open circuit, high resistance or a short to Battery (+) or Ground.

-- Check the electrical connections for damage, corrosion, loose or broken terminals.

-- If necessary, repair the faulty wiring connection and replace fuse if blown.

If the specified value was obtained:
