Secondary Air Injection Pump Motor, Checking

Secondary Air Injection Pump Motor, Checking

Special tools, testers and auxiliary items required

• Multimeter.

• Wiring diagram.

Test requirements

• Fuse (S130) OK.

• The Secondary Air Injection (AIR) Pump Relay (-J299-) OK.

• Battery voltage at least 12.5 V.

• All electrical consumers switched off.

• A/C switched off.

• The ignition switched off.

Test procedure

- Perform a preliminary check to verify the customers complaint. Refer to => [ Preliminary Check ] Preliminary Check.

Start diagnosis

- Install the protective body covers.

• A second technician must hold the lid securely while the rear lid gas-filled strut - 3 - is disengaged from the lower left joints.





- Using a screwdriver - 1 -, remove the retaining spring - 2 - and remove the gas-filled strut from the ball stud.

- Remove the power steering reservoir cap.

- Loosen the quick-release fasteners and remove the left engine compartment trim - 1 -.





- Reinstall the gas-filled strut back onto the ball studs.

- Disconnect the Secondary Air Injection (AIR) Pump Motor (-V101-) electrical harness connector - 3 -.





Checking voltage

- Using a Multimeter, check the Secondary Air Injection (AIR) Pump Motor (-V101-) electrical harness connector terminals 1 to 2 for voltage.

- Crank the engine.





- Switch the ignition off.

Specified value: battery voltage.

If the specified value was not obtained:

- Using a Multimeter, check the Secondary Air Injection (AIR) Pump Motor (-V101-) electrical harness connector terminal 2 to Ground (GND).





Specified value: battery voltage.

If the specified value was not obtained:

- Check the wiring connection from the Secondary Air Injection (AIR) Pump Relay (-J299-) socket 8 to the Secondary Air Injection (AIR) Pump Motor (-V101-) electrical harness connector terminal 2 for an open circuit or a short circuit.

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

- If necessary, repair the faulty wiring connection.

If the specified value was obtained:

Checking Ground (GND)

- Using a Multimeter, check the Secondary Air Injection (AIR) Pump Motor (-V101-) electrical harness connector terminal 1 to Ground (GND) for resistance.





Specified value: 1.5 ohms Max.

If the specification was not obtained:

- Check the wiring for a short circuit to each other, Battery (+), and Ground (GND).

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

- If necessary, repair the faulty wiring connection.

If no malfunction is found in the wiring and voltage supply was OK:

- Replace the Secondary Air Injection (AIR) Pump Motor (-V101-).

Assembly is performed in the reverse order of the removal, note the following:

Final procedures

After repair work, the following work steps must be performed in the following sequence:

1. Check the DTC memory. Refer to => [ Diagnostic Mode 03 - Read DTC Memory ] Diagnostic Mode 03 - Read DTC Memory.

2. If necessary, erase the DTC memory. Refer to => [ Diagnostic Mode 04 - Erase DTC Memory ] Clearing Diagnostic Trouble Codes.

3. If the DTC memory was erased, generate readiness code. Refer to => [ Readiness Code ] Readiness Code.
