, Fuel preparation, injection

• Secondary Air Injection (AIR) pump relay (under cover, left at bulkhead) must trigger and the Secondary Air Injection (AIR) pump motor -V101- must run.

A - If relay does not trigger:

• Check voltage supply of the Secondary Air Injection (AIR) pump relay. Refer to Checking voltage supply of Secondary Air Injection (AIR) pump relay .
• Check activation of the Secondary Air Injection (AIR) pump relay. Refer to Check activation of the Secondary Air Injection (AIR) pump relay .

B - If relay triggers, but Secondary Air Injection (AIR) pump does not run:

• Check voltage supply of the Secondary Air Injection (AIR) pump motor. Refer to Check voltage supply of the Secondary Air Injection (AIR) pump motor .
