-
Secondary Air Injection (AIR) Pump Relay -2- (in 3-pin relay carrier, E-box plenum chamber) must engage and Secondary Air Injection (AIR)
Pump Motor -V101- must run
A - Secondary Air Injection (AIR) Pump Motor runs:
-
Check voltage supply of the Secondary Air Injection (AIR) pump relay.
-
Check activation of the Secondary Air Injection (AIR) pump relay.
B - Secondary Air Injection (AIR) Pump Motor does not run:
-
Check voltage supply of the Secondary Air Injection (AIR) pump motor.
Checking voltage supply of Secondary Air Injection (AIR) pump relay
-
Remove Secondary Air Injection (AIR) pump relay -2-.
-
