TEST
5 WARNING: Before performing this test, to avoid personal injury allow the
exhaust manifold and related components to cool down to a safe tempera-
ture.
Turn the ignition off.
Disconnect the Air Injection Tube from the Exhaust one-way valve.
Turn the ignition on.
Using the DRBIII , actuate the Air Injection Pump Relay.
NOTE: When the Air Injection Pump is actuated, forced air should come out
of the opening of the Air Injection Pump Tube.
Does forced air come out of the Air Injection Pump Tube.
Yes → Replace the Exhaust one-way valve.
→ Go To 6
No
6 Turn the ignition off.
Disconnect the Air Injection Pump Motor harness connector.
Turn the ignition on.
Using the DRBIII, actuate the Air Injection Pump Relay.
Using a 12-volt test light connected to ground, probe the Air Injection Pump Relay
Output circuit in the Air Injection Pump Motor harness connector.
Does the test light illuminate brightly?
Yes → Go To 7
→ Go To 8
No
7 Turn the ignition off.
Disconnect the Air Injection Pump Motor harness connector.
Using a 12-volt test light connected to battery voltage, probe the Air Injection Pump
Motor ground circuit.
Does the test light illuminate brightly?
Yes → Replace the Air Injection Pump Motor.
→ Repair the open in the Air Injection Pump Ground circuit.
No
8 Turn the ignition off.
Disconnect the Air Injection Pump Relay harness connector.
Turn the ignition on.
