TEST
3 Turn the ignition off.
Disconnect the IAC Motor harness connector.
Disconnect the Powertrain Control Module harness connectors.
Note: The following steps are checking for a short between the IAC Driver
Circuits.
Measure the resistance between the IAC #2 Driver circuit and #3, #4 Driver circuits.
Is the resistance below 5.0 ohms between any of the Drivers?
Yes → Repair the IAC Driver Circuits shorted together.
→ Go To 4
No
4 Turn the ignition off.
Disconnect the IAC Motor harness connector.
Disconnect the Powertrain Control Module harness connectors.
Note: The following steps are checking for a short between the Driver
Circuits.
Measure the resistance between the IAC #3 Driver circuit and the #4 Driver circuit.
Is the resistance below 5.0 ohms?
Yes → Repair the IAC Driver Circuits shorted together.
→ Go To 5
No
5 Turn the ignition off.
Disconnect the IAC Motor harness connector.
Disconnect the Powertrain Control Module harness connector.
Remove the ASD Relay.
Using a jumper wire, jumper between the Fused B+ circuit and ASD Relay Output
circuit in the PDC.
Turn the ignition on.
Measure the voltage of each of the IAC Driver circuit.
Is the voltage above 1.0 volt at any IAC Driver circuit?
Yes → Repair the IAC Driver circuit(s) for a short to voltage.
→ Go To 6
No
6 Turn the ignition off.
Disconnect IAC Motor harness connector.
Disconnect the PCM harness connector.
Repeat each measurement for each IAC Driver circuit.
Measure the resistance of each IAC Driver circuit to ground.
Is the resistance below 5.0 ohms at any IAC Driver circuit?
Yes → Repair the short to ground in the IAC Driver circuit(s).
→ Go To 7
No
