Is there battery voltage?

YES -Go to step 12.

NO -Repair open in the BLK/YEL wire between the No. 14 (10 A) fuse in the under-dash fuse/relay box
and the A/C compressor clutch relay socket.

12. Turn the ignition switch OFF.

13. Reinstall the A/C compressor clutch relay.

14. Make sure the A/C switch is OFF.

15. Turn the ignition switch ON (II).

16. Using the backprobe set, measure the voltage between the No. 18 terminal of ECM/PCM connector E

(31P) and body ground with the ECM/PCM connectors connected.

Is there battery voltage?

YES -Check for loose wires or poor connections at ECM/PCM connector E (31P). If the connections are
good, substitute a known-good ECM/PCM, and recheck. If the symptom/indication goes away, replace
the original ECM/PCM (see ECM/PCM REPLACEMENT ).

NO -Repair open in the wire between the A/C compressor clutch relay and the ECM/PCM.

17. Disconnect the jumper wire.

18. Disconnect the A/C compressor clutch 1P connector.

19. Check for continuity between the No. 1 terminal of the A/C compressor clutch relay 4P socket and the

No. 1 terminal of the A/C compressor clutch 1P connector.

Is there continuity?

YES -Check the A/C compressor clutch clearance, and the A/C compressor clutch field coil (see A/C
COMPRESSOR CLUTCH CHECK ).

NO -Repair open in the wire between the A/C compressor clutch relay socket and the A/C compressor
clutch.

A/C PRESSURE SWITCH CIRCUIT TROUBLESHOOTING

NOTE:



Do not use this troubleshooting procedure if any of these items are
working properly with the A/C switch ON; A/C condenser fan, radiator fan
and A/C compressor, or the heater does not work. Refer to the SYMPTOM
TROUBLESHOOTING INDEX.

1. Turn the ignition switch ON (II).

2. Turn the blower switch on, and check for blower motor operation.

Does the blower motor run correctly on all speeds?

YES -Go to step 3.

NO -Troubleshoot the blower motor circuit (see DTC 12: A PROBLEM IN THE BLOWER MOTOR
CIRCUIT ).

3. Disconnect the A/C pressure switch 2P connector.

4. Turn the ignition switch ON (II).

5. Measure the voltage between the No. 2 terminal of the A/C pressure switch 2P connector and body

ground.

Is there 5 V or more?

YES -Go to step 6.

NO -Go to step 14.

6. Turn the ignition switch OFF.

7. Check for continuity between the No. 1 and No. 2 terminals of the A/C pressure switch.



Before doing symptom troubleshooting, do the self-diagnostic function
(see RESETTING THE SELF-DIAGNOSTIC FUNCTION ).
