9. Check for continuity between body ground and theclimate control unit 32P connector terminals No. 10
and No. 12 individually.
Repair short to body ground in the wire(s)
between the climate control unit and the mode
control motor.
Go to step 10.
10. Test the mode control motor (see page 21-73).
Substitute a known-good climate control unit,
and recheck. If the symptom/indication goes away,
replace the original climate control unit.
Replace the mode control motor (see page
21-73), or repair the mode control linkage or
doors. 1. Clear the DTC with the HDS.
2. Turn the ignition switch to LOCK (0), and then turn
to ON (II).
3. Do the self-diagnostic with the HDS (see page 21-10) or climate control unit (see page 21-11).
4. Check for DTCs.
Go to step 5.
Intermittent failure, check for loose wires or
poor connections on the blower motor circuit.
5. Turn the ignition switch to LOCK (0).
6. Check the No. 9 (40 A) fuse in the under-hood fuse/relay box, and the No. 36 (10 A) fuse in the
under-dash fuse/relay box.
Go to step 7.
Replace the fuses, and recheck. If the fuses
blow again, check for a short in the No. 9 (40 A) and
No. 36 (10 A) fuses circuit.
7. Connect the blower motor 2P connector terminal No. 2 to body ground with a jumper wire.

away with a known-good ECM/PCM, replace the
original ECM/PCM (see page 11-228).
7. Turn the ignition switch to LOCK (0). 8. Measure the voltage between the radiator fan relay
4P socket terminal No. 1 and body ground.
Go to step 9.
Replace the under-hood fuse/relay box

A/C Compressor Clutch Circuit Troubleshooting
A/C COMPRESSOR CLUTCH RELAY 4P SOCKET
NOTE:
 It is normal for the A/C compressor to turn off under certain conditions, such as low idle, high engine
coolant temperature, or hard acceleration.
 Do not use this troubleshooting procedure if the fans are also inoperative with the A/C on. Refer to the
symptom troubleshooting index.
 Before doing any symptom troubleshooting, check for powertrain DTCs (see page 11-3).
1. Check the No. 20 (7.5 A) fuse in the under-hood fuse/relay box, and the No. 36 (10 A) fuse in the
under-dash fuse/relay box.
Go to step 2.
Replace the fuses and recheck. If the fuses
blow again, check for a short in the No. 20 (7.5 A)
and No. 36 (10 A) fuses circuit.
2. Connect the HDS to the DLC.
3. Start the engine.
4. Turn on the A/C.
5. Using the HDS, confirm the following values in the PGM-FI Data List at idle.
ECT Sensor 2 80 100 °C (176 212 °F)
TP Sensor About 0.5 V at idle
RPM More than 670
A/C Switch ON
A/C Clutch ON
A/C Pressure
Sensor 196 455 kPa (28 455 psi)
Go to step 6.
Troubleshoot the value that is not within the
specifications. 6. Turn the ignition switch to LOCK (0).
7. Remove the A/C compressor clutch relay from the
under-hood fuse/relay box, and test it (see page
22-70).
Go to step 8.
Replace the A/C compressor clutch relay.
8. Measure the voltage between the A/C compressor clutch relay 4P socket terminal No. 1 and body
ground.
Go to step 9.
Replace the under-hood fuse/relay box
(see page 22-65).
Ar e t he f uses OK ?
Are all the values within specif ications? Is the relay OK ?
Is there battery voltage?

Tips and Precautions
Before Troubleshooting
Handling Connectors
22-3
General Troubleshooting Information
A A A
A
1. Check applicable fuses in the appropriate fuse/relay box.
2. Check the battery for damage, state of charge, and clean and tight connections.
 Do not quick-charge a battery unless the battery ground cable has been
disconnected, otherwise you will damage
the alternator diodes.
 Do not attempt to crank the engine with the battery ground cable loosely
connected or you will s everely damage the
wiring.
 Make sure the connectors are clean and have no loose wire terminals.
 Make sure multiple cavity connectors are packed with dielectric grease (except watertight connectors).
 All connectors have push-down release type locks (A).  Some connectors have a clip on their side used to
attach them to a mount bracket on the body or on
another component. This clip has a pull type lock.
 Some mounted connectors cannot be disconnected unless you first release the lock and remove the
connector from its mount bracket (A).
 Never try to disconnect connectors by pulling on their wires; pull on the connector halves instead.
 Always reinstall plastic covers.
 Before connecting connectors, make sure the terminals (A) are in place and not bent.
