DTC Troubleshooting (cont’d) A/C Signal Circuit Troubleshooting
37. Check for Temporary DTCs or DTCs with the HDS.
Check for poor connections or loose
terminals at the A/C pressure sensor and the ECM/
PCM. If the ECM/PCM was updated, substitute a
known-good ECM/PCM (see page 11-7), then go to
step 34. If the ECM/PCM was substituted, go to step
1.
If the ECM/PCM was updated, troubleshooting
is complete. If the ECM/PCM was substituted,
replace the original ECM/PCM (see page 11-228). If
any other Temporary DTCs or DTCs are indicated,
go to the indicated DTC’s troubleshooting. 1. Start the engine, and let it idle.
2. Turn the blower switch on.
3. Turn the A/C switch on.
4. Check the A/C CLUTCH in the DATA LIST with the
HDS.
Go to step 5.
Do the A/C system test (see page 21-99).
5. Check the A/C system.
The air conditioning system circuit is OK.
Go to step 6.
6. Turn the ignition switch to LOCK (0).
7. Turn the ignition switch to ON (II).
8. Activate the A/C CLUTCH in the INSPECTION MENU with the HDS.
Do the A/C system test (see page 21-99).
Go to step 9.
9. Turn the ignition switch to LOCK (0).
10. Jump the SCS line with the HDS.
11. Disconnect ECM/PCM connector A (44P).
12. Turn the ignition switch to ON (II).

13. Momentarily connect ECM/PCM connector terminalA14 to body ground with a jumper wire s everal
times.
Update the ECM/PCM if it does not have the
latest software (see page 11-227), or substitute a
known-good ECM/PCM (see page 11-7), then
recheck. If the symptom/indication goes away with
a known-good ECM/PCM, replace the original ECM/
PCM (see page 11-228).
Check for poor connections or loose terminals
attheA/CclutchrelayandtheECM/PCM.Ifthe
connections and the terminals are OK, check the
A/C compressor clutch relay (see page 22-70),
repair open in the wires between the ECM/PCM
(A14), the A/C compressor clutch relay, and other
A/C systems parts. 1. Start the engine, and let it idle.
2. Monitor the ALTERNATOR in the DATA LIST with
the HDS.
3. Check if the indicated percentage varies when the headlight switch is turned on.
The alternator signal circuit is OK.
Go to step 4.
4. Turn the headlight switch and ignition switch to LOCK (0).
5. Jump the SCS line with the HDS.
6. Disconnect the alternator 4P connector.
7. Disconnect ECM/PCM connector B (44P).
8. Check for continuity between body ground and ECM/PCM connector terminal B43.
Repair short in the wire between the ECM/
PCM (B43) and the alternator.
Update the ECM/PCM if it does not have the
latest software (see page 11-227), or substitute a
known-good ECM/PCM (see page 11-7), then
recheck. If the symptom/indication goes away with
a known-good ECM/PCM, replace the original ECM/
PCM (see page 11-228).
