How to Troubleshoot Circuits at the PCM

A
C A

NOTE: The PCM overwrites data and monitors the EVAP
system for about 30 minutes after the ignition switch is
turned to LOCK (0) or ACC (I). Jumping the SCS line
after turning the ignition switch to LOCK (0) or ACC (I)
cancels this function. Disconnecting the PCM during
this function, without jumping the SCS line first, can
damage the PCM.
1. Make sure the ignition switch is turned to LOCK (0), then jump the SCS line with the HDS.
2. Remove the cover (A).
3. Lift up the under-hood fuse/relay box (D).
4. Remove the coolant reservoir (E). Disconnect PCM connectors A, B, and C, and probe the terminals
from the terminal side of the connectors.
NOTE: PCM connectors A, B, and C have symbols
(A= , B= , C= ) embossed on them for
identification. 5. When diagnosis/troubleshooting is done at the
PCM connector, use the terminal test port (A) above
the terminal you need to check.
6. Connect one side of the patch cord’s terminals (A) to a commercially available digital multimeter (B),
and connect the other side cord’s terminals (C) to a
commercially available banana jack (Pomona
Electronics Tool No. 3563 or equivalent) (D).
7. Gently contact the pin probe (male) at the terminal test port from the terminal side. Do not force the
tips into the terminals.
 For accurate results, always use the pin probe (male).
 To prevent damage to the connector terminals, do not insert test equipment
probes, paper clips, or other substitutes as
they can damage the terminals. Damaged
terminals cause a poor connection and an
incorrect measurement.
 Do not puncture the insulation on a wire. Punctures can cause poor or intermittent
electrical connections.

The electronic control system consists of the powertrain control module (PCM), sensors, and solenoid valves.
Shifting and lock-up are electronically controlled for comfortable driving under all conditions.
The PCM receives input signals from sensors, switches, and other control units, processes data, and outputs signals
for the engine control system and the A/T control system. The A/T control system includes shift control, grade logic
control, clutch pressure control, and lock-up control.
The PCM switches the shift solenoid valves and the A/T clutch pressure control solenoid valves ON and OFF to control
gear selection and torque converter clutch lock-up.

A grade logic control system has been adopted to control shifting in D, and in S with automatic shift mode. The PCM
compares actual driving conditions with programmed driving conditions, based on the input from the accelerator
pedal position sensor, the throttle position sensor, the engine coolant temperature sensor, the barometric pressure
sensor, the brake pedal position switch signal, the output shaft (countershaft) speed sensor signal, and the shift l ever
position signal, to control shifting while the vehicle is ascending or descending a slope.

The PCM actuates A/T clutch pressure control solenoid valves A, B, and C to control the clutch pressure. When shifting
between lower and higher gears, the clutch pressure regulated by A/T clutch pressure control solenoid valves A, B,
and C engages and disengages the clutch smoothly.
The PCM receives input signals from the various sensors and the switches, processes data, and outputs current to A/T
clutch pressure control solenoid valves A, B, and C.

Shift solenoid valve E controls the hydraulic pressure to switch the lock-up shift valve and lock-up ON and OFF. When
the PCM actuates shift solenoid valve E and A/T clutch pressure control solenoid valve A to start lock-up. A/T clutch
pressure control solenoid valve A regulates and applies hydraulic pressure to the lock-up control valve to control the
amount of lock-up. The lock-up mechanism operates in D and S (2nd, 3rd, 4th, and 5th gears).

DTC Troubleshooting (cont’d)
Problem in ATF Temperature
Sensor Circuit
NOTE:
 Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review
General Troubleshooting Information (see page 14-3).
 This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the
transmission.
1. Turn the ignition switch to ON (II).
2. Check the ATF Temp Sensor in the Data List with the HDS.
Record the ATF temperature. Leave the
engine off for at least 30 minutes, then go to step 3.
Record the ATF temperature. Test the stall
speed RPM (see page 14-210) three times, then go
to step 3.
3. Check the ATF Temp Sensor in the Data List with the HDS.
Leave the engine off for at least 30 minutes,
then go to step 4.
Replace the ATF temperature sensor
(see page 14-229), then go to step 6.
4. Check the ECT Sensor in the Data List with the HDS.
Go to step 5.
Leave the engine off until ECT Sensor reads
the same as the outside air temperature, then go to
step 5. 5. Check the ATF Temp Sensor in the Data List with
the HDS.
Go to step 13.
Replace the ATF temperature sensor
(see page 14-229), then go to step 6.
6. Turn the ignition switch to ON (II).
7. Clear the DTC with the HDS.
8. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).
9. Allow the engine coolant temperature to cool to the outside air temperature.
10. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on),
and wait for at least 20 seconds, then drive the
vehicle at speeds over 31 km/h (19 mph) for at least
5 minutes.
11. Check for Temporary DTCs or DTCs with the HDS.
Check for poor connections or loose
terminals between the ATF temperature sensor and
thePCM,thengotostep1.
Go to step 12.
