STEP 12. Check for open circuit and short circuit to 
ground and harness damage between fuel pump relay 2 
connector B-24X (terminal No. 3) and fuel pump connector 
G-04 (terminal No. 5).
NOTE: Check harness after checking intermediate connectors 
D-111, E-111, F-07. If intermediate connectors are damaged, 
repair or replace them. After to GROUP 00E, Harness Connec-
tor Inspection 

P.00E-2

. Then check that the malfunction is elim-

inated.
Q: Is the harness wire in good condition?

YES : Go to Step 13.
NO :  Repair it. Then confirm that the malfunction symptom 

is eliminated.

STEP 13. Check connector D-132 at PCM for damage.
Q: Is the connector in good condition?

YES : Go to Step 14.
NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection 

P.00E-2

. Then confirm that the 

malfunction symptom is eliminated.

STEP 14. Measure the power supply voltage at PCM 
connector D-132.
(1) Disconnect the connector D-132 and measure at the 

harness side.

(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between terminal No. 16 and ground.

• Voltage should measure battery positive voltage.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is battery positive voltage (approximately 12 volts) 

present?
YES : 
Replace the PCM. Then confirm that the malfunction 

symptom is eliminated.

NO :  Repair harness wire between fuel pump relay 1 

connector B-19X (terminal No. 2) and PCM connector 
D-132 (terminal No. 16) because of open circuit. Then 
confirm that the malfunction symptom is eliminated.

COMMENT

• If the selector lever is moved to "P" or "N" range 

and the ignition switch is turned to "START" posi-
tion, battery positive voltage is supplied to PCM 
(terminal No. 51) through the ignition switch and 
transmission range switch. Because of this, the 
PCM detects that the engine is cranking. 

• The transmission range switch detects the trans-

mission range (P, N or other ranges) and con-
verts it to a voltage signal (high or low). Then the 
transmission range switch sends that signal to 
the PCM. 

If the selector lever is moved to "P" or "N" range 
with the ignition switch turned on (except 
"START" position), continuity will exist between 
the PCM and ground through the transmission 
range switch and starter motor. The terminal volt-
age of the PCM will become low. If the selector 
lever is moved to the other ranges, continuity will 
be lost between the PCM and ground. The termi-
nal voltage of the PCM will become high. 

.

TROUBLESHOOTING HINTS (The most likely 
caused for this code to be set are: )

• Malfunction of the ignition switch.

• Malfunction of the transmission range switch.

• Improper connector contact, open circuit or short-

circuit in the harness wire.

• Malfunction of the PCM.
