INSPECTION PROCEDURE

NOTICE:
Inspect the fuses for circuits related to this system before performing the following inspection procedure.

PROCEDURE

1. CHECK WIRE HARNESS AND CONNECTOR (ACC VOLTAGE)

(a) Disconnect the D42 control unit relay assembly connector.









(b) Measure the voltage according to the value(s) in the table below.

Standard Voltage:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

2. CHECK WIRE HARNESS AND CONNECTOR (CONTROL UNIT RELAY ASSEMBLY - BODY GROUND)

(a) Disconnect the D42 control unit relay assembly connector.

(b) Measure the resistance according to the value(s) in the table below.

Standard Resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

3. INSPECT P SWITCH (FLOOR SHIFT SHIFT LEVER HOUSING)

(a) Inspect the P switch (floor shift shift lever housing) Shift Lever.

NG -- REPLACE P SWITCH (FLOOR SHIFT SHIFT LEVER HOUSING) Disassembly
OK -- Continue to next step.

4. CHECK WIRE HARNESS AND CONNECTOR (CONTROL UNIT RELAY ASSEMBLY - P SWITCH (FLOOR SHIFT SHIFT LEVER HOUSING)

(a) Disconnect the D42 control unit relay assembly connector.

(b) Disconnect the D28 P switch (floor shift shift lever housing) connector.

(c) Measure the resistance according to the value(s) in the table below.

Standard Resistance (Check for Open):





Standard Resistance (Check for Short):





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

5. CHECK WIRE HARNESS AND CONNECTOR (P SWITCH (FLOOR SHIFT SHIFT LEVER HOUSING) - BODY GROUND)

(a) Disconnect the D28 P switch (floor shift shift lever housing) connector.

(b) Measure the resistance according to the value(s) in the table below.

Standard Resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

6. INSPECT KEY INTER LOCK SOLENOID

(a) Disconnect the D60 key inter lock solenoid connector.









(b) Measure the resistance according to the value(s) in the table below.

Standard Resistance:





NG -- REPLACE KEY INTER LOCK SOLENOID Disassembly
OK -- Continue to next step.

7. CHECK WIRE HARNESS AND CONNECTOR (CONTROL UNIT RELAY ASSEMBLY - KEY INTER LOCK SOLENOID)

(a) Disconnect the D42 control unit relay assembly connector.

(b) Disconnect the D60 key inter lock solenoid connector.

(c) Measure the resistance according to the value(s) in the table below.

Standard Resistance (Check for Open):





Standard Resistance (Check for Short):





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

8. CHECK WIRE HARNESS AND CONNECTOR (KEY INTER LOCK SOLENOID - BODY GROUND)

(a) Disconnect the D60 key inter lock solenoid connector.

(b) Measure the resistance according to the value(s) in the table below.

Standard Resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

OK -- REPLACE CONTROL UNIT RELAY ASSEMBLY Removal
