INSPECTION PROCEDURE

PROCEDURE

1. CHECK INDICATOR LIGHT
(a) Inspect the indicator light condition by operating the P position switch.

Result





B -- INSPECT FUSE (P CON MAIN)
A -- Continue to next step.

2. CHECK WIRE HARNESS (TRANSMISSION CONTROL ECU - P POSITION SWITCH)




(a) Disconnect the T4 ECU connector.
(b) Disconnect the M11 switch connector.
(c) Measure the resistance of the wire harness side connector.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- REPLACE TRANSMISSION CONTROL ECU
3. INSPECT FUSE (P CON MAIN)




(a) Remove the P CON MAIN fuse from the engine room relay block.
(b) Measure the resistance of the fuse.
Standard resistance:
Below 1 Ohms
NG -- INSPECT FOR SHORT IN ALL COMPONENTS CONNECTED TO FUSE AND REPAIR OR REPLACE THEM IF NEEDED, AND REPLACE FUSE
OK -- Continue to next step.

4. CHECK WIRE HARNESS (TRANSMISSION CONTROL ECU - BATTERY)




(a) Disconnect the T4 ECU connector.
(b) Measure the voltage of the wire harness side connector.
Standard voltage:






OK -- REPLACE TRANSMISSION CONTROL ECU
NG -- Continue to next step.

5. CHECK WIRE HARNESS (TRANSMISSION CONTROL ECU - P POSITION SWITCH)




(a) Disconnect the T4 ECU connector.
(b) Disconnect the M11 switch connector.
(c) Measure the resistance of the wire harness side connectors.
Standard resistance:






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

6. CHECK WIRE HARNESS (P POSITION SWITCH - BATTERY)




(a) Disconnect the M11 switch connector.
(b) Measure the voltage of the wire harness side connector.
Standard voltage:






OK -- REPLACE P POSITION SWITCH
NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
