Diagnostic Procedure

With CONSULT-II 

1. Turn ignition switch "ON". (Do not start engine.)
2. Select "DATA MONITOR" mode for "TRANSMISSION" with CONSULT-II.
3. Move selector lever to "P""R""N""D" and "L" position and check the value of "PNP SW A""PNP SW B""PNP SW C""PNP SW PA" and "PNP SW PN".

OK or NG 

OK: GO TO  5.

NG: GO TO 2.

1. Turn ignition switch "OFF".
2. Disconnect the PNP switch connector.
3. Turn ignition switch "ON". (Do not start engine.)
4. Check the voltage between PNP switch connector terminal 1 and ground.

7. If OK, check harness for short-circuit to ground or power source.

OK or NG 

OK: GO TO 3.

NG: Check the following. If any items are damaged, repair or replace damaged parts.

• Harness for short or open between ignition switch and PNP switch
• Ignition switch and fuse

  Refer to "POWER SUPPLY ROUTING CIRCUIT ".

1. Turn ignition switch "OFF".
2. Disconnect the TCM connector and PNP switch connector.
3. Check continuity between TCM connector terminals 24, 31, 32, 43 and ground.

   Connector	Terminal	Condition	Continuity
   E142	24 - Ground	Selector lever: "P""R" and "L" position	Yes
   		Other than the above	No
   	31 - Ground	Selector lever: "R""N""D" and "L" position	Yes
   		Other than the above	No
   	32 - Ground	Selector lever: "D" and "L" position	Yes
   		Other than the above	No
   	43 - Ground	Selector lever: "P""N" and "L" position	Yes
   		Other than the above	No

4. If OK, check the following.
   • Harness for short-circuit to ground or power source.
   • Open or short-circuit in the harness between combination meter and TCM.

OK or NG 

OK: GO TO  5.

NG: GO TO 4.

Check the following.

• Open or short-circuit in the harness between TCM and PNP switch A, B, C, PA.
• Open or short-circuit in the harness for ground of PNP switch.
• PNP switch. Refer to "COMPONENT INSPECTION ".

OK or NG 

OK: GO TO 6.

NG: Repair or replace damaged parts.

Perform "DTC Confirmation Procedure". Refer to "DTC CONFIRMATION PROCEDURE ".

OK or NG 

OK: INSPECTION END 

NG: GO TO 6.

1. Check TCM input/output signal. Refer to "TCM INPUT/OUTPUT SIGNAL REFERENCE VALUES ".
2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector.

OK or NG 

OK: INSPECTION END 

NG: Repair or replace damaged parts.
