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.

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.
