   Voltage: 

   Intermittently changes between approx. 0V and approx. 4.5V. 

OK or NG 

1. OK: GO TO  3.
2. NG: GO TO 2.

Check the following items:

• Combination meter

  Refer to "METERS AND GAUGES ".

• Harness for short or open between TCM and combination meter
• ABS actuator and electric unit (without TCS) or ABS/TCS control unit (with TCS)

  Refer to "ON BOARD DIAGNOSTIC SYSTEM DESCRIPTION " (Without TCS) or "ON BOARD DIAGNOSTIC SYSTEM DESCRIPTION " (With TCS).

• Harness for short or open between combination meter and ABS actuator and electric unit (without TCS), or ABS/TCS control unit (with TCS).

OK or NG 

1. OK: GO TO 3.
2. NG: Repair or replace damaged parts.

Perform DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION PROCEDURE , .

OK or NG 

1. OK: INSPECTION END 
2. NG: GO TO 4.

1. Perform TCM input/output signal inspection.
2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector.

OK or NG 

1. OK: INSPECTION END 
2. NG: Repair or replace damaged parts.
