•  The TCS OFF switch is integrated with the cluster switch.
•  For the TCS OFF switch removal/installation, refer to CLUSTER SWITCH REMOVAL/INSTALLATION. (See CLUSTER SWITCH REMOVAL/INSTALLATION.)

1.  Disconnect the negative Lead-acid battery terminal. (See NEGATIVE LEAD-ACID BATTERY TERMINAL DISCONNECTION/CONNECTION.)

2.  Disconnect the cluster switch connector. (See CLUSTER SWITCH REMOVAL/INSTALLATION.)

3.  Attach the tester lead to the cluster switch wiring harness-side connector and inspect voltage or continuity according to the Terminal Voltage Table (Reference) on the table.

•  If not as specified, repair or replace the related wiring harness.
•  If as specified, replace the cluster switch. (See CLUSTER SWITCH REMOVAL/INSTALLATION.)
