Test TC-15B: Speed Control Solenoid Circuits Or Speed Control Power Relay Circuits
NOTE:
Perform TEST TC-15A
before proceeding. For connector terminal identification, see CONNECTOR IDENTIFICATION
. To identify referenced circuits and terminals, see WIRING DIAGRAMS
.
- Turn ignition off. Using an external ohmmeter, check resistance of S/C brake switch output circuit (Dark Blue/Red wire) between brakelight switch connector and S/C servo connector. If resistance is more than 5 ohms, repair open switched S/C brake switch output circuit and perform TEST SC-VER . If resistance is 5 ohms or less, go to next step.
- Check brakelight switch adjustment. Adjust brakelight switch as necessary and perform TEST SC-VER . If brakelight switch is adjusted properly, replace brakelight switch and perform TEST SC-VER .
