NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION
. For appropriate wiring diagram, see WIRING DIAGRAMS
at end of article.
- Connect jumper wire between terminal No. 3 (White/Tan wire) and terminal No. 4 (Pink/Dark Blue wire) of brakelight switch 6-pin connector (on brake pedal bracket). Check if any brakelights come on. If any brakelight is on, replace brakelight switch. Perform VERIFICATION PROCEDURE VER-1.
- If brakelights are off, access multifunction switch 24-pin connector. See Fig 1 . Backprobe terminal No. 14 (White/Tan wire) of multifunction switch 24-pin connector. If voltage is less than 10 volts, repair open White/Tan wire. Perform VERIFICATION PROCEDURE VER-1.
- If voltage was more than 10 volts, backprobe terminal No. 12 (Black/Red wire) of multifunction switch 24-pin connector. If voltage is less than 10 volts, replace multifunction switch. Perform VERIFICATION PROCEDURE VER-1. If voltage is more than 10 volts, backprobe terminal No. 15 (Dark Green/Red wire) of multifunction switch 24-pin connector.
- If voltage is less than 10 volts, replace multifunction switch. Perform VERIFICATION PROCEDURE VER-1. If voltage is more than 10 volts, disconnect light outage module 14-pin connector. See Figure . Check connector condition, and clean or repair connector as necessary.
- Check voltage on terminal No. 2 (Dark Green/Red wire) of light outage module 14-pin connector. If voltage is more than 10 volts, replace light outage module. Perform VERIFICATION PROCEDURE VER-1. If voltage is less than 10 volts, repair open Dark Green/Red wire and Brown/Red wire. Perform VERIFICATION PROCEDURE VER-1.
