Voltage Suppressor Test
12. Test the voltage suppressor wire assembly.
12.1. Disconnect the voltage suppressor assembly (17) from the relay coil terminals
.
12.2. Using a multimeter set to the diode test function (ç), place the black (–) probe of the multimeter on the
voltage suppressor red wire (25)
. Place the red (+) probe on the blue wire
(26). The multimeter should indicate an overlimit with no tone emitted.
12.3. Reverse the multimeter probes and observe the multimeter. The multimeter should continue to indicate an
overlimit with no tone emitted.
12.4. If a tone is emitted (indicating a closed circuit) then the voltage suppressor has failed closed and should
be replaced.
13. Test the brake light relay coil.
13.1. Remove the voltage suppressor wire assembly (17) from the relay (10) coil terminals
13.2. Using a multimeter set to 200 ohms, place the black (–) probe of the multimeter on one of the relay coil
terminals
. Place the red (+) probe on the other relay coil terminal. The coil
resistance should be between 139 and 171 ohms. If the reading is incorrect, replace the relay.
Removal, Section 12, Page 12-31.
13.3. Restore the wiring to the original configuration (not bypassed).
