+ | ===== BASIC TESTING of Turn Signal Wiring ===== | ||
+ | ==== For 1991 - 2013 Models ==== | ||
+ | Disconnect the Turn Signal Module from the wiring harness connector. Testing will be done on that wiring harness connector.\\ | ||
+ | For 1991-2003, the module is under the seat. For 2004-2013, the battery must be removed to withdraw the module located under the battery. | ||
+ | |||
+ | Look at the [[techtalk:evo:elec03#turn_signal_modules|wiring diagram]] for your module. Identify the FEED OUT & SWITCH IN pin numbers as shown on the diagram. | ||
+ | |||
+ | Identify the two wires (BROWN wire for RIGHT-side & VIOLET wire for LEFT-side) that feed power to the lights. Find the two wires (WHITE/BROWN wire for RIGHT-side & WHITE/VIOLET wire for LEFT-side) that are incoming from the handlebar switches. | ||
+ | |||
+ | The connector pin with incoming power is Pin2, Accessory Power, using an ORANGE wire or ORANGE/White or GREY wire. | ||
+ | |||
+ | **BEING VERY CAREFUL** not to short any other pins:\\ | ||
+ | With the TS module disconnected and the Keyswitch **ON**, CAREFULLY put a jumper __BRIEFLY__ between Pin2 (Power into the module) and the pin that is identified as RIGHT FEED OUT (BROWN wire). The RIGHT TS lights (both front & rear) & indicator should light up. | ||
+ | |||
+ | Now, CAREFULLY move that jumper __BRIEFLY__ between Pin2 (Power into the module) and the pin that is identified as LEFT FEED OUT (VIOLET wire). The LEFT TS lights (both front & rear) & indicator should light up. | ||
+ | |||
+ | \\ | ||
+ | |||
+ | Now you need a multimeter to check the incoming signal from the handlebar switches. Set the meter to 20v DC voltage. Place the BLACK probe on a good ground. The connector will have a BLACK wire for ground on Pin1 (for rigid mount models) or Pin12 (for rubbermount modules). See the wiring diagram. | ||
+ | |||
+ | With the TS module disconnected and the Keyswitch **ON**, CAREFULLY put the RED meter probe on the pin identified as RIGHT SWITCH IN (WHITE/Brown wire). Press the RIGHT-side TS Switch, then check the meter to see if it is getting the 12v input signal. | ||
+ | |||
+ | Move the RED meter probe to the pin identified as LEFT SWITCH IN (WHITE/Violet wire). Press the LEFT-side TS Switch, then check the meter to see if it is getting the 12v input signal. | ||
+ | |||
+ | \\ | ||
+ | |||
+ | |||
+ | ==== For 2014 - 2021 Models ==== | ||
+ | ONLY THE OUTPUT wiring to the Turn Signal lights will be tested. Because the handlebar switches use the CANbus to communicate with the BCM, it cannot be simply tested. | ||
+ | |||
+ | Disconnect the Body Control Module (BCM) from the wiring harness connector. Testing will be done on that wiring harness connector. | ||
+ | |||
+ | All the BCMs use the following pins for power to the TS lights:\\ | ||
+ | (Look at the [[techtalk:evo:elec03#turn_signal_modules|wiring diagram]].)\\ | ||
+ | Front Right - PinJ2 - BLUE/Orange wire\\ | ||
+ | Front Left -- PinJ4 - BLUE/Pink wire\\ | ||
+ | Rear Right -- PinK2 - BLUE/Brown wire\\ | ||
+ | Rear Left --- PinK4 - BLUE/Violet wire\\ | ||
+ | |||
+ | Pin1 has constant BATTERY POWER - **BE VERY CAREFUL HERE!** This power is fused thru the Main Fuse which will allow **40amps** of power to flow before blowing. **BE VERY CAREFUL** not to short this pin to ground! | ||
+ | |||
+ | With the TS module disconnected and the __KEYSWITCH OFF__, CAREFULLY put a jumper __BRIEFLY__ between Pin1 (Power into the module) and one of the above identified pins. As power is applied to each pin, the identified TS light should be lit. | ||
