mc Posted March 13, 2009 Share Posted March 13, 2009 I cant find any info about it, so can anyone tell me where the relay for the indicators is located cheers! Mike Quote Link to comment Share on other sites More sharing options...
Dicky Posted March 13, 2009 Share Posted March 13, 2009 Don’t think it’s got one. I believe a unit called the BCM (Body control Module) takes the turn signal info from the indicator stalk on the wheel and powers the indicator lamps itself. I also believe the clicking indicator sound is also controlled by the BCM which powers an audible sounder from one of its outputs. If that’s not the right answer it does sound quite good. No doubt someone will put us both right on the subject. Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted March 13, 2009 Share Posted March 13, 2009 System Description AKS000UC TURN SIGNAL OPERATION When the ignition switch is in the ON or START position, power is supplied through 10A fuse [No. 1, located in the fuse block (J/B)] to BCM (body control module) terminal 35, and through 10A fuse [No. 14, located in the fuse block (J/B)] to terminal 23 of the combination meter. Ground is supplied to BCM (body control module) terminal 8 through grounds E17, E43, and F152, and to combination meter terminals 10, 11 and 12 through grounds M30 and M66. LH Turn When the turn signal switch (combination switch) is moved to the LH position, the BCM (body control module) receives left turn signal by combination switch reading function (Refer to LT-159, "Combination Switch Reading Function" ). Power is supplied through BCM (body control module) terminal 22 to front turn signal lamp LH (part of the front combination lamp LH) terminal 2 (with xenon headlamp) to front turn signal lamp LH (part of the front combination lamp LH) terminal 1 (with halogen headlamp) to rear turn signal lamp LH (part of the rear combination lamp LH) terminal 2. Ground is supplied to the front turn signal lamp LH (part of the front combination lamp LH) terminal 1 through grounds E17, E43 and F152 (with xenon headlamp). Ground is supplied to the front turn signal lamp LH (part of the front combination lamp LH) terminal 4 through grounds E17, E43 and F152 (with halogen headlamp). Ground is supplied to the rear turn signal lamp LH (part of the rear combination lamp LH) terminal 4 through grounds T14, B6, B5 and D105. The BCM also supplies ground to unified meter and A/C amp terminals 1and 11 across the CAN communication lines. This input signal is processed by the unified meter control unit in the combination meter through the unified meter and A/C amp, which in turn supplies ground to the left turn signal indicator lamp. With power and ground supplied, the BCM controls the flashing of the LH turn signal lamps. RH Turn When the turn signal switch (combination switch) is moved to the RH position, the BCM (body control module) receives right turn signal by combination switch reading function (Refer to LT-159, "Combination Switch Reading Function" ) power is supplied through BCM (body control module) terminal 21 to front turn signal lamp RH (part of the front combination lamp RH) terminal 2 (with xenon headlamp) to front turn signal lamp RH (part of the front combination lamp RH) terminal 1 (with halogen headlamp) to rear turn signal lamp RH (part of the rear combination lamp RH) terminal 2. Ground is supplied to the front turn signal lamp RH (part of the front combination lamp RH) terminal 1 through grounds E17, E43 and F152 (with xenon headlamp). Ground is supplied to the front turn signal lamp RH (part of the front combination lamp RH) terminal 4 through grounds E17, E43 and F152 (with halogen headlamp). Ground is supplied to the rear turn signal lamp RH (part of the rear combination lamp RH) terminal 4 through y grounds T14, B6, B5 and D105. The BCM also supplies ground to unified meter and A/C amp terminals 1 and 11 across the CAN communication lines. This input is processed by the unified meter control unit in the combination meter through the unified meter and A/C amp, which in turn supplies ground to the right turn signal indicator lamp. With power and ground supplied, the BCM controls the flashing of the RH turn signal lamps. HAZARD LAMP OPERATION Power is supplied at all times to BCM (body control module) terminal 7 Quote Link to comment Share on other sites More sharing options...
mc Posted March 14, 2009 Author Share Posted March 14, 2009 Thanks for the replies, I was going to change the indicator bulbs to LEDs but then change the relay to get the correct flashing speed... looks a little more complicated now!
