Hi all...
Picked up a 2007 GS with a few issues, the biggest one being the Terrain response system.
The good news is that the diff/haldex seem ok, ( a jacked up rear wheel can spin). Tested the pump on multi meter (4 ohm) and heard the pump whur - up briefly
I've replaced the haldex/diff module ( known good) to no effect. wiring good/clean connector and no visible cable chafing under the car?
I've read a few threads suggesting other modules might be causing this issue ( The terrain amber light comes on immediately when the car ignition is on, and doesn't go off) :-
ABS - 0136 lost communication with diff
BCM - 0136 lost communication with diff
ATM - 0136 lost comms...
I think my Icar scanner is telling me DSC & HDS are not activated......when i press either of these buttons in the car, the scanner shows they will activate for a split second, then default to inactive again.
Some threads talk of the ABS module, though ABS reports tone wheels fine ( monitored during a test drive and have no codes)
SAS has no faults, and has been calibrated a few times (steer full left - then right - then to centre) and has sensible figures for angle.
Not sure what the BCM has to do with Terrain response, but seems neither the BCM or the ABS can or won't talk with the diff module
The infotainment module/system requires coding to the car, as the unit keeps telling me the VIN doesn't match.
The instrument pack reckons the odometer has been altered, though MOT'S support the reading?
The battery is brand new, and the alternator supplied a good voltage 14.6v ish
The engine is sweet, but think the throttle body may have issues, with P02E9 - P02E1 (missing actuator teeth?) though haven't pulled the unit yet.
Before I start looking for broken/chafed wires to cure the p0136 code , has any of the forum experienced the 1 amigo terrain warning.
Any help appreciated.
