2003 Smart 450 Passion 700 cc petrol. Car had below faults codes when it arrived:
P2022 Clutch system fault
P203C Actual position of turning angle sensor
Diagnostics kit WinStar Magus version Z0803.
Owner had attempted repair of thin yellow cable (either to pin 3 or 5) leading to transmission gear change motor. He had difficulties getting solder to wet the oxidised copper strands so I sorted that out by wetting the strands in hydrochoric acid to remove the black oxidised layer. Made cable good as new by soldering and added double heat shrink sleeve for insulation and protection.
Proceeded then to carry out gear change adaptation using WinStar. Gear change adaptation did not complete. Heard two or three clonks then nothing. Winstar did not complete gear change adaptation. Reports gear change adaptation not successful and fault code P2035 Turning angle sensor adaptation.
I then proceeded to check all cables from engine control unit to transmission actuators and sensors. Tested the 17 cables twice, first by measuring resistance using multimeter. Secondly by passing current through using a 55 Watts head lamp bulb and power source an old fashioned 12 Volt battery charger. Measured amps around 3.5 A. All tests of transmission cable harness were good.
Car battery is fully charged and being kept on charge with a Lidl intelligent charger.
Tried a brand new clutch actuator but no change. I removed gear change motor and confirmed I can turn the gear change wheels manually hence not seized. Gear change motor does also turn when hot wired to pins 1 & 6.
Looking for some guidance. Obviously my next step will be to check drum rotation sensor and perhaps borrow that one and gear change motor from my Smart Cabrio.
PS. Lucky the forum is back up running. Thanks a lot OMA & al.
