Hello All,
I have a 2004 Freelander SE KV6 Automatic that is not feeling well.
Both service lights are on. When driving, it will drive normally (quite well actually) for anywhere from 1 minute to 10 minutes, then a flashing F - 4 code on the LCD with the HDC warning lights lit up. The transmission goes into single speed limp mode.
I've done a fair bit of googling regarding the problems which has lead me to suspect that it is an electrical / communications problem or a sensor problem that is bringing down the network. Suspects range from the brake switch to the ECU cooling fan to a dodgy hub speed sensor. I've hooked up a generic ODD II reader and retrieved the following list of codes:
MIL DTC
P1646 CAN link to auto gearbox ECU. Implausible signal/condition
Technical Service Bulletins:
There are currently no TSBs for P1646.
Stored Codes
P0222 Throttle/Pedal Position Sensor B Circuit Low Input
P0500 Vehicle Speed Sensor A
P0606 ECM / PCM Processor
P1605 Internal EEPROM fault General fault
P1627 engine overspeed.Implausible signal/condition
P1646 CAN link to auto gearbox ECU.Implausible signal/condition
Technical Service Bulletins:
There are currently no TSBs for P1646.
P1775 Gearbox Fault
P1844 Engine RPM error flag set.
Any thoughts on a good place to start. I'm a fairly competent mechanic and electrician with a good set of tools.
I've started by installing a fresh battery and checked for obvious wire damage...
Cheers,
Paul in Victoria.
