ISO-9141 & KWP2000 Isolation Cable


This cable is designed to breakout only those signals that are defined for ISO-9141 & KWP2000. ISO-9141 & KWP2000 are common on Non-USA vehicles prior to 2008.

Prior to 2008, many manufacturers inserted non-OBDII compliant signals in to the OBDII connector for their own purposes. This cable ensures that none of these signals will result in an issue.

Does your 9141/KWP2000 vehicle need this cable? Most likely not. However, if your vehicle has signals in positions other than those described below, this cable may be prudent.

This cable breaks out the following

Male Connector Pin
Female Connector Pin
4,5 4,5
Vehicle Ground
16 16
+12 Battery
7,15 7,15
Data Signals

Pins that are isolated: 1,2,3,6,8,9,10,11,12,13 & 14

Cable length connector end to connector end: 14.25" or 36cm
Pin 16 is internally fused at the male end.

While this cable can be used on any vehicle which uses ISO-9141 or KWP2000, it is primarily for those vehicles which have non-standard implementations of the OBDII, such that vehicle manufacturers have inappropriately used connector pin signals for proprietary uses.

Most foreign vehicles manufactured prior to 2007 typically use ISO-9141. The KWP2000 protocol is less used and is a variation of ISO-9141.
