F18 - ECU KWP2000 Communication Error

Situation: Indication "F18" flickering, Drive Operations disabled.

Possible Cause: Faulty ECU, faulty gateway, faulty harness.

How the error code is triggered: When the KWP2000 communication from ECU to gateway is interrupted.

Checks:
Check the continuity of KWP2000 communication cable.
1. Between 719 (gateway) and 719 (ECU)

If continuity replace gateway, if error remains replace ECU.

If no continuity replace harness.

If i'm not mistaken there is a box mounted to the front engine compartment plate behind the operator cab area that contains the gateway, ECU and VCM3-0P, the cable and connections to test should be in there.

"Unicarriers - it would have to be for a dual fuel unit also. Usually a bad cam or crankshaft sensor will throw a E-27 or a E-28 code on the dash panel... If it does not light up and the bulb is bad then it will not start also."
