KOER Wiggle Test
WARNING: This page is about a different car, the 1994 Mazda Navajo. However, it is still accessible from the selected car via links, so may be relevant.
1) Turn ignition off. Connect test equipment. Start engine. Activate self-test using jumper lead or diagnostic tester. Wait 10 seconds, then deactivate and reactivate self-test. DO NOT turn engine off. KOER wiggle test mode is now activated.
2) Tap, move and wiggle suspect sensor and/or harness area. If a fault is detected, scan tester should indicate a tone or light, and VOM will perform needle sweep and/or MIL will come on. A service code may be stored in continuous memory. Retrieve code, and perform appropriate test. See SERVICE CODE REFERENCE.
