Test A: 4-Wheel Anti-Lock Control System Does Not Respond To NGS
WARNING: This page is about a different car, the 1997 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
- Turn ignition off. Disconnect 4-wheel ABS control module 24-pin connector C146 (located at left front of engine compartment, on front of upper radiator support). Inspect anti-lock brake module connector C146 for damage. If anti-lock brake module connector is okay, go to next step. If anti-lock brake module connector is damaged, repair as necessary. Retest system for normal operation.
- Using DVOM, check resistance of Light Blue/White wire between 4-wheel ABS control module 24-pin connector C146 pin No. 5 and DLC pin No. 7. See Figure and Fig 1. If resistance is 5 ohms or more, go to next step. If resistance is less than 5 ohms, replace ABS module. Retest system for normal operation.
- Ensure ignition is off. Disconnect 40-pin harness connector C160 (on driver's side of engine compartment near safety wall). Inspect harness connector C160 for damage. If harness connector C160 is okay, go to next step. If harness connector C160 is damaged, repair as necessary. Retest system for normal operation.
- Using DVOM, check resistance of Light Blue/White wire between 4-wheel ABS control module 24-pin connector C146 pin No. 5 and 40-pin harness connector C160 pin No. 29. See Fig 1 and Fig 2. If resistance is less than 5 ohms, repair Light Blue/White wire between 40-pin harness connector C160 and DLC. If resistance is 5 ohms or more, repair Light Blue/White wire between 4-wheel ABS control module 24-pin connector C146 and 40-pin harness connector C160. Retest system for normal operation.
