Test B: Anti-Lock Brake System/Traction Control (Abs/TC) Module Does Not Respond To NGS Tester
- Turn ignition off. Disconnect 76-pin Gray connector C101 located in left rear of engine compartment, on safety wall. Inspect connector for loose, damaged or corroded terminals. Repair connector as necessary and retest system for normal operation. If connector is okay, measure resistance of Tan/Orange wire between terminal No. 56 at connector C101 and terminal No. 2 at DLC. See Figure and Figure. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open Tan/Orange wire between connector C101 and DLC. Retest system for normal operation.
- Measure resistance of Pink/Light Blue wire between terminal No. 55 at connector C101 and terminal No. 10 at DLC. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open Pink/Light Blue wire between connector C101 and DLC. Retest system for normal operation.
- Disconnect ABS/TC module connector located in left rear of engine compartment. Inspect connector for loose, damaged or corroded terminals. Repair connector as necessary and retest system for normal operation. If connector is okay, measure resistance of Tan/Orange wire between terminal No. 56 at connector C101 and terminal No. 17 at ABS/TC module connector. See Figure and Fig 1. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open Tan/Orange wire between ABS/TC module connector and connector C101. Retest system for proper operation.
- Measure resistance of Pink/Light Blue wire between terminal No. 55 at connector C101 and terminal No. 16 at ABS/TC module connector. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open Tan/Orange wire between ABS/TC module connector and connector C101. Retest system for proper operation.
- Inspect ABS/TC module connector for loose, damaged or corroded terminals. Repair connector as necessary and retest system for normal operation. If connector is okay, replace ABS/TC module. Repeat DATA LINK DIAGNOSTIC TEST under COMMUNICATIONS NETWORK DIAGNOSTICS to confirm repair.
