Test A: No Communication With Abs Control Module
- Check For Open Fuse
Check Battery Junction Box (BJB) maxi-fuse No. F103 (60-amp) and Central Junction Box (CJB) fuse No. F232 (10-amp). See Figure
and Figure
. If fuses are good go to next step. If fuses are blown, replace fuses. Clear codes and repeat self-test. If fuse fails again, check for grounded circuit. Repair as necessary. Reconnect all components, clear codes and repeat self-test.
- Check For Open Circuit
Disconnect 30-pin ABS control module connector. Turn ignition on. Measure voltage between ABS control module connector terminal No. 8 (Orange wire) wiring harness side and ground. See Figure
. If voltage is more than 10 volts, go to next step. If voltage is less than 10 volts, repair Orange wire. Reconnect all components, clear codes and repeat self-test.
- Check For Open Circuit
Turn ignition off. Measure resistance between ABS control module connector terminal No. 12 (Black wire) wiring harness side and ground. If resistance is less than 5 ohms, see appropriate MODULE COMMUNICATIONS NETWORK article in ACCESSORIES & EQUIPMENT. If resistance is more than 5 ohms, repair Black wire. Reconnect all components, clear codes and repeat self-test.
