DTC 15: "G" Sensor Circuit Or Abs Control Module Fault
WARNING: This page is about a different variant/trim than selected.
CAUTION:
A "G" sensor is used on 4WD Suzuki vehicles to detect body deceleration rate.
NOTE:
This code will be displayed on 2WD models if an ABS control module assembly for a 4WD vehicle has been installed.
- Ensure "G" sensor is properly secured to floor. See "G" SENSOR under REMOVAL & INSTALLATION. Turn ignition off and remove "G" sensor with bracket. Check for proper harness connections at "G" sensor. See WIRING DIAGRAMS . If connections are correct, test "G" sensor. See "G" SENSOR under COMPONENT TESTS. Repair or replace as necessary and go to next step.
- Disconnect 16-pin and 26-pin ABS control module harness connectors. Disconnect 3-pin "G" sensor harness connector. Check 16-pin ABS control module harness connector terminals No. 6 (Orange/Black wire) and No. 7 (Orange/White wire) for proper contact and connection. If connections are okay, turn ignition on and measure voltage between 3-pin "G" sensor harness connector terminal No. 3 (Black/White wire) and good body ground point. See Fig 1 . If battery voltage is present, go to next step. If battery voltage is not present, repair open circuit in Black/White wire. See WIRING DIAGRAMS .
- Measure voltage between 3-pin "G" sensor harness connector terminal No. 2 (Orange/White wire) and good body ground point. See Fig 1 . If voltage reading is zero volts, go to next step. If voltage reading is not zero volts, repair short to voltage in Orange/White wire. See WIRING DIAGRAMS .
- Turn ignition off. Check Orange/White wire between 3-pin "G" sensor harness connector terminal No. 2 and 16-pin ABS control module harness connector terminal No. 7 for an open circuit condition. Check Orange/White wire between 3-pin "G" sensor harness connector terminal No. 2 and 16-pin ABS control module harness connector terminal No. 6 (Orange/Black wire) for a short circuit condition. See Figure and Fig 1 . Also check Orange/White wire between 3-pin "G" sensor harness connector terminal No. 2 and good body ground point for short to ground. If Orange/White wire is open, shorted to ground or shorted to Orange/Black wire, repair identified circuit. See WIRING DIAGRAMS . If Orange/White wire is okay, substitute a known-good ABS control module and recheck because Orange/Black wire is open.
