CIRCUIT OPERATION The G-sensor detects acceleration or deceleration, and converts it to a voltage signal
to send to the ABS-ECU (terminal 15). ABS DTC SET CONDITIONS These codes are set at the following cases:
DTC C1381:
G-sensor (out
put seized)
CAUTION: If there is any problem in the CAN bus lines, an
incorrect diagnostic trouble code may be set. Prior to
this diagnosis, diagnose the CAN bus lines.

When there is no variation in the G-sensor output voltage (G-sensor output
seized)
DTC C1382: G-sensor (low signal voltage problem) When the G-sensor output is lower than 0.5 V (Open circuit in G-sensor
circuit) When the ABS-ECU for AWD has installed incorrectly to the FWD vehicle
DTC C1383: G-sensor (high signal voltage problem) When the G-sensor output voltage is higher than 4.5 V (Open circuit in G-
sensor circuit)
TROUBLESHOOTING HINTS (THE MOST LIKELY CAUSES FOR THESE DTCS ARE TO SET ARE:)
Current trouble
Faulty ABS-ECU (for AWD) installation to the FWD vehicle Malfunction of the G-sensor Damaged wiring harness or connector Malfunction of the hydraulic unit (integrated with ABS-ECU)
PAST TROUBLE Carry out diagnosis with particular emphasis on connector(s) or wiring harness
between the ABS-ECU and the G-sensor. For diagnosis procedures, refer to HOW TO USE TROUBLESHOOTING/ INSPECTION SERVICE POINTS
.
DIAGNOSIS Required Special Tools:
MB991958: Scan Tool (MUT-III Sub Assembly)
MB991824: Vehicle Communication Interface (V.C.I.) MB991827: MUT-III USB Cable MB991910: MUT-III Main Harness A

STEP 1. Using scan tool MB991958, diagnose the CAN bus line.
1. Connect scan tool MB991958 to the data link connec
tor. CAUTION: If the ABS-ECU for AWD has installed incorrectly to
FWD vehicle, DTC C1382 is set. Before
troubleshooting, make sure the correct ABS-ECU for
FWD has installed to FWD vehicle.
CAUTION: To prevent damage to scan tool MB991958,
always turn the ignition switch to the
"LOCK" (OFF) position before connecting or
disconnecting scan tool MB991958.

2. Turn the ignition switch to the "ON" position.
3. Diagnose the CAN bus line.
4. Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the CAN bus line found to be normal?
YES: Go to Step 3 .
NO: Repair the CAN bus line (Refer to , TCL/ASC DIAGNOSIS
or
DIAGNOSIS < VEHICLES WITHOUT ADVANCED AIR BAG ).
Then go to Step 2.
STEP 2. Recheck for diagnostic trouble code.
1. Turn the ignition switch to the "ON" position.
2. Erase the DTC.
3. Turn the ignition switch to the "LOCK" (OFF) position.
4. Turn the ignition switch to the "ON" position.
5. Check if the DTC is set. CAUTION: To prevent damage to scan tool MB991958,
always turn the ignition switch to the
"LOCK" (OFF) position before connecting or
disconnecting scan tool MB991958.
