DTC C1119 (83)

BME040200000W19

  Caution

  • When attaching the tester lead to the ABS/TCS HU/CM harness connector, the SST (49 G066 001) must be used. (See ABS/TCS HU/CM INSPECTION.)

DTC | C1119 (83) | Torque reduction inhibit signal line
DETECTION CONDITION | • After engine is started, malfunction of torque reduction inhibit signal line is detected.
POSSIBLE CAUSE | • Open or short circuit of torque reduction inhibit line

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY WHETHER MALFUNCTION IS IN WIRING HARNESS (BETWEEN 2C TERMINAL OF PCM AND GROUND) • Turn ignition key to OFF. • Disconnect PCM connector. • Turn ignition key ON (engine OFF). • Measure voltage between terminal 2C of PCM connector (harness side) and GND.

Voltage

Approx. 5 V

• Is voltage as specified?
Yes
Go to Step 4.
No | Go to next step.
2 | INSPECT WIRING HARNESS BETWEEN ABS/TCS HU/CM AND PCM FOR CONTINUITY • Turn ignition key to OFF. • Disconnect ABS/TCS HU/CM connector. • Connect SST (adapter harness) to ABS/TCS HU/CM (harness side). • Inspect for continuity between terminal 2C of PCM harness side and terminal L of SST (adapter harness).
• Is there continuity?
Yes
Go to next Step.
No | Repair or replace harness, then go to Step 5.
3 | INSPECT WIRING HARNESS BETWEEN 2C TERMINAL OF PCM AND GROUND FOR SHORT TO GROUND • Inspect continuity between terminal 2C of PCM harness side and ground. • Is there continuity? | Yes | Repair or replace harness, then go to Step 5.
No | Go to Step 5.
4 | INSPECT VOLTAGE PATTERN AT TERMINAL L OF ABS/TCS HU/CM • Connect PCM connector and SST (adapter harness) to ABS/TCS HU/CM (ABS/TCS HU/CM side). • Turn ignition key to ON. • Inspect voltage pattern at ABS/TCS HU/CM terminal L using oscilloscope. | Yes | Go to Step 5.
No | Replace PCM, then go to Step 5.
• Is voltage pattern as specified?
5 | VERIFY TROUBLESHOOTING COMPLETED • Clear DTC from memory. (See Clearing DTCs Procedure) • Is the same DTC present? | Yes | Replace ABS/TCS HU/CM, then go to next step.
No | Go to next step.
6 | VERIFY AFTER REPAIR PROCEDURE • Is there any DTC present? | Yes | Go to applicable DTC inspection.
No | Troubleshooting completed.
