DTC C1119 (83)

BME040243000214

## L3, AJ

  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 PCM CONNECTOR AND GROUND) • Turn ignition key to OFF. • Disconnect PCM connector. • Turn ignition key ON (engine OFF). • Measure voltage between 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 PCM connector (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 PCM CONNECTOR AND GROUND FOR SHORT TO GROUND • Inspect continuity between PCM connector (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.

## MZR-CD (RF Turbo)

DTC | C1119 (83) | Engine control system, torque reduction inhibit information
DETECTION CONDITION | • Torque reduction inhibit information through CAN is out of specification or invalid value. • Received control prohibition signal from PCM through CAN.
POSSIBLE CAUSE | • Malfunction of PCM

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | CHECK FOR PCM FOR DTCs • Turn ignition key to OFF. • Connect WDS or equivalent to DLC-2 • Turn ignition key to ON (engine off). • Is DTC for engine control system obtained? | Yes | Follow inspection procedures for engine control system.
No | Go to next step.
2 | VERIFY TROUBLESHOOTING COMPLETED • Make sure to reconnect all disconnected connectors. • Clear DTC from memory. (See Clearing DTCs Procedure • Start engine.)
• Is same DTC present?
Yes
Replace ABS/TCS HU/CM, then go to next step.
No | Go to next step.
3 | VERIFY AFTER REPAIR PROCEDURE • Is there any other DTC present? | Yes | Go to applicable DTC inspection.
No | Troubleshooting completed.
