DTC 96

Side Impact Sensor (RH) Disabled Communication System

Side Impact Sensor (RH) Circuit:

CIRCUIT OPERATION
The side impact sensor includes an analog G sensor and CPU, etc. The CPU monitors the analog G sensor output signal. If the CPU judges that the side-airbags should be deployed, it sends an ignition signal to the SRS-ECU to deploy the side-airbags. Besides that, the CPU diagnoses the internal components of the side impact sensor. If a malfunction occurs, it requests the SRS-ECU to set a diagnostic trouble code.

DTC SET CONDITIONS
These DTC are set if communication between the side impact sensor (RH) and the SRS-ECU is not possible or faulty.

TROUBLESHOOTING HINTS
- Damaged wiring harnesses or connectors
- Malfunction of the side impact sensor (RH)
- Malfunction of the SRS-ECU

DIAGNOSIS

Required Special Tool:
- MB991502: Scan Tool (MUT-II)

STEP 1. Check the side Impact sensor (RH).
1. Replace the side impact sensor (RH) with the side impact sensor (LH).
2. Connect the negative battery terminal.
3. Erase DTC memory, and then recheck the DTC.

Q: Is DTC 79 or 93 set?

YES: Replace the side impact sensor (RH) with a new one. Go to Step 3.
NO: Go to Step 2.







STEP 2. Check the harness wires for open circuit or short
circuit between the SRS-ECU connector C-145 (terminal No.40 and 42) and the side impact sensor (RH) connector D-25 (terminal No.1 and 2).

Q: Are the harness wires between the SRS-ECU connector C.145 (terminal No.40 and 42) and the side impact sensor (RH) connector D-25 (terminal No.1 and 2) in good condition?

YES: Erase the DTC memory, and recheck if any DTC sets. If DTC 89 or 96 sets, replace the SRS-ECU. Then go to Step 3.
NO: Repair the harness wires between the SRS-ECU connector C-145 and the side impact sensor (RH) connector D-25. Then go to Step 3.

STEP 3. Check for DTC.

Q: Is DTC 89 set?

YES: Refer to Step 1.
NO: The procedure is complete. (If no malfunctions are not found in all steps, an intermittent malfunction is suspected. Refer to INTRODUCTION, How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction.)
