DTC 94

Side Impact Sensor (RH) Power Supply Circuit:

Connectors:

CIRCUIT OPERATION
- The SRS-ECU judges how severe a collision is by detecting signals from the side impact sensor and the analog G-sensor. If the impact is over a predetermined level, the SRS-ECU outputs an ignition signal. At this time, if the safing G-sensor is on, the SRS air bag will inflate.

DTC SET CONDITIONS
- This DTC is output if the power supply voltage of the side impact sensor (RH) drops below the rated value for a continuous period of 5 seconds or more. However, DTC number 94 will be automatically cleared and the SRS warning light will switch off if the condition returns to normal.

TROUBLESHOOTING HINTS
- Damaged wiring harnesses or connectors
- Malfunction of the side air bag module (RH) (squib)
- Malfunction of the SRS-ECU

DIAGNOSIS

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







STEP 1. Check the side impact sensor (RH) line at the SRS-ECU connector C-74 by backprobing.
1. Do disconnect the side impact sensor (RH) connector D-02.
2. Connect the negative battery terminal.
3. Turn the ignition switch to "ON" position.
4. Measure the voltage between terminal 4 and the ground by backprobing.
- Voltage should be 9 volts or more.

5. Check the continuity between terminal 1 and the ground by backprobing.
- Should be less than 2 Ohms.

Q: Does the voltage meet the specifications or is the resistance less than 2 Ohms?

YES: Replace the side impact sensor (LH). Then go to Step 3.

NO: Go to Step 2.







STEP 2. Check the harness wires between SRS-ECU connector C-74 and side Impact sensor (RH) connector D-02.

Q: Are the harness wires between SRS-ECU connector C-74 and side impact sensor (RH) connector D-02 in good condition?

YES: Go to Step 3.

NO: Repair them. Then go to Step 3.

STEP 3. Check for DTC.

Q: Is DTC 94 output?

YES: Replace the SRS-ECU.

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