DTC 94: Side Impact Sensor (RH) Power Supply Circuit System: Diagnosis
Required Special Tools:
- MB991502: Scan Tool (MUT-II)
- MB991223 (MB991222): Harness Set (Probe)
- STEP 1. Check the side impact sensor (RH) power supply circuit at the side impact sensor (RH) connector D-25.
- Disconnect the side impact sensor (RH) connector D-25, and measure at the wiring harness side.
- Connect the negative battery terminal.
- Turn the ignition switch to the "ON" position.
CAUTION: Do not insert a test probe into the terminal from its front side directly as the connector contact pressure may be weakened.
- Measure the voltage between the D-25 harness side connector terminal 2 and body ground.
Voltage should be 9 volts or more.
Q: Is the measured voltage within the specified range?
YES : Replace the side impact sensor (RH) (Refer to SIDE IMPACT SENSOR ). Then 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 94 sets, replace the SRS-ECU (Refer to SRS CONTROL UNIT (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 94 set?
YES : Return to Step 1.
NO: The procedure is complete (If no malfunctions are found in all steps, an intermittent malfunction is suspected. Refer to TO COPE WITH INTERMITTENT MALFUNCTION ).
