Mazda 2: Intermittent Concern Troubleshooting
Vibration Method
1. If malfunction occurs or becomes worse while driving on a rough road or
when engine is
vibrating, perform the steps below.
NOTE:
- There are several reasons vehicle or engine vibration could cause an
electrical malfunction. Some of the things to inspect for are:
- Connectors not fully seated
- Wiring harnesses not having full play
- Wiring harnesses laying across brackets or moving parts
- Wiring harnesses routed too close to hot parts
- An improperly routed, improperly clamped, or loose wiring harness can
cause wiring to become pinched between parts.
- The connector joints, points of vibration, and places where wiring
harnesses
pass through the fire wall, body panels, etc. are the major areas to be
inspected.
Inspection Method for Switch Connectors or Wiring Harnesses
1. Connect the M-MDS to the DLC-2.
2. Switch the ignition to ON (engine off).
NOTE:
- If engine starts and runs, perform the following steps during idle.
3. Access the PIDs for the switch you are inspecting.
4. Turn the switch on manually.
5. Slightly shake each connector or wiring harness vertically and horizontally
while
monitoring the PID.
- If the PID value is unstable, inspect for poor connection.

Inspection Method for Sensor Connectors or Wiring Harnesses
1. Connect the M-MDS to the DLC-2.
2. Switch the ignition to ON (engine off).
NOTE:
- If engine starts and runs, perform the following steps during idle.
3. Access the PIDs for the switch you are inspecting.
4. Slightly shake each connector or wiring harness vertically and horizontally
while
monitoring the PID.
- If the PID value is unstable, inspect for poor connection.

Inspection Method for Sensors
1. Connect the M-MDS to the DLC-2.
2. Switch the ignition to ON (engine off).
NOTE:
- If engine starts and runs, perform the following steps at idle.
3. Access the PIDs for the switch you are inspecting.
4. Vibrate the sensor slightly with your finger.
- If the PID value is unstable or malfunction occurs, check for poor
connection
and/or poorly mounted sensor.
Inspection Method for Actuators or Relays
1. Connect the M-MDS to the DLC-2.
2. Switch the ignition to ON (engine off).
NOTE:
- If engine starts and runs, perform the following steps during idle.
3. Prepare the Output State Control for actuators or relays that you are
inspecting.
4. Vibrate the actuator or relay with your finger for 3 s as Output State
Control is activated.
- If variable click sound is heard, inspect for poor connection and/or
poorly
mounted actuator or relay.

NOTE:
- Vibrating relays excessively may result in open relays.
Water Sprinkling Method
CAUTION:
If malfunction occurs only during high humidity or rainy/snowy weather,
perform the following steps.
1. Connect M-MDS to the DLC-2 if inspecting sensors or switches.
2. Switch the ignition to ON (engine off).
NOTE:
- If the engine starts and runs, perform the following steps during idle.
3. Access the PIDs for sensor or switch if inspecting sensors or switches.
4. If you are inspecting the switch, turn it on manually.
5. Spray water onto the vehicle or run it through a car wash.
- If the PID value is unstable or malfunction occurs, repair or replace
part.

Main Relay Operation Inspection
1. Verify that the main relay clicks when the ignition switch is turned to
the ON position, then off.
If there is no operation sound, inspect the following:

If the accelerator pedal is depressed continuously for a specified time,
the engine speed
may decrease to the idle speed. This is due to the fuel cut control
