PINPOINT TEST G207085p17

PINPOINT TEST G207085p17 : DTC B2296: FLASH CODE 42: FRONT CRASH SENSOR CIRCUIT MALFUNCTION

G207085t100 : CHECK THE FRONT CRASH SENSOR SIGNAL RETURN CIRCUIT FOR HIGH RESISTANCE
1. Disconnect the battery negative terminal.
2. Wait one minute for the system to become safe.
3. Disconnect the RCM electrical connector, CR87.
4. Disconnect the front crash sensor electrical connector, EC50.
5. Measure the resistance between CR87, pin 20 (W) and EC50, pin 01 (W).

- Is the resistance greater than 5 ohms?

-> YES
REPAIR the high resistance circuit. CLEAR the DTC. TEST the system for normal operation.

-> NO
GO to Pinpoint Test G207085t101.

G207085t101 : CHECK THE FRONT CRASH SENSOR SIGNAL RETURN CIRCUIT FOR SHORT TO GROUND
1. Reconnect the battery negative terminal.
2. Measure the resistance between CR87, pin 20 (W) and GROUND.

- Is the resistance less than 10,000 ohms?

-> YES
REPAIR the short circuit. CLEAR the DTC. TEST the system for normal operation.

-> NO
GO to Pinpoint Test G207085t102.

G207085t102 : CHECK THE FRONT CRASH SENSOR SIGNAL RETURN CIRCUIT FOR SHORT TO HIGH VOLTAGE
1. Measure the voltage between CR87, pin 20 (W) and GROUND.

- Is the voltage greater than 3 volts?

-> YES
REPAIR the short circuit. CLEAR the DTC. TEST the system for normal operation.

-> NO
GO to Pinpoint Test G207085t103.

G207085t103 : CHECK THE FRONT CRASH SENSOR SIGNAL POWER CIRCUIT FOR HIGH RESISTANCE
1. Disconnect the battery negative terminal.

3. Measure the resistance between CR87, pin 19 (N) and EC50, pin 02 (N).

- Is the resistance greater than 5 ohms?

-> YES
REPAIR the high resistance circuit. CLEAR the DTC. TEST the system for normal operation.

-> NO
GO to Pinpoint Test G207085t104.

G207085t104 : CHECK THE FRONT CRASH SENSOR SIGNAL POWER CIRCUIT FOR SHORT TO GROUND
1. Reconnect the battery negative terminal.
2. Measure the resistance between CR87, pin 19 (N) and GROUND.

- Is the resistance less than 10,000 ohms?

-> YES
REPAIR the short circuit. CLEAR the DTC. TEST the system for normal operation.

-> NO
