HYBRID / BATTERY CONTROL: HYBRID CONTROL SYSTEM: P3137-348,P3138-349: Collision Sensor Low Input
P3138-349 - Collision Sensor High Input

DESCRIPTION

- The power management control ECU (HV CPU) monitors the connection status of the No.1 circuit breaker sensor signal (collision signal) line. If the ECU detects a malfunction, it will alert the driver.

(c) Turn the power switch off.

NG -- INSPECT NO.1 CIRCUIT BREAKER SENSOR
OK -- Continue to next step.

2. CLEAR DTC (HV)

(a) Connect the Techstream to the DLC3.

(b) Turn the power switch on (IG).

(c) Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.

(d) Read and record the DTCs and freeze frame data.

(e) Clear DTCs and freeze frame data.

(f) Turn the power switch off.

NEXT -- Continue to next step.

3. CHECK DTC OUTPUT (HV)

(a) Connect the Techstream to the DLC3.

(b) Turn the power switch on (IG).

(c) Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.

(d) Check if DTCs are output.

Result:





(e) Turn the power switch off.

B -- CHECK FOR INTERMITTENT PROBLEMS Check For Intermittent Problems

A -- REPLACE POWER MANAGEMENT CONTROL ECU Components

4. INSPECT NO.1 CIRCUIT BREAKER SENSOR

(a) Disconnect the g9 connector from the No. 1 circuit breaker sensor.

(b) Measure the resistance according to the value(s) in the table below.





Standard Resistance:
