C1792

DTC C1792 LEFT FRONT ACCELERATION SENSOR CIRCUIT

CIRCUIT DESCRIPTION

DTC Detecting Condition:

The acceleration sensors detect the up-and-down acceleration of the vehicle. The acceleration sensors (3 in total) are mounted in the suspension control ECU, at the LH side of the cowl and in the rear quarter area, and detect the up-and-down acceleration of the vehicle, respectively. The acceleration sensors convert the resistance into an electrical signal and output to the suspension control ECU.

HINT:
- When DTC C1791/91 is output, follow the same procedure as DTC C1715/15.
- When DTC C1793/93 is output, follow the same procedure as DTC C1717/17.
- Since the acceleration sensor front LH is built into the suspension control ECU, replace suspension control ECU when DTC C1716/16 and C1792/92 are output.

INSPECTION PROCEDURE

HINT:
- If DTC C1761/61 (ECU malfunction) and/or C1774/74 (power source circuit) is displayed, perform the inspection necessary for DTC C1761/61 and/or C1774/74 first. (If DTC C1761/61 and C1774/74 are output at the same time, perform the inspection necessary for DTC C1774/74 first.)
- Start the inspection from the step 1 when using the hand-held tester, and start from step 2 when not using the hand-held tester.
