Lexus ES: Communication Error from ECM to VSC Invalid Serial Data Received (P163181)
DESCRIPTION
The skid control ECU (brake actuator assembly) sends signals such as brake request signals to the ECM. When the ECM detects logic error signals sent from the skid control ECU (brake actuator assembly) for a certain period of time, DTC P163181 is stored.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | DTC Output from |
|---|---|---|---|---|---|
| P163181 | Communication Error from ECM to VSC Invalid Serial Data Received | When the engine switch is on (IG) and the dynamic radar cruise control system is operating, the ECM detects logic error signals sent from the skid control ECU (brake actuator assembly) for approximately 1 second or more. |
| Does not come on | Engine |
CAUTION / NOTICE / HINT
NOTICE:
Before replacing the ECM, refer to Registration.

PROCEDURE
| 1. | CHECK FOR DTCs |
(a) Check for electronically controlled brake system DTCs.
Chassis > Brake/EPB > Trouble Codes| Result | Proceed to |
|---|---|
| Electronically controlled brake system DTCs are not output | A |
| Electronically controlled brake system DTCs are output | B |
| B | .gif) | GO TO ELECTRONICALLY CONTROLLED BRAKE SYSTEM |

| 2. | CHECK FOR DTCs |
(a) Clear the DTCs.
Powertrain > Radar Cruise1 > Clear DTCs(b) Make sure that the DTC detection conditions are met.
HINT:
If the detection conditions are not met, the system cannot detect the malfunction.
(c) Check for DTCs.
Powertrain > Radar Cruise1 > Trouble Codes| Result | Proceed to |
|---|---|
| DTC P163181 is not output | A |
| DTC P163181 is output | B |
| A | | USE SIMULATION METHOD TO CHECK |
| B | | REPLACE ECM |

Generator Shutdown Stuck Off (P1C6C9F)
DTC SUMMARY MALFUNCTION DESCRIPTION The hybrid vehicle control ECU detects malfunctions which prevent the generator (MG1) inverter shutdown circuit from shutting down the hybrid vehicle control system. Detection is performed during the shutdown sequence when the power switch is turned off. If genera
