INSPECTION
PROCEDURE
1. INSPECT STEERING HEATER SWITCH
(a) Check the resistance.
(1) Measure the resistance according to the value(s) in the table below. Standard Resistance: Tester Connection | Condition | Specified Condition | 5 (IG) - 2 (B) | Steering heater switch is pushed | Below 1 Ω | 5 (IG) - 2 (B) | Steering heater switch is not pushed | 10 kΩ or higher | If the result is not as specified, replace the steering heater switch. |
| *a | Component without harness connected (Steering Heater Switch) | | |
(b) Check the indicator.
(1) Apply auxiliary battery voltage to the steering heater switch and check that the indicator illuminates. OK: Tester Connection | Condition | Specified Condition | 2 (B) - 4 (E) | 2 (B) → Auxiliary battery positive (+) 4 (E) → Auxiliary battery negative (-) | Indicator illuminates | If the result is not as specified, replace the steering heater switch. |
| *a | Component without harness connected (Steering Heater Switch) | | |
(c) Check the illumination.
(1) Apply auxiliary battery voltage to the steering heater switch and check that the illumination. OK: Tester Connection | Condition | Specified Condition | 6 (ILL+) - 1 (ILL-) | 6 (ILL+) → Auxiliary battery positive (+) 1 (ILL-) → Auxiliary battery negative (-) | Illumination illuminates | If the result is not as specified, replace the steering heater switch. |

Other information:
DESCRIPTION When TRC or VSC is operating, the skid control ECU (brake actuator assembly) blinks the slip indicator light to inform the driver that slippage occurred. When in VSC off mode, or TRC and VSC are disabled, the multi-information display in the combination meter assembly displays TRC OFF message and the VSC OFF indicator light illuminates to inform the driver...
MONITOR DESCRIPTION The ECM monitors the output voltage to the throttle actuator. This self-check ensures that the ECM is functioning properly. The output voltage is usually 0 V when the ignition switch is turned off. If the output voltage is 7 V or higher when the ignition switch is turned off, the ECM will illuminate the MIL and store this DTC when the ignition switch is turned to ON...
