2. INSPECT ANTENNA CORD SUB-ASSEMBLY
(a) Measure the resistance according to the value(s) in the table below.
| *a | Component without harness connected (Antenna Cord Sub-assembly) | - | - |
| *c | Navigation Antenna | - | - |
Standard Resistance:
| Tester Connection | Condition | Specified Condition |
|---|---|---|
| A-1 - B-1 | Always | Below 1 Ω |
| A-2 - B-2 | Always | Below 1 Ω |
| A-3 - B-3 | Always | Below 1 Ω |
| A-4 - B-4 | Always | Below 1 Ω |
If the result is not as specified, replace the antenna cord sub-assembly.

Front Acceleration Sensor RH Malfunction (C1715-C1717,C1796-C1798)
DESCRIPTION The acceleration sensor assembly (up and down G sensor) detects the upward and downward acceleration of the vehicle and outputs it as a voltage to the absorber control ECU. Up and down G sensors are installed in 3 locations: 1) the driver side instrument panel, 2) the passenger side inst
Vehicle Speed Signal Circuit between Navigation ECU and Combination Meter
DESCRIPTION The navigation ECU receives a vehicle speed signal from the combination meter assembly. HINT:
A voltage of 12 V or 5 V is output from each ECU and then input to the combination meter assembly. The signal is changed to a pulse signal at the transistor in the combination meter assembly.
