Honda HR-V (2015-2021) Service Manual / Accessories & Equipment / Gauges - Testing & Troubleshooting / Testing / ECON Switch Test
Test
1. Driver's Dashboard Lower Cover - Remove
2. ECON Switch - Test

- Check the ECON switch (A) according to the table.
NOTE:
- When an LED is located between terminals, check if the LED illuminates by connecting power and ground to the LED.
- Note this important operating characteristic; diode bias causes a diode to fully conduct electricity in one direction (forward), while not at all in the opposite direction (reverse).

- If the result is not as specified, replace the ECON switch.
3. All Removed Parts - Install
- Install the parts in the reverse order of removal.
GAUGE CONTROL MODULE INPUT TEST
NOTE:
- Before testing, do the gauge control module self-diagnostic function, and make sure the B-CAN communication lines are OK.
- If you are troubleshooting multiple DTCs, be sure to follow the instructions in B-CAN System Diagnosis Test Mode A - Refer to: Body Electrical Troubleshooting - B-CAN System Diagnosis Test Mode A - Initial Communication and DTC Checks,.
- Before testing, make sure the No. B21 (10 A) fuse in the under-hood fuse/relay box is OK.
- Before testing, make sure the No. C34 (7.5 A) fuse in the under-dash fuse/relay box is OK.
- Turn the vehicle to the OFF (LOCK) mode
- Disconnect the gauge control module connector A (32P).

- Inspect the connector and socket terminals to be sure they are all
making good contact:
- If the terminals are bent, loose, or corroded, repair them as necessary, and recheck the system.
- If the terminals are OK, go to step 4.
- With the connector still disconnected, do the following input tests:
- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, go to step 5.

- Reconnect the connector, and do the following input tests:
- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, replace the gauge control module.

Interpreting A Current Controlled Pattern
NOTE: Current controlled drivers are also known as "Peak and Hold"
drivers. They
typically require injector circuits with a total leg resistance with less than
12
ohm.
NOTE: This example is based on a constant power/switched ground circuit.
