Using Hybrid Electronic Cluster
WARNING: This page is about a different car, the 2002 Lincoln Blackwood. However, it is still accessible from the selected car via links, so may be relevant.
To enter Hybrid Electronic Cluster (HEC) self-diagnostics, press and hold instrument cluster SELECT/RESET button while turning ignition switch from OFF to RUN position. Within 5-8 seconds, odometer will display "tESt". SELECT/RESET button must be released within 3 seconds of odometer displaying "tESt" then, repeatedly press SELECT/RESET button through odometer displays until "dtc" is displayed. When odometer displays "dtc", press SELECT/RESET button again and any continuous diagnostic trouble codes will be displayed before odometer advances to next display. Other HEC diagnostic modes can be entered when self-diagnostic function is entered. See HYBRID ELECTRONIC CLUSTER SELF-DIAGNOSTIC MODES table.
HYBRID ELECTRONIC CLUSTER SELF-DIAGNOSTIC MODES
| Odometer Display(1) | Description | ||
|---|---|---|---|
| GAGE | Activates sweep of all gauges, then displays present gauge values. Performs ROM and EE checksum tests. | ||
| All Segments Illuminated | Illuminates all odometer segments. | ||
| bulb | Illuminates all micro-controlled lights and LEDs. Replace bulb or LED as necessary. | ||
| r | Returns to normal operation all micro-controlled lights and LEDs and displays hexadecimal values for ROM. | ||
| EE | Hexadecimal value for EE level. | ||
| dt | Displays hexadecimal coding of final manufacturing test date. | ||
| dtc | Displays continuous DTCs. Pressing SELECT/RESET button will display any DTCs stored before proceeding to next step. | ||
| enG | English value speed input. Display will indicate zero, if input is not received or invalid for more than one second, or when vehicle speed is zero. | ||
| m | Metric speed value input. Display will indicate zero, if input is not received or invalid for more than one second or when vehicle speed is zero. | ||
| tAc | Tachometer value input. Display will indicate zero, if input is not received or invalid for more than one second or when engine speed is zero. | ||
| FUEL | Fuel level input. Displays 255 for open circuit, about 232 for full stop, 215 for full tank, 178 for 3/4 full, 138 for 1/2 full, 93 for 1/4 full, 41 for empty mark, 0-20 for circuit is shorted. Below 55 low fuel warning light should light. | ||
| OIL | Oil pressure input. Normal input reading will be 000-176. Below 6 psi or inoperative switch will be greater than 176. | ||
| dEGC | Last coolant temp input. About 120°F (49°C), gauge should be at cold mark; 140°F (60°C) gauge should be at beginning of normal band. 248°F (120°C) gauge should be at end of normal band. About 246°F (119°C), temperature warning light should light. | ||
| br | Brake fluid level input. | ||
| bAtt | Battery voltage input. 93-102 = 6.9-9.1 volts; 115-124 = 8.5-10.7 volts; 215-225 = 15.8-18.0 volts & 230-241 = 16.9-19.1 volts. | ||
| rhEo | Displays hexadecimal value for instrument cluster pulse width modulated input to HEC. | ||
| rhi, rhS & rho | Pulse width modulated input duty cycle. SCP hexadecimal dimming step. Output driver counts in hexadecimal format. | ||
| Cr | RUN/START sense input. Shows -h with ignition switch in START, -L with ignition switch in RUN position. | ||
| PA-PE7 | Not used. | ||
| GAGE | Repeats test display cycle. | ||
